Hey,

Anyone vented their crankcase straight to air with two filters? (both sides) If so any pics, thoughts, sizes etc?

My tune isnt reading off the MAF so not to bothered about that.

Goal is to lower crank pressure.

 

I ran a hose from both valve covers to under neath the car to dump fumes.

 

almost everyone vents to air. doesnt matter if its thru a catch can or not.

i use 3/4" lines.

 

cool, got two filters will vent them straight to air without catchcan.

 

jus FYI, the filters really collect the oil and drip onto whatever is below them. my frame rail is a mess

 

Lol so true.


If you use a check valve for catalytic converters (not sure where we found them) but you can use the vacuum of the ehxaust to suck out crank case evap. Definitely the cool way to do it. But with a vq you're gonna have to put it pretty far back to not foul up o2 sensors (vs a 2jz where every turbo aspect is better lmao)

 

Have you enlarged ID on valve cover pipes?

 

the covers are plastic, drill them out to whatver size you want. mine are -12AN
