Where was the oil? On the electrode in the combustion chamber? Or was it on the top of the plug where the spark plug wire connects to it? If
the latter scenario is the case, then it's probably the spark plug tube
seals at the valve cover. These dry up and get compressed over time and then fail to seal. Try replacing these first and clean up any oil.
Recheck the plugs after a week or two. If there's still oil, then you
may need the lower spark plug tube seals.

These lower seals go between the cam towers and the cylinder head. If you wind up replacing these, then you should probably put in a new cam seal as well. Check the factory service manual for the proper torque specs on the cam tower bolts. It's also helpful to back off the valve adjustment screws until they're flush with the bottom of the rocker arms. This helps prevent the screws from catching on the top of the valve stems and bending a valve when you're putting the rocker arm assembly back on the head.

Rate this.

I have a toyota cressida gli 6 1989 ,has spark and fuel,motor swings but just wont start


Where had you checked spark first? Is the distributor turning? This can be checked by removing the distributor cap and making sure the shaft is turning as the engine cranks. Have you checked that there is spark at the plugs? The ignition coil could be weak and still produce some spark but not enough to start the engine. Be cautious of all rotating belts and pulleys around the engine while working under the hood.

Oil-leak on spark plugs


Oil leaking on the spark plugs is caused by a defective valve cover gasket, remove and replace the valve cover gaskets.

Oil is getting inside distributor cap, have new distributor on it . Its a 1989 Toyota Cressida


check you PCV system you are getting to much crankcase pressure and this is causing the oil in the distributor, if the PCV system is working then suspect to much blow-by from piston rings.

1989 tOYOTA CRESSIDA sAPRK PLUGS WELLS. OIL IN THE SPARK WELL


The 7MGE has 2 separate valve covers/gaskets with 8 screws holding each cover that will loosen over time.
Find the phillips screws holding on the covers and retighten snugly by hand do not overtighten!
Pull plug boots/wires by the boot not the wire and use paper towels or rags on a long screwdriver etc to absorb the oil from the wells.
Carefully clean plug boots with spray brake cleaner (avoid spraying anything but the boot) and let dry.
Apply 100% silicone grease to inner boot before reinstalling to allow future removal without damage.
If your engine is particularly dirty you may need to remove the covers first and clean all mating surfaces then reinstall.
