Picked this one up from the Canadian GTD forum. Mann make an air/oil separator that has been used with success by lots of dieselers with blowby problems but it's expensive! Thing is with blowby, starting can still be OK as can oil consumption. (My 1.5 goes great, starts on the coldest Tassie mornings, and uses a litre of oil between changes.)
So, the racing guys with dry sump motors use this oil separator and it looks suitable for our situation. One of the GTD forum members has used it and reckons it's the duck's nuts.
Quote: "I have a 1.6td in an 86 suzuki samurai. It has a 1 notch head gasket, and hits 10lbs of boost.
I was plagued with oil leaks. Couldn't get them to stop after replacing gaskets many times.
We vented the crankcase, but tee'd it into the valve cover oil seperator line, and ran it before the turbo.
It sucked 1-1/2 quarts of oil out of it on 100 mile drive!
So after lots of head scratching, and realizing I don't want any of this blowby to go into the intake... I found this handy air/oil seperator from Summit. They use it for dry sump oil systems for race cars. It was cheap too. $29! "
