How to Replace the PCV Valve in a Toyota Tundra

by Contributor

The positive crankcase ventilation (PCV) valve makes up an important part of your Toyota Tundra's ventilation system. Air flows through the valve in order to ensure that your engine does not build up too much pressure during operation. If your PCV valve needs replacing, you won't have a problem making the repair on your Toyota Tundra.

Test out your Toyota Tundra PCV valve prior to deciding to make the replacement. You'll find your Tundra's PCV valve on the cylinder head cover. Blow through the tubing to make sure air flows freely.

Purchase a PCV valve for your Toyota Tundra. You can purchase the standard PCV valve for Tundra models manufactured after 2000 on Auto Parts Warehouse.

Remove the PCV valve in order to make the replacement. First pull upwards and then separate the PCV valve from the attached vacuum hose.

Discard the old PCV valve. Take the new one and attach it to the vacuum hose. You're going to position the smaller end of the valve into the open end of the hose.

Locate the open grommet in the cylinder head cover of the Toyota Tundra. Press the other end of the PCV valve into the grommet in order to finish the replacement.


  • You should choose the original equipment replacement for your Toyota Tundra in order to extend the oil and engine life of your vehicle.
  • If you have difficulty finding the PCV valve on your Toyota Tundra, you can locate the large throttle body hose and follow it to its opening to find the PCV valve.
