Why bother?--------IT can be proven in every single Corvette engine, from pre c4 to present, that if you rev it, positive pressure in the crankcase is produced.
This pushes crankcase vapor out the fresh air tube, into the manifold, where it condenses.
So now if the vapor that would normally be sucked into the engine and BURNED with the PCV system, reverses based on RPM and gets sucked in the engine through the OTHER SIDE of the PCV system, what is abnormal????
Allthebest, c4c5
so which is it?Correction to the myth of positive crankcase pressure: it does not exist. There is always a vacuum present of -1 to -9 mm. I have a meter on this in fact. Also, I have two catch cans installed, which for ME is a lifesaver.
