PVC upgrade or inefficient? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello all,

New motor and yet another oil drip. The motor is fresh,5.7 negligible blow by.

I now have drip coming from the driver rear oil pan area. (not above) Every Chevy i have owned has its drip and I can't stand it.

Anyway,, I am going to pull and investigate. My feeling is I am still generating internal pressure that the PCV can not deal with at highway speeds. Are the TBI setups just not great at recovery? Should I add or upgrade the system? Is it the crank slinging oil on that spot?

Any insight would be great.

On my performance motors I just run two breathers to the air cleaner and never had a problem, those motors have much more blow by at 6,000 than my TBI
