View Full Version : Preventing oil vapour entering the intercooler in a 300TDi

Hi all
Ever since I installed my Allisport intercooler I have been concerned about the oil residue that builds up in the silicone hoses and then the small amount of oil sitting in the base of the intercooler.
Will one of these help to prevent this or is there an alternative?

Provent 200 is an option

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?

In all of my 340k kms with the 300tdi, I have never managed to get the cooler flushing liquid more than mildly dirty. Used to do it every 50k kms. Now it's like check the pipes and leave for another 100 :D. My take is if your intercooler is filling with oil something more than a provent is needed!

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

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 going down this route, i like the shiny bits but works on the same principle as the PVC version in Muds' OP.
