the pcv valve is located on the passenger side of the upper intake plenum there may be a plastic cover on the plenum . The black plasic cover must be twisted to the left (this may take a little bit of muscle), anyways once you remove this cap be careful not to lose the spring and O ring. The pcv valve may have to be removed with a pair of needle nose pliers.

There are two valves on the air conditioner on a 2000 Pontiac Bonneville. Attach the hose that fits the refrigerant and fill that side.

By now I'm sure you've found the answer. But a Pontiac engine does not have adjustable valves. You simply torque them down to 20 foot pounds.

A 2004 Pontiac Montana has an interference engine with very tight tolerances. These engines will suffer catastrophic failure if the valves and pistons are not in perfect sync.

Yes. When the chain breaks it will bend valves. I had 4 bent exhaust.
