Im about to wrap up this wrenchfest on the car and one of the last things im about to embark on is the crankcase evac.
I already tig welded the tubes into my exhaust. Im running 3" dual stainless with longtubes. Welded them in 8" behind the 02 sensors.
My plan is to run two catchcans (made from modified old a/c dryers) that hook up to the exhaust. From there, one side will hook up to the drivers front valvecover, and the other to an elbow at the factory PCV location which vents under the intake baffle.
Im considering using my unused 5/8 connection on my airbox, running through a checkvalve and into the passenger rear vent in the valvecover to supply filtered air in(so I dont suck air into the catchcans during acceleration), possibly through a regulator if needed. However, this is my first attempt at a crankcase evac system, and there is very little info out there on it.
Do I need fresh air in or no?
Are there higher quality (or more sensitive) checkvalves available other than mr gasket?
Should I keep both cans seperate or just run a large single?
Engine is a cammed 350, but the going thing Ive noticed is the PCV is rather inadequate...works fine at lower RPM as designed. Im trying to sort it out before I drop in the 427 in the next year or so.
I do plan on running a vacuum gauge on the crankcase.
