Catch Can Install

sicksubie · #1 11-20-2007, 05:22 PM

I installed my Greddy catch can tonight. No issues at all but as I will explain I was thankful that the seller included his stock WRX hoses with the can.

I installed it where my battery used to be:

This is a piece of a stock WRX hose running up and connecting to a length of stock SVX hose

And this is a picture of the hoses. I plugged off the nipple on the pass side of the intake.

sicksubie, what is the purpose and benefit of this?

It is in line between the vent on each valve cover and the return nipples on the intake. This acts as a separator for the oily air that without it gets pushed back into the intake. This is why on a stock car you see oil gunk in the intake and throttle bodies. This is a great mod with even N/A cars. I will probably looking for another one for my red car now.

So it is not beneficial for your throttle body and intake valves to get oiled every now and then?

Looks nice BTW!

I was putting a lot of oil into the intake and that I guess is what happens when you go forced induction. However, I have noticed on N/A SVX's that they also get a significant amount up in the intake too. I am guessing that as the mileage goes up on a car the more oil will pass through those vents and get up into the intake.

Here is a pic of what I was dealing with before the catch can..

Holy crap, I never!

For what you are dealing with it looks like your catch can could use a oil return line on it. I'm not even being sarcastic this time. That is some serious oil misting on what appears to be a more than broken-in motor.

Motor only has 2500 or so miles at this point.... A return line eh? Hmmmmmmmmmm.... I may have to look into that.

Thought the mileage in your sig was a typo. Are you getting blow-by? What could be forcing all that oil up into the intake? Are the stock VC's missing a baffle or filter?

what about the other crank case vent that is under the intake manifold? In reality you still need to hook up that third vent to your catch can to keep yout butterflys completely clean. The one I'm referring to has two ports on it. The bottom port goes to the PCV valve on the bottom side of the intake manifold, and the top port goes up to the intake.

It is a stage 3 kit... There is no PCV valve..

nope..... 2508 actual mileage on a rebuilt with ECUtune internals, motor. Like I said earlier in the post forced induction motors are more prone to this sort of thing.
