To remove and install cylinder head cover and gasket (16-valve engines only):
1.
Remove spark plug wire connectors. Remove the intake air boot from the throttle housing and remove the
small rubber hose between the intake air boot and the idle air valve.
2.
Disconnect the electrical connector for the charcoal canister control valve, and the large vacuum hose from
the back of the upper intake manifold.
3.
Remove the support bolt from the back of the upper intake manifold, then remove the five nuts and washers
that join the upper intake manifold to the lower intake manifold.
4.
Rotate the upper manifold up and away from the engine. Remove and label electrical connections or
vacuum hoses as required. Then secure the manifold out of the way.
5.
Remove the two inner bolts and the six outer bolts from the cover, and lift the cover from the cylinder head. If
necessary, use a soft hammer to loosen the cover. Remove the center gasket from the cylinder head or the
cover.
CAUTION-
Use care when removing a stuck gasket. Damage to either
surface will cause leaks. Use only a gasket removing tool
designed for the purpose.
6.
Installation is the reverse of removal. Torque the eight cover bolts to 10 Nm (87 in. lb.). Torque the five
manifold nuts and the manifold support bolt to 20 Nm (15 ft. lb.). Torque the support bolt last.
