It's pulling air in?

Install a breather instead of the cap, either the PCV is plugged or you have a major problem.

Sounds like the PCV is not functioning correctly, verify that you have it installed in the correct orientation. I assume that this is "at idle", Gonna guess that the PCV is stuck in the open position, at ilde the vacum generated should move the PCV to the closed position. At WOT the lack of vacum will allow the PCV to open which evacuates the crankcase gasses. If you find that this is not the case, maybe you have an intake gasket that did not seat well that is allowing one of the runners to pull air from the crankcase into the intake tract.

pulled the intake,replaced all the gaskets,replaced pcv for the third time and it lasted about a day and back to the same ol thing it runs as good as always did just builds vac on idle after a few seconds.I give up on the car and am parting out if anyone needs parts there up for grabs stripping everything at this time
