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

Provent 200 is an option


Provent 200 Catch Can Filter Suits all 4X4's with Turbo Diesel Engines - www.westernfilters.net

I did this on the weekend to stop that from
Happening. Cost about 50 bucks and works really well. Just need to paint it and tap in a one way valve in the bottom and pipe it back to the sump.
Got it from Autopro and Masters.

This is one of those things I know that should be done but have never gotten around to it.
Thanks to this post I have spent most of the afternoon googling oil separators.
I have ordered a provent 200 and will make it fit.

Maybe you should spend $10.00 more on some hose clamps and some teflon tape aswell

Haha I have both but decided not to use clamps as the fit on the barbs is so firm clamps wouldn't add much (so much so that to get the hose off the barbs you have to cut it). Need to just silicone the barbs in. There is very little pressure (if any at all) to worry about it leaking. I'll play with it and see over time.

The Provent 200 seems the way to go.

The only issue I can see is fitting a hose connection to the rocker cover.

Most people remove the exiting breather canister, then get a flange made up with a hose barb

Is there an off the shelf item I can use?

I have read articles about the diastrous results of having fittings smaller than original with a consequent build up of pressure. Are yours big enough?

Yeah mine are 5/8 and the original is 3/4 but it's not much of a restriction. My mates one is all 3/4 hose for his td5. I'll keep an eye on leaks developing and crank case pressure build up. If it looks like it's causing a problem I'll upsize it.
I can't see it being a huge problem as air is being sucked through from before the turbo as well as being blown in by the crank case pressure.

What sort of disasters have you heard of?
