---> one way valce--->pvc--->catch can with breather---->intake


will my pvc then be compatible with boost?? Will i still blow my dipstick out?? Crankcase pressure??

PCV. You'll probably need to at least vent the valvecover to keep the dipstick in place if you're having that problem.

if you were air would you rather flow through an engine or an air filter? air is going to take the path of least resistance.
you are likely not making use of the first three components and air is just going from air filter to intake.

get a can without an air filter, then you are talking. and put an air filter on the opposite side of the engine

I dont see how that would work... Hes still tapping into the intake, under boost, it wont be pulling a vacume, but pressurizing the PCV to the one way valve.

using the intake is fine, thats the whole point of the valve... keeping the pressure from backing into the crankcase.

but dont you want to try to pull vacume under boost (like running the PCV to the inlet side of turbo) or is the point, when under boost, just provide a way for the pressure to escape (with the breathers in the VCs)?

MIGHTYMOUSE

those are separate things; you can do one or both

appropriate breathing is absolutely necessary. vacuum is a bonus.

recircing the hot gas is pointless and only done for emissions.

pcv->catch can->breather.

Whats the point of the PVC when you already have a one way check valve?

Hooking your intake vacuum to that can w/ a breather is basically just creating a vacuum leak.
If you were to use a can without a breather, it would do the job better by actually getting vacuum to the crankcase. Then you'd need to do like mighty mouse did and provide another one way check valve to let pressure from blow-by to escape when under boost. That second valve would not allow air to enter, only let the gases escape.
If your running a catch can, thats the route to go. But, if your just gonna let it vent to atmosphere all the time its pointless to run anything more than a pair of valve cover breathers.

one-way valve --> catch can --> intake
ALONG with
one-way valve on other valve cover.

OR
Two Breather Filters ONLY
Anything else is pretty much pointless if you ask me.

My pcv is gone and I just run breathers. Plenty of factory machining in the block (pushrod, lifter holes) to let the pressure equalize internally side to side.

Screw the dinky little pcv line, plus now you won't have oil in your intake. I don't have any oil issues anymore after the pcv/catch can has been completely removed.

As a bonus, notice how much clutter is gone (pcv) in the left sig picture below?

and i am good to go for boost....no breathers required
