Oil Burning on rebuilt motor

#1

I have a rebuilt 350 motor with a mild cam. It will burn oil at idle
with one pcv valve. If you put in 2 it dont burn oil. Perfect
compression. Wont do it above idle. What could this be?

#2

hmmm?that is strange. without the secondary pvc how is it breathing? do
you have a open breather or does it go to the air cleaner? does the
engine have alot of crankcase pressure?

I would check that all the valves got valve seals.
