If you see any oil leaks between your Toyota Corolla’s cylinder head and its cover, it means that the gasket between the two parts is shot and you need to replace it.
The job is not that easy because of the amount of parts you need to take off before reaching the actual gasket. So if you’ve decided to do it yourself, take a day off and full toolbox before you start. Here are the main steps:
Leave the engine cool off before starting the job
Disconnect the battery
Remove the engine cover by unscrewing the bolts on top
Disconnect the electrical wires from all the ignition coils
Remove the bolts and take out the ignition coils
Remove the ignition coils support
Disconnect the two hoses connected to the valve cover
Unscrew the 8 bolts fixing the cover to the cylinder head
Lift the cover and take the worn gasket out
Put the new gasket in and carefully bolt down the cover again
Mount all the parts back just as you took them out.
