I am working on a crankcase evacuation setup on my Regal. It utilizes a LT1 electric air pump and a pair of check valves/breathers in the valve covers. I want a one way check valve to fit in the breather hole and I can mount my K&N breather atop the check vavle. This way I have normal breathing of the crankcase while driving, then when the boost comes on, the PCV's on the breathers will close and only allow the crankcase pressure to be sucked by the LT1 electric air pump.
My question: Someone suggested some 80's cars had BIG check valves on their emissions equipment. Anyone know of a PCV that will fit in the valve cover breather hole?
