Rubber Hose To PCV
This automotive maintenance DIY tutorial was specifically written to assist owners of the second generation (2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 or 2015) Toyota Tacoma pickup truck in checking or changing the PCV valve in the 1GR-FE 4.0 liter V6 motor.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Matrix, Prius, Camry, Corolla, Sienna, RAV4, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Hilux, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

A few compatible replacement PCV valves with their part numbers are as follows: Toyota 12204-31030, Purolator PV1090, Wells PCV141, Airtex 6P1019, Standard Motor Products # V408, Power Train Components PCV2389.

The tools needed to complete this procedure include a deep well 19mm socket, a 1/2" drive ratcheting wrench and possibly also a wobble extension bar and/or a universal swivel joint for better leverage.

Pinch Hose Clamp Tabs
Pull Off Rubber Hose
Vacuum Line Disconnected
The PCV valve is located near the right rear corner of the engine just above a spark plug ignition coil module.

Squeeze together the two metal tabs on the clamp before pulling the rubber hose straight off the nipple on the PCV valve.

PCV Valve Exposed
Loosen Counterclockwise
Spin Out Old Valve By Hand
Attach the deep well 19mm socket and 1/2" drive ratcheting wrench to the PCV valve.

You might need to use a universal swivel joint and/or a wobble extension bar to get a better grip on the old PCV valve.

Carefully loosen the old PCV valve by turning it counterclockwise.

Once the old valve is loose, pull off the socket and spin it out the rest of the way by hand.


Old Valve Removed
Socket Above Spark Plug
Spin In New PCV Valve
Since new PCV valves are so inexpensive, I would recommend just replacing it rather than bother cleaning the old one.

If the old PCV still makes a rattling sound when you shake it, the valve should still be good and may be re-used.

To clean the old valve, spray it with some carburetor (A.K.A. "carb") cleaner or an engine cleaning product such as Sea Foam.

I recommend buying the genuine OEM Toyota 12204-31030 PCV valve.

Spin in the new PCV valve in the clockwise direction by hand until it makes contact with the engine block.

Installing the PCV by hand will help prevent it from becoming cross threaded.

Tighten New Valve Clockwise
New Valve Installed
Rubber Vacuum Hose
Tighten the new PCV valve with the 19mm socket and 1/2" drive ratcheting wrench to just past hand tight or about 20 ft-lbs of torque.

Double check that the new valve is tight before moving on to the next step.

Push On PCV Hose
Hose Re-Attached
PCV Valve Replaced
Squeeze together the two tabs on the metal hose clamp before pushing the rubber vacuum line on to the nipple of the new PCV valve.

Double check that the rubber hose is securely attached to the new PCV valve.

Start the engine and listen for any strange sounds that might indicate a disconnected vacuum hose.

Be sure to record the PCV valve change in your truck's service records.
