The other thing I'm wondering .....is it better to run PCV to the air cleaner so it evacuates at high rpm when pressure is building up? If I understand correctly the pcv to manifold vacuum is doing no evacuation at high rpm
You're right,, at some point the crankcase pressure will exceed vacuum,, that's where the breather comes in, and vents the excess crankcase pressure/vapors to the air cleaner,,
So the motor needs both parts to be a complete system,, the PCV to suck out the vapors at less than WOT,, and the vent to the A/Cleaner for excess pressure..
Didn't we cover this under the "Massive Oil Leak" thread..???
