Thread: Preventing oil vapour entering the intercooler in a 300TDi

I'm more worried about the oil that gets into my fuel pump diaphragm, the waste gate actuator and boost sensor. All of which I have either cleaned out or replaced due to oil, plus my intake manifold was filthy with it going into pot 1. Having a clean air system is also a plus.

I have collected about 20ml of oil in about 2000km. Seems to be working very well.

20ml in 2000 k`s Sorry but many a Tdi with 20 + times more k`s with out any wis bang gizmo oil catcher still surviving well I think some people are a little over cautious with old engines

Aaargh come on VNx
That thread you linked is a joke
Anyone who installs a can with 1/4" fittings to an engine with 3/4" PCV piping deserves whatever happens....

As long as the PCV filtering you add flows better than OEM you will be fine.

86mud on my old 300 I simply welded some 25mm ally tubing over the existing PCV hole on the rocker cover and then drilled it out to 1"... Able to them plumb in a provent 200 with it supported only by the piping?

If I poke around the shed I might even have a 300 rocker cover I could mod for you if you want?

I modded my prevent 200 for install on my 300tdi
Have a look at previous post.

I'm glad you said it,it still supprises me how many people worry about pointless stuff and ignore the important. Pat
