1993 Pontiac Grand Am Question: how hard is it to change pcv valve
Answer #1Oakman August 28, 2009, 13:03Master
As I recall the PCV valve is quite difficult to replace on the V6 engine in your 1993 Pontiac Grand Am. If you are having no problems with your PCV system I would recommend not replacing the valve. Considering the age of your vehicle if you do decide to replace the valve it may be a good idea to have the rubber grommet and vacuum hose that attach to the valve as the old ones could be hard and brittle after all these years. The grommet goes into the base of the intake manifold and the short vacuum hose connects the valve to the vacuum side of the intake.

It's under the Alternator on the manifold. if you are a female with small hands easy fix.
