PCV Valve - LT-1 ????
Does it have one?
My oil leak has returned and one of the books said it might be caused by a clogged PCV. My service manual does not mention the PCV valve.
If it doesn't have one, is there something else that does the same thing?

You did not mention where the leak is at.PCV blockage will increase manifold pressure but most LT1 leaks are caused by the the crappy intake sealing in the front and rear of the intake.If that is where it is you will have to pull it and fix it.
