pcv valve or not.. hm

superbean · April 26th, 2009, 02:34 AM

On my current setup, I have two breather filters and a pcv valve running to the carb..

Since my valve covers are cheap chrome ones and are leaking, I would like to put a stock set of h.o. valve covers on it..

But the stock valve cover doesn't have a pcv setup, just a straight hose.

Think it will matter if I don't run a pcv? Not like my car is going to idle worth a shit anyway lol

Breathers + PCV = vacuum leak

You need to run some sort of crank case evac whether it be a PCV or breathers.

So either cap off the large vac port on the carb and run breathers or run sealed valve covers with a pcv valve correct?
