The Positive Crankcase Ventilation service begins by removing the ventilation valve sub-assembly followed by ventilation hose disconnection. Install the ventilation valve sub-assembly by applying Toyota Genuine Adhesive 1324 or Three Bond 1324 or equivalent to 2 or 3 threaded sections. The ventilation valve installation requires you to torque it to 27 N.m (275 kgf.cm, 20 ft.lbf). Finally, connect the ventilation hose.
