Exhaust Valve

Beginning the installation of the 2AZ-FE engine cylinder head cover assembly requires removal of outdated packing material and subsequent application of seal packing at specific locations using Toyota Genuine Adhesive 1344, Three Bond 1344 or an equivalent. The seal packing procedure requires the cylinder head cover to be installed within 5 minutes of application while engine start-up must wait for at least 2 hours. Security of the cylinder head cover requires 8 bolts combined with 2 nuts that should be tightened to specified torque values- 11 Nm (110 kgf-cm, 8 ft-lbf) for the bolts and 14 Nm (143 kgf-cm, 10 ft-lbf) for the nuts. The installation of the spark plug requires a torque of 19 Nm (194 kgf-cm, 14 ft-lbf) before moving on to put the front wheel RH and checking for oil leaks.

You need to remove both RH front wheels and RH front fender apron seal to start the valve clearance service on the 2AZ-FE engine. After disconnecting the engine No.1 cover sub-assembly you can proceed to release the spark plug socket and move on to removing the ventilation hose and ventilation hose No.2. Pull out the bolt from engine wire then detach its harness clamp to take down the cylinder head cover assembly. Uninstall the 8 bolts and 2 nuts along with the cover and its gasket for removal. Use your crankshaft pulley key to align the No.1 cylinder's top dead center position when its timing chain cover mark is at 0. Also normalize the camshaft camshaft timing gear and sprocket rotation with their respective bearing caps No.1 and No.2.
