Get it from the intake mani...

Re:Catch can...junk?
 

I built a catch-can from an empty WD-40 can. I fiberglassed in 3 nipples ( two on top, one on the bottom ), and then painted it like a barbershop pole, but using red and black instead of red and white...

I haven't using it since I haven't built a intake/air filter system for the turbo yet. The catch can needs vaccum, and never boost, which can only be had between the air filter and the turbo's compressor housing/intake.

If you tap into the manifold ( intake ), then you'll get a vaccum, until you hit boost, then you'd actually be forcing presurized air BACK INTO the valve cover/crank case, which is the oppisite of what a PVC/catch-can is designed to do.

could you use a check valve?

Re:Catch can...junk?
 

No, b/c then the presure coming outta the valve cover will have no place to go ( but out the valve cover gasket, out the oil pan gasket, or the piston rings ).

Re:Catch can...junk?
 

No, turn the check valve around the other way, so it will only allow vacuum in, but close under boost

Re:Catch can...junk?
 

good question green! But one of the guys at my old school had a crx and never did any type of catch can setup. what would be the results

Re:Catch can...junk?
 

The vlave cover still won't be able to breath under boost when it needs it the most.

Re:Catch can...junk?
 

Ok, I'll take the question the next step....what exactly is getting hurt inside the crankcase if I leave the stock PCV setup? I'm running 9psi around town and I have no oil on my cheesy little breather filter...sufice it to say, if I am shortening the life of the motor any more that I have to, I will do it.

hell i think i did the worst i made a catch can out of a use a/c compressor drier and ran some lines work good and the product on top i have done that it works but fills up quick

Does anybody know this?
