Toyota 12204-31040
PCV Valve

The installation of the Positive Crankcase Ventilation Valve for the 2AZ-FE emission control system requires Toyota genuine adhesive 1324 or three bond 1324 or its equivalent applied to 2 or 3 threads of the valve. The 22 mm deep socket wrench should be used to mount the ventilation valve at 19 Nm (194 kgf-cm, 14 ft-lbf) torque before adding the ventilation hose. Installation of the engine cover sub-assembly should follow the leak inspection procedure.

The first step of servicing the Positive Crankcase Ventilation Valve includes uninstalling the V-bank cover sub-assembly followed by disconnection of the ventilation hose from the valve. Proceed to take off the ventilation valve from its place. Install the ventilation valve by putting adhesive on 2 to 3 threads with Adhesive: Part No. 08833-00070, Three Bond 1324 or equivalent before torqueing it to 27 Nm (275 kgf.cm, 20 ft. lbs.). The installation process ends with connecting the ventilation hose to the ventilation valve followed by restoring the V-bank cover sub-assembly.
