Motor only leaks when running

[protechk5]

My 6.2 seems to only leak after its been running. Ive replace most major seals and such. Is that crank pressure release valve or whatever its called my problem?

The Crankcase Depression Valve only works when the engine is running. If you leak after the engine turns off, its not the CDV.

I would of said backwards rear main seal , but its not a 350 small block .

I think i said it wrong, it leaks only when its running. How much is the crankcase depression valve? Can you still get it at the dealership or GM partsonline?
