hey guys im back! I CHANGED my valve cover gasket, intake,dist, resealed oil sending unit, oil pan. and im still leaking oil. i was wonderong how a 350 pcv system is supposed to be hooked up. im thinking im gettin alot of pressure and its blowing out my gaskets. i hav an edelbrock performer intake and carb. i have the carb line in the front running to the driver side valve cover to a pcv valve, and the passenger with the chrome breather type. am i forgetting something?

 

Unless you have oil drooling out of the chrome breather, it isn't crankcase pressure. The pcv system sounds fine. The breather won't let it build any pressure.
I was hoping you meant to type "replaced" oil pressure sending unit.
The only thing to do is clean the the engine and put the car up on stands and run it to locate the leak.
And don't make Sofakingdom come in here and lecture you about the missing smog pump bolt.
Surely it's not that!....
