Re: Oil Leak Possible Rear Main??
Sorry for the delay, just make sure the breather is not clogged, pull it and see if you can blow through it. Also make sure where the breather goes in the engine is clear too, pull the breather and run the engine, you should see and feel crankcase gasses exiting.
You could always add a pcv system. Pcv valve in one valve cover gromet to carb base or intake manifold and a breather in the other valve cover. It uses engine vacuum to pull gasses from crankcase into intake manifold to be re burnt in combustion chamber.
What year engine do you have?
67 Camaro 350
M20 4spd console,
8.5, 30 spline Eaton posi 373
