T4 Diesel timing belt kit

[vk2mad]

Does this kit include new idler and tensioner pulleys? For $360 I think it should. Jim

Who are you buying it from ?

Maybe ask them if it has everything?

[Umai Naa!!]

Agreed. Check, and are you doing both belts?

[vk2mad]

I had a service including a new t belt and injector pump belt. three weeks later the motor stopped. It has no compression on all cylinders. I am hoping it is something that the service provider did wrong as I suspect bent and smashed everything. the motor spins over so not seized.

Sorry mate, it sounds like your mechanic has really ****ed it up for you there. I would agree with your diagnosis.

Make sure your actions are above reproach and hopefully you'll get a good result (shame about the headache though).

Out of interest - I assume this is a 2.5 TDI?

[vk2mad]

Yes. 2.5 diesel auto. I am fortunate it did not go out the back of Qld. Went a Mooloolaba, nice spot to break down

I read somewhere on this forum about different types of diesel engines in relation to timing belt failures , on some models timing belt failure will not put pistons into valves as they are described as non interference engines . Others well bye bye engine .

To my knowledge all the diesels are interference engines. Some of the petrol engines may not be, but a guy on the Vortex forum with the 2.5 petrol engine ['93 from memory] had a pile up with his. He was able to reclaim his engine as there was only minor damage to some valves. On the diesels even the camshaft can break as well as valves, lifters etc.

I should have some idea by Thursday next week. Car still on Qld waiting transport. Should be home on Tuesday.

All the diesels are interference engines. The high compression ratio in a diesel means that there is almost no clearance at all between the piston crown and the surface of the head. On TDI's especially, as the combustion chamber is a pocket in the piston crown (which is not wide enough or placed for valves to poke into)
