How to Change a Silverado 5.3 PCV Valve

The Silverado is a full sized pickup truck designed and manufactured by General Motors and sold under the Chevrolet name brand. The Silverado comes equipped with different sized motors, including the V5300 5.3L V8 engine. The vehicle is equipped with a positive crankcase ventilation (PCV) valve. The valve has the primary responsibility of removing gases from the exhaust, to reduce pressure buildup in the engine crankcase. Replace the PCV valve at first sign of failure to ensure the vehicle passes an emissions test and runs efficiently.

Things You'll Need:

• Flathead screwdriver
• PCV valve
• Needle nose pliers

1. Park the Silverado on a level surface

Park the Silverado on a level surface. Allow the truck to cool down for a half hour before beginning any maintenance under the hood.

2. Open the hood of the Silverado and locate the PCV valve

Open the hood of the Silverado and locate the PCV valve on the driver side rear corner on top of the valve cover. The valve cover is positioned behind the spark plug distributors. The valve is connected to a thick hose and is seated in a rubber grommet.

3. Remove the hose from the valve by pulling gently

Remove the hose from the valve by pulling gently. A hose clamp may secure the hose in place; if so, use a flat head screwdriver and loosen the clamp.

4. Pull the PCV valve out of the rubber grommet

Pull the PCV valve out of the rubber grommet. Use a pair of needle nose pliers to grab the valve and pull out. Be careful not to damage the rubber grommet. Discard the old valve.

5. Insert the replacement valve into the rubber grommet

Insert the replacement valve into the rubber grommet. Push the valve down with your fingers until you hear it snap into place. Connect the hose to the valve by pushing it into place. If there was a hose clamp, tighten the hose clamp using a flat head screwdriver.

• I realize with my 04’ 5.3. I have to remove/replace the valve covers. Or remove and clean them! What a poor design!
