ProVent HP200 Oil Catch Cans

[Chip It Senior Member Find all posts View Profile Close Chip It]

its not going to effect warranty. No way it will damage anything.

The ProVent Style Catch Can is VERY different to other catch cans. The principle is the same but the ProVent HP200 is streets ahead of the opposition.

It has 2 relief valves. (some types have none). One is situated one the inlet port, the other on the outlet ports.

The small diameter of inlet / outlet connections to the can are problematic to modern hi compressions engines

Example 1

Example 2

Example 3

Example 4

Brogers I think we are going to get some pics soon as others have mentioned.

Cheers

Hello can you please tell me what the purpose of this is please? I understand the ruff basic's but do modern 4WD have a lot of oil coming out of the rocker covers?
Thank you

Got mine thanks Robert.

YES. they have a lot of blow by. Just take off your PCV tube from the rocker cover and go for a hard drive. You will be cleaning oil off the guard for hours. Also, those that have the Oil Catch Can will tell you how much oil they are draining from the can every 2 months.

Hope this helps

Chip IT, Thank you for your reply. I did not realise this was an issue on newer engines. Thank you for sharing.
I will look at procuring on of these for my Prado. early next year as I am not driving it yet.

no probs. if it is over say 60K kms it would pay to get the manifold removed cleaned and then put back on with the catch can. it will stay clean then. In fact, I will throw in a EGR Blanking plate to stop 85% of the flow ... less soot and heat in the intake the better as well. remind me

Chip IT, Thank you very much for your offer and sharing of your knowledge. It is very much appreciated.

Hi guys,

just wanted to clarify something... The oil catch can collects blow by from the rocker cover before it enters the air intake, therefore reducing build up in the intake manifold.

The EGR blanking plate blocks off a totally separate system which is essentially a small amount of exhaust that is recirculated into the intake manifold, adding to the build-up of unnecessary crap.

If my understanding is correct, which of these two systems is more likely to foul the intake manifold? Or is it an even split between the two?

A few things to consider.

Oil going into the intake

- pools in intercooler.
- coats intake with oil.
- enters combustion chamber and lowers octane / cetane. Low quality fuels (lower than minimum engine requirements) can cause less than optimal engine operation and may accelerate engine oil degradation.


EGR going into the intake
- up to 400 degrees Cel gasses going into the intake manifold. We are trying to reduce IATs with intercoolers and snorkels and this is doing the opposite.
- soot going into the manifold and then into the combustion chamber .
- displaces oxygen rich air in the combustion chamber lessening the combustibility of the mixture.
- causes black smoke.

When combined in the intake manifold the hot gasses (from EGR) cooks the oil from the PCV. If you remove the heat or the oil you stop the carboning of the intake manifold. If you remove both it is best for tackling the other issues stated.

If left to do its own thing soon the intake manifold clogs up to the point where the engine cannot breathe this causes black smoke and poor engine performance.

When building hi - performance cars most engine builders will have huge intake plenums which adds power. Going the opposite way is very counter productive and over time that's what the stock systems will cause.

A good article on manifold volumes and volumetric efficiency is HERE

Fitted up my ProVent today.. Looks good especially being constructed of ABS style plastic. Looks like it should be there... Need to construct a more descreet bracket...
