It is located in the valve cover assembly on the front side of your engine, near the front of the driver’s side cylinder head.

Tools Needed for PCV Valve Replacement

Before you begin replacing your PCV valve, you will need to gather some tools. You will need a ratchet, socket set, flathead screwdriver, pliers, and possibly a gasket scraper or other cleaning tool. You may also need an oil filter wrench if you plan to replace it at this time. Make sure to have these items handy before beginning work on your vehicle.

Steps to Replace PCV Valve

Once you have all of your tools ready, follow these steps to safely and correctly replace your PCV valve:

• Disconnect the negative battery cable from the terminal.
• Drain any remaining oil from the engine by removing the oil drain plug.
• Unscrew and remove the oil filter.
• Remove the oil filler cap from the top of the valve cover.
• Unscrew and remove any screws that are holding down the valve cover.
• Carefully lift up and remove the old gasket from around the PCV valve.
• Using a gasket scraper or other cleaning tool, scrape off any remaining gasket material from around the area where you will install your new gasket.
• Apply a thin layer of sealant to both sides of your new gasket before installing it onto your vehicle.

.

. Position your new gasket onto your vehicle so that it lines up with all four corners of where you removed it from.

. Insert all screws back into place and tighten them down with a ratchet.

. Reinstall any other components that were removed during this process.

. Start up your engine and check for any leaks or other problems.

. Reconnect negative battery cable when finished.
