Ok so I ordered the air filter, should be here by Thursday. So I was brainstorming, I wonder if I could utilize both vacuum sources? I keep the manifold source with the check valve, have a "T" in that line, that goes to the air filter on the turbo. So under idle, and part throttle cruise, it is pulling from manifold, as soon as it goes into boost, the check valve blocks, and the vacuum from the air filter keeps pulling through the catch can. This way, the crankcase would have a near seamless constant vacuum. Would this work????
My only concern would be, under manifold vacuum, would the source at the air filter, be a leak until the turbo is really drawing, or is there sufficient vacuum there all the time?

Any comments?

your making it confusing =)

I think your just asking for issues, cuz you have hoses coming from everywhere.

Why not just cap off all the manifold ports, and just run the lines from both valve covers to a catch can, and catch can to turbo inlet.

Then keep the breather on the 1 valvecover for a bit of added insurance.

should the catch can be vented when like this?

whats a good catch can to go with?

Here you go....2 catch cans..

Well it is 3 lines total. I have to run a new one from the air filter, so I was wondering if I should just "t" the line I have from the manifold. The only thing I am unsure about, is if under manifold vacuum, would it draw from the air filter fitting as a leak?
How much vacuum is there at the turbo filter at idle and part throttle? If you have it at the turbo filter only, will it only pull vacuum under boost? Which would be better then nothing, but I would think a constant draw would be nice.

how do you have those AN fittings in those stock covers, welded?

do you not have a vacuum source to the can?... why not?

I dont think there is any vacuum being pulled at idle. The vacuum only goes into effect when the turbo goes into boost, then it starts sucking like crazy from every direction.

I wouldn't think so either, so I wonder if it would act like a vacuum leak at the filter, until the turbo is spooling and creating vacuum there?

i made one using aluminum tubing and whatnot. but i bought from home depot a water air separator for an air compressor for $12 and 2 brass fittings. i odnt have a pic but it works Outrageously

Moroso has a 12 AN baffle that fits the factory hole with a little creativity....

BTW those are 2 drivers side covers....

Basically the hole has to be made a little bigger and the Moroso fitting has to be modified slightly..
