Re: Crankcase Pressure
Secondary air injection, and as Glenn pointed out, not legal for stock.

Re: Crankcase Pressure
I only have one breather on the passenger side of my 5.0 and no breather on the driver side valve cover. Difficult to get anything to fit on drivers side valve cover because upper plenum is in the way. I have tried open breather and have tried connecting it to the throttle body like factory. I also have the PCV valve coming out the back of the block and have tried sending that to the throttle body, sending it to the upper plenum, and just plain blocking it off. I still haven't figured out the best scenario for a stocker and I still burn some oil occasionally. Leakdown shows up fine. At the risk of sounding like a fool, are you supposed to block off PCV when you run breathers or can you run breathers along with pcv? I'm thinking that sending unmetered air back into an EFI system without the computer knowing may not be as good as a Carb system.

Re: Crankcase Pressure
PCV system always has a way to breathe. it pulls fresh air in thru the breather as it pulls fumes/pressure out of the engine into the manifold/plenum. Factory the breather tube goes to the air filter so it always gets clean air.

Re: Crankcase Pressure
Joe - That would be assuming one would want/allow the oil to drain back directly over the crankshaft.

Re: Crankcase Pressure
I'm no expert for sure, but I also don't have any Dart blocks lying about. It's my understanding that the Dart blocks oil differently and likely less oil up top to contend with. Using these old GM blocks my solution just seems to make sense to me.

Re: Crankcase Pressure
Ok i'm assuming a header vac system isn't legal in stock either since no one has mentioned it? and it would seem a obvious answer.
