Thread: Crank Case Ventilation fully explained. (Turbocharged edition.)

Whether or not that is a good setup really depends on the design of that catch can. If the bottom port is designed as an oil drain with a really tiny opening to drain oil, then it's not really a good idea to try to force pressure up through that little hole. If it is a large port on the bottom, then you should be in okay shape.

oil drain is on the bottom, planning to drill and tap the holes for vents

exellent thread...! my buddie used it for his non nissan to fully understand what i was trying to explain about the importance of crankcase ventilation.

sub'd

Could you guys please post a diagram for a roller rocker motor (doesnt have stock oil separator) running a blow thru setup with atmospheric bov?

I'm still planning on finishing this by adding many more diagrams and descriptions. I just have run into a lot of other delays.
FuLLah, I will be covering all that in due time, but it will take me a while. Sorry.

No worries Ben, I know it takes time to do the diagrams but if you have a chance to explain how it should be routed that would help me as well. Thanks.

FuLLah, leave the PCV valve side of things alone as always. The WOT side you can't really route into the intake because you are blow-through. Blow-through really limits your options. You need to either vent the WOT side to atmosphere (not ideal), suck it into the exhaust post turbo, do the emissions air pump thing, or figure something out that doesn't let any oil contaminate the MAF filament.

Blow-through is really killing you.

Whats up with that pic of the blue genitalia?? It would be nice if we could see actual pics of peoples modded catch cans/breather setups and after market catch cans

hey BenFenner, any progress on new diagrams and descriptions on ideal catch can setups.

i've been trying to research proper catch can set ups.. your reads have been very informative! =)
