A: The installation of the Positive Crankcase Ventilation Valve for the 2AZ-FE emission control system requires users to coat 2 or 3 threads of the ventilation valve with Part No. 08833-00070, THREE BOND 1342 or an equivalent adhesive. A 22 mm deep socket wrench should be used to place the ventilation valve while tightening it to 19 Nm (194 kgf-cm, 14 ft-lbf). Place the No. 1 engine cover sub-assembly afterward to complete the process and conduct engine oil leak inspection.
A: The first step to remove the Positive Crankcase Ventilation Valve requires complete fuel system pressure discharge. Begin the process by detaching the negative battery cable before taking out both left and right engine under covers. The first step includes draining engine coolant then uninstalling the No. 2 cylinder head cover. First detach the air cleaner cap sub-assembly with its attached hose before separating the engine wire harness. Remove the harness bracket before taking off the No. 1 fuel vapor feed hose and No. 1 vacuum transmitting hose. The vacuum hose removal process requires the fuel pipe clamp removal and disconnection of the fuel tube sub-assembly. The technician must first remove the fuel delivery pipe sub-assembly followed by the sequence of removing the No.1 delivery pipe spacer then the injector vibration isolator. Guests should remove the starter assembly and the oil cooler tube for Automatic Transaxle use alongside the transmission oil level gauge sub-assembly for Automatic Transaxle. The technician must begin by disconnecting the ventilation valve sub-assembly only after removing both the engine oil level dipstick and the intake manifold and the ventilation hose.
A: The Positive Crankcase Ventilation Valve service requires users to first remove the No. 2 cylinder head cover before separating the ventilation hose from the ventilation valve. After that disconnect the ventilation valve which needs to be taken out of position. Install the ventilation valve by using 2 or 3 threads of Adhesive: Part No. 08833-00070 or THREE BOND 1324 or an equivalent brand and tighten it to 27 N.m (275 kgf.cm, 20 ft.lbf). First install the No. 2 cylinder head cover followed by connecting the ventilation hose to the ventilation valve and ending with the reinstallation of the No. 2 cylinder head cover.
