      You would be able to locate the PCV hose in the following location: 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. 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. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
