Catch Can INSTALLATION. The Final Debate.

Do you think it will be okay if my catch can does not have a breather on it? The vacuum will remain sealed.

the catch can has to vent somewhere or you are just plugging the hole in the valve cover.

Connect it back to the intake bubble as it should.

The vacuum comes from the intake side of the PCV system. The point of the catch can is to catch/condense the oil coming from the valve cover and stop it front getting back into the intake track and gumming up the intake/rear turbo...

Yep, just like I said in post #5.

Not if you run it inline with the hose. it will act the same as stock with the benefit of catching contaminants. Same goes for the the front.

yeah that is exactly what I ran.

The rear is the most important because it sends all the oil through your turbos and then through the intercooler piping.

Mikey, you could put the breather filter on the rear as Ray and others said and put your Catch can(since you already have one) inline the pcv hose, and have best of both worlds, Zero blowby entering your engine.

I still stand by adding a can inline the pcv hose. Alot of blowby comes out of the pcv valve to the lower intake, making its way to the combustion chamber. Thats just as important to me.

OP (and other) mentioned he is changing intake to blow thru with dejon and gm maft setup. He won't have the bubble to get back in line with.

So, what would you recommend to keep vacuum? Run line from catch can to rear turbo intake tubing? Add a barb to dejon/gm maft intake?

Edit ... I see Dejon preturbo intake tubing has a nipple in it...

As to add on from what Ray said. I think I will run it like this which is pretty much what forest also said.

RVC > Catch Can

Other Catch Can Port > Breather.

This will catch the oils and help my system breath like stock (as if you were using the stock pre-turbo pipes).

I am just gonna try to keep it as stock as I can since there is WAY too many opinions on what will mess up VSS and what will not.
