How Does A Oil Catch Can Work?

[AAARGH 33]

Hey guys,

I did a bit of searching around on the forums but couldn't get the answers I needed.So how exactly does an oil catch can set up work?

Although I have a very faint idea on how the pcv setup works (releases the blow-by gases from the crank case),I haven't understood the oil catch can set up.

So the questions I have on this set up are:

-Does it increase the performance of the engine?

- Is there any gain from it on a stock engine?

-What are the possibilitys in terms of plumbing and blocking off to accommodate this set up?

-If you are using the stock intake pipe,do you simply block the hole where the piping previously connected up to?

Thanks in advance.

Hey mate the way I understand it is that the catch can collects any oil that is getting thrown into the intake pipe. and lets just air go into the intake or vents the air to atmosphere depending on how it is all set up.

As for if there are any gains or performance on a stock engine i don`t think so. Some people may think there is but personally I see it more as trying to make your motor run better.

And with blocking off the intake i normally run mine with one pipe coming off of the cam cover into the can and then from the can run a hose back to the intake. It still works this way and gives you one less reason to be picked on by the jacks.

Easiest way is to get a good baffled one vented to atmosphere and run two hoses (one from each valve cover) directly to your catch can. Depending on the condition of your engine, it may pick up very little blow off or it might be quite a bit.

this is how i run mine... the intake is blocked off, both cam covers go to catch can, can vents to atmo and cam cover to plenum is left untouched

Isn't vent to atmo illegal? would the cops defect you or something?

So when you run the hoses from each cam cover to the catch can to vent to atmo what do you do with the intake hole?

it's illegal yes....

i use rubber stool feet from clark rubber and hose clamps.

works a treat and look neat.
