1998 Toyota Corolla Timing cover

1998 Toyota Corolla 4 cyl Automatic 114000 miles

My timing cover is leaking. The gasket has to be replaced. How do I do it?
Do you

Disconnect the negative battery cable. Wait at least 90 seconds once the cable is disconnected to hinder air bad deployment.
Remove the right front wheel and engine under covers.
Slightly jack up the engine on the right side to remove the RH engine mount. Inspect the mount and replace if necessary.
Remove all drive belts.
Remove the valve cover.
While retaining the crankshaft pulley, remove the pulley bolt. Extract the crankshaft pulley using a puller.
Unbolt all three timing belt covers from the engine.

Check that the timing belt gasket has no cracks or peeling. If the gasket is not reusable do the following:
Using a flat-bladed tool and gasket scraper, remove the old gasket material from the cover and mating area.
Thoroughly clean all components to remove all the loose material. Remove the backing paper from the new gasket and install the gasket evenly to the part of the cover shaded black in the illustration.
After installing the gasket, press down on it so it seats and the adhesive firmly sticks.
Install all three timing belt covers and tighten the bolts to 62 inch lbs. (7 Nm).
Install the new valve cover gasket and seal washers to the cylinder head cover.
Install the cylinder head cover to the cylinder head; secure with four cap nuts to 53 inch lbs. (6 Nm).
Install two PCV hoses to the valve cover; secure with hose clamps.
Attach the engine wiring harness to the valve cover, then install the engine wiring harness cover and secure to 53 inch lbs. (6 Nm).
Connect the wire and clamp to the alternator.
Install and adjust all the drive belts.
Install engine mount to body and secure but do not tighten fully. Tighten the following:
Mounting bracket-to-engine mount bolt to 47 ft. Lbs. (64 Nm)
Mounting bracket-to-engine mount nuts to 38 ft. Lbs. (52 Nm)
Engine mount-to-body bolt A to 19 ft. Lbs. (25 Nm)
Engine mount-to-body bolts B to 19 ft. Lbs. (25 Nm)
Engine mount-to-body bolt C to 19 ft. Lbs. (25 Nm), if equipped with cruise control.
Install the right engine undercover.
Install the right front wheel and lower the vehicle.
Connect the negative battery cable.
Start the engine and check the ignition timing. Inspect for leaks and check vehicle operation.
