How do you change valve cover gaskets on a 1999 Grand Prix?

The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Oohlalajameshunt, reiterate the answer of this statement. I recently just changed a 6 cylinder 1998 Grand Prix 3.8 valve cover gasket. I started at around 8:30 and finished around 2:30 pm, it could have been earlier but performing the repair myself took some time. It involves removing the alternator, serpentine belt, spark plugs, (make sure you number the plugs) check your wires for corrosion, so that you replace them as your replacing your valve cover gaskets. removing the coil rack and brakets also involved in replacing your gaskets. Called pep boys and they wanted 387.66 for the repair. Send me a picture of your engine and I'll resend you a work work picture repair guide. send response to
