Catch can install question
#22
Best solution is to close the 2 holes the one on the plenum and the one on the intake, and put a catch tank with a T on one side and vented to Atmosphere on the other side, route the T to the PCV and the other side of the T to the driver`s side Valve Cover and then tadaaaaa you got oil :P

By the way, the APS one way valve? What does it do?

muzzy,
there is a crossover tube between the valve covers already. It runs from cover to cover, right in front of the intake manifold.

I have this setup, with a breather filter on the left valve cover. I holed a piston at the track, massive blowby. The catchcan filled with oil instantly, also blew a lot of oil past the plug wire openings in the right valve cover. ZERO OIL CAME OUT OF THE LEFT SIDE BREATHER FILTER.

If you do that you're going to be venting boost to atmosphere which I'm pretty sure you don't want to do.
Seems like running the can between the PCV and the manifold and installing a breather filter on the driver's side valve cover is the best FI solution.

Number 1 the driver's side vent doesn't have a one-way valve so you'll be pressurizing the crank that valve cover when you're in boost.
Number 2 from what he was saying it seems like he plans on venting the whole catch can setup to atmosphere in which case he'd lose boost via the intake manifold port.

Best would be to probably vent the catch can to atmosphere and plug up the plenum port to avoid the leak, but as mentioned you would get the fumes in the engine bay.
