the "pvc" breather that I used was a mr. gasket one, the only one I could find for the twist on type, the engine DID have a breather on the left side valve cover on the left side of the motor. the pvc was on the right valve cover.
so @ idle ,when the engine is warm the intake was sending pressure into the right bank thur the pvc since there was no check valve in it? causing the popping in the right exhuast pipe?
