This guide was specifically written to assist owners of the 6th generation (1997, 1998, 1999, 2000, 2001, 2002 and 2003) General Motors Pontiac Grand Prix GTP in swapping out an old PCV valve with a new one.

Owners of other vehicles equipped with the GM 3800 Series II 3.8L V6 engine may also find these instructions helpful.

Some of these cars include the Buick Le Sabre, Park Avenue, Regal, Riviera, Chevy Camaro, Chevrolet Impala, Lumina, Monte Carlo, Olds Eighty-Eight, Oldsmobile Intrigue, LSS, Ninety-Eight, Pontiac Bonneville, Firebird, Holden Commodore, Statesman and Monaro.

PCV Valve Location
The PCV (Positive Crankcase Ventilation) is a one way valve that should be replaced regularly. Check your vehicle's owner's manual for the specific service schedule for your car. I've read widely varying owner opinions including that it should be changed each year or anywhere from every 15k to 60,000 miles.

The purpose of the PCV Valve is to re-route unburnt gasoline fumes back into the combustion chamber rather than being discarded on the street.

Some of the symptoms of a nearly clogged PCV include a rough idling engine, loss of power, oil burning, an oily air filter, decreased mpg, or blown seals.

I picked up the new Purolator PV892 part at a Pep Boys auto care store for about $3.00. The entire PCV Valve replacement procedure (including taking pictures for this page) took about 10 minutes.

A few other compatible PCV valves with their part numbers are as follows: ACDelco 214-2296, Fram FV299, ACDelco CV892C, Borg Warner PCV307, Wells PCV68 and Luber-finer PC68.

First gather up a 10mm socket or wrench, the new PCV valve, a pair of needle nose pliers, and a shop rag.

Locate the PCV valve cover by clicking on the picture above.

I marked the location with a green arrow and dots.

Loosen the two 10mm bolts slowly while keeping a finger on the cover so that the spring loaded PCV doesn't pop out.

Once you remove both bolts, gently pry off the cover.

If the valve seems stuck, use the needle nose pliers to pull it out.

I recommend buying the ACDelco 214-2296 PCV valve since it has excellent reviews on Amazon.

Then just replace the valve with the new part and be sure to replace the spring and any o-rings or rubber gaskets that may have been on the old part.
