My engine doesn't have a breather on the valve covers. Should I install one (or two) and what are the benefits? (please pardon my ignorance - it's my first project car)

Valvecover breathers are MANDATORY for fresh gapless ring engines, like the TOTAL-SEAL rings.
Dual breathers are darn useful for a tired engine, capable of crankcase clouding blowby. Dual breathers seem darn practical compared to a corked, unvented, unevacuated crankcase...this one is moot because it will vent itself after the first exposure to enthusiastic acceleration. A popped dipstick is a clue of bigger things to come. A single Breather is darn pratical to complement the PCV system....now a source of ping inducement. Intriging alternative is a crankcase Evacuation system...keeps ping down while upping the relative piston push for power.

I've got edelbrock valve covers on my 400. The breathers have a rubber grommet that doesn't have any hole in it. My question is , am I supposed to put a hole in the grommett, cause I don't see what good they do if the rubber grommet plugs up the hole. i do have a pcv bvalve in the valley pan.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
