How to Put a PVC Valve in a 2001 Pontiac Grand Prix

A huge two-door coupe is like the 2,000 square-foot bathroom in a rock star's mansion: it's so pointless, it can't represent anything but the height of luxury. Like Bentley today, that's something that Pontiac understood back when it introduced the long, low and wide Grand Prix back in 1962. In the 1980s, the Grand Prix lost a bit of that delicious pointlessness, but gained entry into a wider market of buyers who were more interested in a practical-yet-sporty sedan than an over-the-top fashion statement.

Instructions

1

Locate the throttle body, the main air valve on the driver side of the engine, sitting between the top of the intake manifold and the plastic airbox intake tube. Next to the throttle body you'll find a rubber tube plugged into the intake manifold. Follow it to the front valve cover.

2

Disconnect the rubber tube from the fitting on the valve cover; this fitting is the PCV valve. Start the engine and place your thumb over the end of the tube. If you feel vacuum, proceed to the next step. If not, examine the engine closer for obstructions in the vacuum tube.

3

Shut the engine off. Grasp the PCV valve and carefully wiggle it up and out of the rubber grommet in the valve cover. Shake it; you should hear the check valve inside rattle. If not, replace the PCV valve. Lightly lubricate the rubber grommet with engine oil from inside the valve cover, plug the new PCV valve in and reconnect the vacuum tube.
