Re: Dual PCV values...why didnt it work right?
Because that's not how a PCV system works. Fresh air goes in one side, circulates through the crankcase picking up blowby gasses, and then gets sucked out through the PCV valve and burned off in the engine. With two PCV valves connected to vacuum, you're just putting the crankcase under vacuum all the time and not accomplishing much of anything.
