i bought a pcv valve for my 96 ss. is it located on the pass. side valve cover? I just bought the car and changed the oil and purchased a pcv valve for the car. When i removed the hose that goes to the valve cover nothing was there. Im stumped. do i just place the fat end of the pcv valve in the hole and connect the hose to the top of it.

The PCV valve is on the drivers side of the intake manifold. The hose for it goes from the front of the intake manifold through a 90 degree curved rubber hose to a metal pipe, to another rubber hose to the intake manifold. The hose you are referring to is the blowby gas/engine breather hose that runs from the passenger side intake manifold to the throttle body and has nothing to do with the PCV system. - Peter

Actually, it's an integral component of the PCV system. People have played w/ this one for years. Blowby introduced into the intake vs. unmetered air and invalid MAP readings.

Keep all vacuum fittings intact and/or upgraded. This includes the entire PCV circuit (both driver's and passenger side).

What DOES reduce passenger side PCV circuit oil/blowby is a chambered design breather which prevents oil from readily being introduced to the intake manifold and this:

GM part# 12572717


What the pic doesn't show is the "fixed orifice" design of this valve. Been using it recently, and it does just what it's supposed to do.
