Provent / catchcan fitment kits. [Archive]

Hey all,

Well a LONG overdue promise to provide Provent kits to the VW community is finally happening. I'll be chasing up all those PM's of interest in the coming weeks!

http://www.vwwatercooled.com.au/forums/images/imported/2010/11/proventrange-2.jpg

I can supply Provent 200's ( far right ) at $175, which matches the best price anywhere. Certainly a lot cheaper than I paid for mine! The kit is in final prototype, and will suit the MKV and MK6 TDI's first, and then expand from there. It will simply clip onto the inlet and outlet ports in the engine bay, and I'm down to making it work with the engine cover and getting a nice bracket made up. It will be universal, and you will be able to order as much or as little of it as you want. Purosil silicon hose is included, and is available is any colour as long as it's blue, but there are options there. Pricing is still being finalised and will be offered in a drain back into the sump system I'm currently testing, or into a lower can that needs be periodically drained. Heck even a clear hose with a tap on the end will do, it's up to the customer, and all options will be available. I'm also planning to investigate the other Provents in the range.

I am concentrating on the diesel models for now, as they have the greatest need, but it'll be just as easy to fit one to a petrol model. Petrol cars can get away with a cheaper can, and the best one for the money out there at the moment in my humble opinion is the 42 draft designs one, the "Stealth" being the same internally as the much fancier, and more costly, "Ultimate". With a mechanical layered sieve, this will collect a lot of the blowby, but I've yet to quantify that. They have an exceptional 2.0 FSI solution kit, and are currently in testing of another even more comprehensive kit again. I'd suggest this can is more suited to the petrol cars with less blowby due to lesser compression, and it has no consumables, just needs to be drained from time to time.

http://www.vwwatercooled.com.au/forums/images/imported/2010/11/cc_all-2.jpg

Finally I can now formally announce that I am the Australian agent for 42 Draft Designs, and have a lot of the items outside exhausts already in stock. The catch cans are the big drawcard there, and I am working on a bracket for our Aussie cars with 42DD.

I've also got my eye on the only other half decent inexpensive catch can out there, but that's down the line somewhat, much to do already.

I've called my new baby "Carformance". Website is getting close. Stay tuned!

Good mate is a full time web designer and he's on the case, but I'm using Magento free source as my e-commerce shop. I'm getting my head around it as we speak, it's pretty full on, but oh so clever. I aim to tinker on the website as well, it's my nature!

I have several sets of all the shift bushings in stock, they will undoubtably be the biggest seller in 42DD. Loving mine!

Very interesting - and good on ya for doing this for the community.

I guess I'll need to take a good look at an MkV and MkVI engine bay to see how similar they are to the Tiguan bay. I'm interested in getting one of these, but only if it's idiot-proof to install as I am less than handy with this sort of thing.

I'll be watching this thread with great interest!

Greg Roles

Basically to fit to any TDI, all you need is to find the space, and I need to supply a car specific bracket. The aim is to make it a simple plug and play, and if you can remove the engine cover, and bolt on a bracket, you should be set. I have some Provents coming in today, and they are my test dummies to make up the brackets. I'm starting with the Golf basically because there's one parked in my garage!

I'd HIGHLY recommend every TDI out there fit a Provent, and they are available from Western Filters in Sydney, e-bay ( Western Filters again ) and me all at $175. Promise I'll do a Tig and Toureg kit next, the Passat, Skoda etc should virtually be a golf. Pogo's, well I'll have to investigate the Provent 150 and 100, the 200's smaller cousins, as it's a tight engine bay! Even the baby Provent 100 is rated up to 100kw and 100L/min of blowby, so that's impressive for the size.

Once I get into the swing of it, and get nice brackets happening, should be pretty quick to punch out varients on these things.

I've also got some Audi boys on my case with the 42DD cans, so it's going to be a busy Christmas!

Greg Roles

25-11-2010, 12:09 PM

Was contacted by the Brisbane Mann and Hummel agent - Active Air Spares - today and they too are now doing plain Provents at the $175 mark, so times are good for the Provent clan!

Friggen $50 less than I paid back in 2008!

Congratulations Greg,

Would you like the measurements of my bracket for T5? I can measure the hoses and put together simple instructions, if you like.

Also I looked in the Touareg engine bay today and it will be struggle to fit the Provent there, but it can be done with relocating one component.

You have PM mate but it's at the test stage - I have a one way PCV valve for the drain and am awaiting a part from 42DD to see if I can have the drain pumbed back into the crankcase to make it a truly enclosed system, only need to swap Provent inserts every 30k or so.

The OEM VW connectors are a ludicrous $45 for two at virtually trade, so am trying to get quantity direct from the manufacturer, and this is proving to be difficult as it appears these connectors are made under licence specifically for VW/Audi.

I am getting close though!!

Greg Roles

14-01-2011, 07:51 AM

Appreciate the offer monkey, but it's all down to sourcing a few final bits at sensible prices.

I have found the exact VW / Audi connectors from their source, and am just trying to get them to get back to me. I have bought two from VW, but at $22.50 each, well it's a trifle expensive for what they are! There were none in Australia either....

I'm at the final fitment stage on my own car of the PCV return line for the collected oil, and have a few versions of brackets to finalise. I'm adding all these options to a very comprehensive site I'm in the final stages of building, and from the Provent side I've wanted to be competitive, and offer each bit or a whole kit, so people can get what they need. I know this has taken a while, but with everyone from Tigs to Audi's asking me for a "kit" it's been a mission. I'm waiting till it can be done right, at the right price, with all the right options, but I'd realistically say I'm down to the final weeks.

I also have Mann looking into getting me the Provent 100 and 150 for the smaller cars, or those with no room in their engine bays. The number equates to KW, and as long as they don't pose a restriction, two 100's in parallel would equal one 200, so I'm investigating minimal space options too!

I have a very comprehensive e-commerce website almost finished, and as I've been doing most of it myself, it's been a learning curve to say the least. I will have options at all price points, so it can be as cheap or as bling as you want, and there will be detailed fitment videos now that I've finally bought a new PC that can handle HD video editing. I don't want to launch a half done website, so I've been holding off till it's finalised, but believe me I'm itching to go.

Hang in there lads!

OK, finally got to have a chat to the QLD rep for Norma, the people that make the quickconnect V2 connector we need. At this stage there isn't even a part number for the connectors at Norma, and I'm only the second person in Qld after them, but they are apparently working on a connector more suitable to rubber hose; the current ones ( that I'm using very successfully by the by ) are designed for press fitted plastic hose, and I've been told the problem is safety and warranty. Norma are reluctant to let the current connectors be used with rubber hose, but they told me they are probably only several weeks away from releasing a connector with the typical multiple barb fitting to suit rubber hoses. So realistically it's going to be quarter 2 at best for the perfect connector aftermarket.

The next problem is an Audi I'm trying to help John the ownet fit a flash Ultimate 42DD catch can to has 45degree connectors rather than the typical 90degree VW ones. I've just bought the first pair of connectors in the country from VW who had to import them at a rather scary $45 odd. So it would seem that if you're unwilling to either sacrifice your stock PCV hose and use the connectors like I did, or await Norma bringing something to market, you're going to have to pay the dollars the dealer wants to charge.

In the meantime I've got a great modular bracket happrning with 42DDs help, and am awaiting another trick bit from them to hopefully perfect the drain back to dump system I'm trialling.

With all this leadtime they'll want to be pretty darn good eh?

I don't think anyone will have any issues using their stock connectors like you did, its not like someone will ever really want to return the car back to stock standard after installing the Provent kit anyway.

Lockie please see post #22 above mate! The polo has the problem of space, and I'm awaiting a Provent 150 and 100 from Mann and Hummel for the space challenged cars for testing.

Poytie I hear you, and my site will be up in about 2 weeks with ALL options, and you can buy as much or as little of a "kit" as you want. It will only suit those for now who like you are willing to use their stock connectors, and will be added to as new stuff comes through. My modular bracket will take a bit of work to fit all cars, but it's currently looking good for the Golf, Tig and Caddy.

Maybe a silly question but would a dealer fit to a new car on delivery ? I'm assuming some holes need to be drilled for the bracket and I'd rather avoid doing that to my CC when it arrives. Especially with my supreme handy man skills.

By the way ... Will the CC be the same as the Passat bracket you are going to fabricate or will that be a different one ?

My dealer is Crick Motors on the Sunshine Coast (Adam). They have been great even though all done on the phone.

Greg Roles

06-02-2011, 08:28 AM

Not a silly question, but I doubt a dealer would fit a catch can at least until I have them somewhat approved by VW. Cricks do indeed rock though, my dealer. I must admit I haven't even looked at the Passat as yet, it's a mission to try and come up with a bracket for every car / engine combination, but my whole aim is no holes, just use an existing bolt or two. My advice is buy your car, drive it, stay tuned, and I promise it will be a super easy, well explained, video supported fitment process once I'm done.

Evaded drop me a PM, I need the MY year, as it changes the shift cable ends, or I may have to send you both. I'm looking at the smaller Provent 150 for the Polo's, still trying to get one into the country vian Mann and Hummel for testing. You guys have limited engine bay room!!

My website is live, no Provent stuff as yet, but all my prices on the 42DD stuff are finalised. See my sig or sponsor section for links.

Now back to brackets!!!

Recirculation system for Provent drain.

http://www.vwwatercooled.com.au/forums/images/imported/2011/02/relokit011-2.jpg

I've had this running for a few weeks now with zero problems. The Provent drains through a Mann and Hummel one way PCV valve ( which is awesome compared to a few I've tried ) into the 42DD remote block, where it drains back into the sump on shutdown.

http://www.vwwatercooled.com.au/forums/images/imported/2011/02/IMAG0046-1.jpg

Oil pressure seals the valve when running, and the Provent runs as per normal. As it only collects a few mL per day there's little chance of overflow in a normal 1/2" drain hose. When the oil pressure stops, it drains down into the block, and enters the oil filter.

http://www.vwwatercooled.com.au/forums/images/imported/2011/02/IMAG0043-2.jpg

There are one way valves to keep oil in the filter for next startup, so I'm monitoring the line to see if it does indeed drain. So far it looks fine, but I'll let it go another few weeks before drawing any conclusion. I've added my oil pressure sender to the block ( the bell on the left ), but it comes with blank plugs, so you would only need two ports for a normal drain, with the oil entering on the bottom, and the stock pressure sender in the top in the following picture ( the remote hose taps in where this stock sender bolts in ).

http://www.vwwatercooled.com.au/forums/images/imported/2011/02/IMAG0034-1.jpg

The VW oil filter is never full on checking, so there is always space for oil to drain into, but obviously this will only work if the Provent is above the oil inlet back into the filter housing. It would be simple to plumb this into the sump drain plug using the 42DD oil drain bolt with sensor adaptor, but that would be a bit more tricky as this gets in the way at service time. Still I have my temp probe down there, and it's a minor hassle at best every few months. Obviously you can only replace the washer on oil change, but I've yet to have a problem doing that for about 50k now.

http://www.vwwatercooled.com.au/forums/images/imported/2011/02/drainplugadaptor-2.jpg

Will keep you all informed, but very happy so far, and zero mess!!!

Any news on a kit for the 6R Polo ?

Greg Roles

17-06-2011, 02:37 PM

Mate it comes down to working out a mounting place, and in the Polo the problem is room. I have a Provent 100 on order from Germany, will be the first one into Oz, but you would need to run two in parallel, and that gets expensive. If you have a petrol, look at the FAR cheaper and easier to fit 42DD, Forge or similar inner baffle cans, the Provent 200 whilst the top end of things is physically big, and a bit of overkill on apetrol, especially if space is limited. Also, the Provent needs an inner filter every 30k or so, the other cans need nothing but draining from time to time.

Kits for all cars is an immense task, having enough trouble finalising the GTI/R which are the easiest to fit given the space their inlet system frees up. I am making progress on the other cars, but it's slow, and harder than I imagined.

gldgti

17-06-2011, 02:40 PM

Greg...

I'm not convinced that you would need 2 100's to do the job. From what I read, and seeing how the 200 copes and the recommendations from the documentation, I think a 100 would be enough for our engines.... but, feel free to point out that I'm wrong if you know better!

Greg Roles

22-07-2011, 12:47 PM

If my latest hose trial remains positive as it has thus far, then yes.

I am reluctant to put out a kit with a hose that will give out too soon, and oil needs a pretty specific hose, especially in silicon. I realise this has been "going" to happen for quite some time, but I'll have to take a picture of all the hose samples I have at home, and to date, just on hose, I've spent somewhere towards a grand getting lengths to try! I test them for a few months on my own car, and have a few sets "out there" on customers cars to see how they survive.

The latest hose is silicon, black, and holding up perfectly, and I've had some in oil, petrol and diesel for near 12 weeks now, and they are all perfect, no detoriation. Odd that it all comes down to hose, but yep, that's where it's at.

I am feeling very close though!

that doesnt exist - they can, and do, make anything and everything these days - and the rest of the world pays them to do it for us - from whole cars to silicone chips and cheap plastic toys. theres not a thing in everyday life you can name that china can't manufacture that we can - especially because most of our good manufacturing companies have died out, a long time ago, and their knowledge is gone aswell. Infact, they could probably even manufacture it better, but the world market has driven their economy to produce large quantities of mediocre goods, and so they do - and we all buy it, because like transporter says - everyone wants a bargain (but noone can spot quality or good value).

and where are we left? with a small sector of companies manufacturing goods for our own markets, a couple of clever design companies and the remaining 90% of industry selling natural resources to china so they can value add it and sell it back to us, and everyone else.

You can get Provents delivered from Western Filter and the like on e-bay for $170, which is a bloody good price, I have to buy quantity to make it worthwhile at that sort of deal, so again, I'm putting this in the mid to longer term basket. Grab them off e-bay for now.

The Provent 150 cost the same as the 200, flowed far less, was considerably poorer in it's design in my opinion, so if you have a diesel, you need to make the 200 fit - somewhere. You are right that zip ties are fine, the can just needs to be held to stop it flapping around, doesn't need structural support really.

As always, your advice is invaluable - I just wish the Provent 150 was in the same ball park as the 200 since there is so little room under my bonnet :(

BTW Do you see any problem if I downloaded and used the PWGPro 3.93 software from the Alientech site with my V-Switch? The Viezu branded version of PWGPro that I have is only 3.80.
Also, I will be dynoing my 3 Viezu maps vs the stock one for my 1.9 PD soon - would you like me to send you copies for reference?

Also the filter does not have to be replaced every 10k km but probably 50k km. so putting it where I have, only means uncliping a few sensors above it. I think it is harder to get my oil filter out the way it is stuffed in there!

I am having trouble fitting my provent :(

The only place I can find to install it on the T4 would require 3 meters of hose! Is the provent the still working right or is this simply a too long way to travel for the oil vapors?

Transporter

04-06-2012, 06:27 PM

In that case, I would keep the hoses as straight as possible with the minimum bends, also would use 25mm hose. Can you relocate anything in the engine bay?

14-09-2012, 05:19 PM

Hi Greg. I had a look at the installation video on carformance. Where does the one way pcv valve fit?? and you had stated earlier that you were looking at different hoses (it all comes down to the hose.). Which one do you think is the best??

I am looking at installing in a Passat 125 TDI MY08.

Greg Roles

14-09-2012, 07:06 PM

The one way PCV valve is only used for a return to sump, and this is NOT recommended, especially on a modern car. Sure I do it, but I'm accepting the possible risk.

The best hose is normal rubber 3/4" hose, as it;s cheap and does seem to be lasting much longer than expected. You just need adaptors to space it up to 1" / 25mm to suit the Provent, and I've also seen guys bond 3/4" inside 1" hose with specific loctite glue.

There WILL be full Provent kits being released in the next few months, at long bloody last. Pray my house sells for a fortune tomorrow, as that's basically funding the process!

Gigitt

15-09-2012, 05:40 PM

Flickr is crap for posting pics onto forums... use Photobucket.

I bought my Provent then fitted it... It is so much easier to put the provent into location and then you can see what works and not for routing the pipe work.

I pretty sure that position behind the drivers headlight will NOT work as the diesel filter is in the way.

Also the filter may not seem tall... but when you add a 3cm elbow to the bottom to redirect the colected oil... it adds to the overall height of the unit.

Note that routing any tubing around the back of the engine cover you must be careful as that is where all the turbo exhaust outlet/Dump pipe goes and if you have a 125TDI the DPF - and it gets hot back there.

sn809

15-09-2012, 11:49 PM

Hmm. Ok. Have ordered Provent tonight. I will try and see what works once I have it in my hands. Will get the tubes etc once position is decided. I am surprised at how limited photos are there with regards to the passat and any CCV filter installation. Most of them are pre 2004 on the net lol. All the new ones are for golf TDIs.

Greg Roles

16-09-2012, 11:59 AM

I will work on that, am overdue to do a proper Provent install article.

Golf TDI and Jetta / Passat TDI all virtually identical, Passat has the GT TDI / GTD engine in the TDI version, so the layout / space should be the same.

Gig is onto it, no way you could fit a Provent on the drivers side with a lot of relocation work.

sn809

16-09-2012, 02:45 PM

Thanks Greg and Gig. Took your advice and have thought of a different plan.

Has any one thought about moving the Air hose by twisting it to the right. It will make the pipe face towards the battery and move it to a horizontal location.

I know it is a low pressure system so not bothered about that but the temperatures in the surrounding and for the gasses it self is a bit of worry for me as I am going to do a fair bit of highway travel and want to do this install before I go.

What temp range is to be expected inside the system and out side as well.
The Ryco Defiant would be a very good hose to use as it is very flexible thin but reinforced enough not to collapse, as per their website

Tube:
Black, oil resistant synthetic rubber. (Nitrile).
Reinforcement:
Textile reinforcement with spiral wire to prevent collapsing.
Cover:
Black, oil resistant and abrasion resistant synthetic rubber.
Temperature Range:
From -40°C to +100°C (-40°F to +212°F).

And that is where the problem lies I am sure the temp is going to be a lot higher.

The ID is 25 mm for the tube you selected isnt the ID for provent 20mm.

There are a few more tubes I have looked at will get in touch and see if they do retail. Not wanting yo go with silicone till I get some specifically designed for temps and oil as there is degradation of normal silicone with the byproducts going into the engine.

How many bends will you have in your installation?
Keep me updated. I would like to know when you get the items.

How much did the clamp and tubing from bunning cost I intend to do the same. Did you have a look at the 3rd photo what do you think about the drain opening.

Gigitt

16-09-2012, 10:45 PM

sb809,

you will not be able to mount the Provent as in pic 3 from that bracket.
the bracket is light weight and will be bend, or be ripped off the fire wall... I also considered this position and it just will not work.
You also have the ABS unit below and you cannot have the provent touching the brake lines as it could damage them through vibrational wear/rubbing.

There is really only 2 places to mount the provent in a stock engine bay:
In front of the engine between the radiator, Oil FIlter and air intake
OR
where I mounted mine.

The only other option for an Easy install is to get yourself a new Air Intake - Like an APR Carbonio or ModShack, VWR, BMC type... Then you will have stacks of room

Seriouly wait till you have the provent in your hands. then start sticking into places and see if it will fit and if you can route the hoses.

sn809

16-09-2012, 11:11 PM

Thanks Gigs. What about turning the hose clockwise to face right. Do you think its doable??

Gigitt

17-09-2012, 07:19 AM

If you mean the 4in ain intake pipe that connects to turbo flange...
I think not. It is reallly not that flexible so the angles would be all wrong to connext back up.

The 1in metal pipe comming from behind the engine under the air intake is actually the EGR pipe from the exhaust (Post EGR Cooler)

No 25mm.

None hopefully. If the tube is too stiff then I'll put some in.

Tap less than $5, clamps around a dollar each.

I'm going to either put it where Gigitt has his, but because I have a tapped drain hose off the bottom, I'd like it to be somewhere more accessible. I think that with the right mount, I can mount it over/in front of my Oil Filter with little drama, it'd be cooler there and I'd be able to drain it easier.

Wow, compared to the photos this thing is huge Now I understand what you guys mean lol. I dont think I can find space in the front for this, I dont want to invest in a modified air intake at the moment either as I cannot afford it and to be honest have not looked into it at all. For all I know I may have to get the EGR valve cleaned or something due to the gunk already collected. So I have decided to follow Gigitt's plan but I cannot find a T plate or something similar does any one know where I can get it from. I know you did a DIY job but what have others used?

Also from what I can see in the photos, the drain is actually higher than the Provent?? Does that not cause a backup of fluid in the provent.

My Tap is higher... but the oil collects in the tube which is lower than the provent. The Tap is just to make it a closed system - Like I said I stick a Pella Oil extracting tube into the tap and it goes down like 30-40cm before it hits the collected oil.

You could route the tubing back down the firewall behind the gearbox and tie the tap up - but you will have to get under the car a bit to drain it - which I did not want to do - thats why I bought a Pella to do my Mk3 TDI Golf - but thats another thread and it does not suck the last 1lt on a Mk5 :(

I am thinking of getting a jumper cable and keeping that connected to the battery while I remove it and install the provent.

Sorry I missed your call, been a full on day, sitting here on the forums is a quick relaxation break. Best to respond publically for future readers. I don't do installs at this stage, I'm not a mechanic, and can't be liable for anything that may go wrong, however unlikely. Sure I can do it, but can't risk my fledgling company. I do plan to have a mechanic at the shop, and they can cover this sort of thing, and are qualified to do so. Happy to advise and show people what to do, but hands on other peoples cars myself, not so much. I'm heavily insured for tuning for instance, doubt an unqualified mecahnic would get mechanical cover!

Why are you moving the battery? Is it not easier to remove the intake tube where the space below is anyway? Some Torx screws and the whole top lifts off the airbox, and the MAF unbolts, one strong circle clamp and the part is out of the way....

sn809

20-09-2012, 02:59 PM

Yeah. Thanks and no dramas re the install. Hmmm I suppose it will be easier to move the Air vent pipe. So the question is does removing the filter cause problems?? I know petrol cars have no isssues but CNG (Overseas experience but a car is a car.) cars have to be retuned.

Transporter thanks for the tip re the battery removal. Have filed it away for future reference.

20-09-2012, 03:41 PM

Mate I'm returning a few calls now, will give you a bell, but removing the intake does not affect the car in any way - so long as you put it back together the same way. Heck mine has been off hundreds of times....and is no nothing like stock!

You do get more space to work in there when the battery is out... but Air intake is alot easier to pull out and put back in when you have only the car you are working on and have to get more from Bunnings to get it all to work! I made like 4 trips!

Tip: Put a clean rag in the intake pipes after you remove them - both the pipe you remove and the openeing you have to the engine... keeps the bugs and crap out... just remomber to pull rags out before refitting pipes.

Greg... I have an Idea for a Sump Return for the Provent and wanted your input.

Because I cannot use your method as my Provent is mounted lower than the oil filer, I have been toying with the idea of a drain directly to the sump.

1) Either a CNC'd 20mm spacer for the TEMP (or Oil Level sensor) that is on the back of the sump (125TDI) . Drill and Tap a barbed fitting on the side to attach a hose to and then the Provent one way valve... but this is the expensive option and don't know if it alter the sensors functionality.

Better option... I have just purchased some Fumoto Oil Drain Valves for my VW cars... now here is what I'm thinking.

2) Add the Long Fumoto Adapter (25mm) between sump and Fumoto valve... 25mm is enough space to drill and tap the adapter and add a brass barbed fitting here without compromising the threads of the Valve inside where the adapter screws in. Also probably braze or silver solder in place to handle the pressure so it does not leak. It is much lower than the Temp/Oil Level sensor.

To do it you 1st have to test fit the adapter and mark which side to drill the hole for the barbed fitting.

What are your thoughts on 2)

Cheers

[updates]
Did an oil change and took a good look under the car.
Installed the Fumoto oil valve but had to use an adapter due the sump plub being slightly resessed. Had to double copper washer the adapter so as to bring the valve tap to 11, oclock other wise it was sitting 6 o'clock and lower than the sump.

1) seems to be a temp sensor not a oil level sensor as it is at the botom rear of the sump

2) the oil gets mighty hot need to malke sure that the hose is capable of holding hot oil mixture.
also thought about brazing a copper pipe to the adapter to bring the hose mounting point above the oil level.
there seems to be plenty of room behind the sump... issues are clearence from engine movement and also keeping the pipes and hoses away from the exhaust which it nearly right above the sump plug.

Nope, it's total km buildup. Short trips can kill DP lifespan, oil / EGR buildup is a whole separate issue. It's basically like cholesterol for your intake, especially the inlet runners and ports.

By then it's too late to bother mate. Oil ash buildup is what kills the DPF and the PCV vapour / EGR soot builds up in the manifold, ports and bakes onto intake valves. Using a inlet "sea foam" type flush, that is one specific to diesels, is one option, but in my mind just ends up in your DPF. No way a genuine Provent 200 in the stock PCV system could be seen as a warranty killer, for the manufacturer Mann and Hummell build a vast majority of the plastic air boxes, inlet, manifold and filtration systems on euro cars, and apart from sucking in dirty air via an open drain tap, I can't think of a way it could cause harm. It is CE marked etc etc, just watch out for the China fakes, they DO cause problems.

Still your call, given what I'm about to do to the Yetis DPF system, I think my local dealer won't be too worried about the Provents!

Hi Greg, I have never owned a passenger diesel powered car and have ticked Diesel power for my next car. Been driving Diesels in the VW Golf 7, Tiguan, Skoda Octavia, Mazda CX5 and Ford Mondeo TDI Wagon and some others.

So any Diesel on my list and in general would benefit from a Provent?

I previously owned a highly modified WRX and made my own CatchCan for it with self draining to the sump.

So the Provent operates on the same principal of removing excess oil in the engine ventilation system?

Greg Roles

10-03-2015, 05:44 AM

Yep, but return to sump is not ideal in a diesel as you are already hammering your oil with soot and diesel blow by, so the Provent drain is better discarded. I ran a return to dump in the Golf, but did change the oil twice as much. This time I'm draining it off.

Copy that. I'll talk to my mate Graeme... or more likely, one of his sales guys. Haha.

Greg, just clarify - the catch can collects the sum gasses but how does the oil contaminate the EGR?.
I thought the exhaust gas was free of blowby oil which was a PCV issue.
In other words does the Provent stop oil somehow contaminating the EGR?. ....Does the PCV allow/direct oil vapour to the EGR..

The crankcase gasses contain an oil mist. Usually crank case gasses are returned into the inlet pre-turbo.

The EGR gasses are incorporated to the inlet air after the EGR valve, post turbo.

When the EGR is recirculating, the soot laden exhaust gas is mixed with oil laden crank case gasses and combine to deposit black carbon rich goo on the walls of the inlet after the EGR valve.

A provent or other catch can helps reduce the content of oil mist in the crank case gasses which in turn reduces the propensity of the EGR + Vent gasses to form goop.

Do you mean for a second time?.
Under what circumstances does it 'recirculate'?

No, I mean when it is operating. Valve open. It's nature is recirculating.... It recirculates exhaust gas through the engine.

Yeah, I get that, it's just the matter of why an oily atmosphere would not be kept separate from the regurgitation and, instead, allowed to foul the EGR.
It's the fact that it's claimed that the catch can helps keep the exhaust gas recirculating system absent of oil mist which should never have been the case ....or is there something obvious I've missed?

(on another forum I made the suggestion that a catch can could help keep the EGR free of oil contamination which resulted in the, in hindsight obvious, statement that the two systems were separate from each other, in that the oily mist is introduced downstream of the EGR therefore not relevant to 'it's' fouling)

Am I missing something?.

You are not missing anything. Both systems are separate and one affects the other.

The issue is not one or the other. It is the combination that together they create a sludge that stick to the inside of the EGR and intake and builds up to clog everything up.

You have to remove one or the other.

It is easy to remove the oil vapour from the PCV and also LEGAL.

Removing the EGR harder and illegal.

The oil most is not introduced downstream of the egr, its upstream

What!
So the PCV directs the unfiltered blowby directly into the EGR from the upstream end.
The EGR redirects some of the exhaust plus all of the oily blowby sump fumes back to the engine through the turbo for 'reprocessing'!!??
It's difficult for me to think there isn't a better system of dealing with two different systems...sump fumes and exhaust gasses separately.
No wonder there is a 'gumming' issue of both the turbo impeller and EGR plus inlet manifold as well.

Please carefully reread my answers. The egr introduces exhaust gas after the turbo. The pcv introduces crank case gasses pre turbo.

There's no gumming issue of turbo impellers. That really would be crazy.

The pcv gasses are not unfiltered on modern cars, but often there is not as much oil removed as could be with a higher capacity system (such as adding a prevent)

The aim is to prevent emission of hydrocarbons from the engine. Recycling the crank case gasses through the engine is an efficient method of dealing with that.
Recirculating exhaust gas happens only during specific circumstances, which the ECU controls ( there is an egr map just like a fuel map).

So what happens if we just let the EGR flap clog up (besides the ECU throwing a CEL)?
NOx emissions will increase but what else?

To me, who is struggling with this - I'm think the EGR contamination is strictly 'post combustion'.(?)

I'm a pre OBD old man and accessiblity aside and creaking joints, I'm simply not equipped to cope anymore.....they're both in warranty anyway.
BUT I'm fascinated by advances in design and tech.
Personally, I think we're in the last decade of 'reciprocating' engines and their expenses but one thing is certain, change is accelerating and there are going to be winners and losers.
