PCV problem!
 
I know this has been beat to death but I’m having problems! Trying to build a clean motor. I have relocated oil fill tube to rear of intake and PCV to rear of v/c it has a baffle on inside. My problem is oil is trying to push out oil fill tube. Also does anyone know anything about breathers and oil fill in top rear of v/c?

You may want to search over on the Corvette forum. I’ve seen this discussion over there much more than here, the C!-C2 section. Lots of guys want to run the early Corvette script valve covers but use a late model black without draft tube provisions so there are more solutions.

I suspect that the downward angle and bend in the PCV hose by the transmission dipstick is creating a p-trap allowing oil mist and condensate to pool and restrict the vapor/fumes from the crank case to be sucked into the intake and then the pressure is pushing out the breather. Not sure what the baffle in the valve cover looks like either or if that could be restrictive too. Also, can the pcv valve operate properly on its side?

I like the look but not sure that it would work better than what GM engineered ? That double snout air cleaner is amazing !

I think that the way the PCV Valve has been relocated, it is defeating the functionality a little. While the relocation of the PCV makes for a clean look, but it may be contributing to your problem.
