    Is it the connector at end of your solenoid your talking about? Because you should be able to cut it off and relace it. Or is it the actual terminal on the solenoid that's bad?

    Oil on outside of plug only, says gasket or seal leak, above it somewhere, just need to look real close or clean engine in that area, then observe evey once in a while to trace it. That tells me also that the engine internally is not a problem right now anyway.

    As far as starting goes, have you tried starting with shifter in other gears? Can you hear a click anywhere, perhaps at a relay under hood, or under dash? Check all fuses inside & under hood? Double check the connections.

    Just to clarify, oil was on tip of spark plug that came out of the hole, not on the outside of the plug, where wire goes? If on tip, was the engine not running rough, (missing) ?

For the oil it seems like head gaskets need replacing. As far as the electrical issue, sound like you may have a damaged wire from the ignition to the starter, I would try to trace the current to all electrical components; battery, starter alternator and see if you can find the area of the bad wire.

Oil leaking on spark plug


If the spark plug is oil fouled, you either have leaking valve seals, or bad piston rings. Bad rings would be accompanied by excessive blow-by. With the engine running, remove your oil filler cap. If there is air pulsing out of the filler tube, it your rings. If not, it is your valve seals.

Oil in most of my spark plug ports!


The fault is due to the valve cover gasket passing oil into the spark plug wells. There are circular seals under the valve cover around each spark plug well opening. These spark plug well seals come with the valve cover gasket set.

Chevy Prizm or Toyota Corolla 2000 valve cover gasket problem? Right after oil change, engine check light came on & car started smoking & losing oil. I took out all 4 spark plugs: they were in very...


The valve cover gasket isn't hard to change. Oil on the plugs indicates a more serious problem. Smoke from the exhaust would be from rings, rich mixture, worn valve guides. It may be that the engine is overfull (that would show on the stick). Oil loss from a leaking gasket would smoke under the hood and leave oil on the engine and the ground.

Oil where spark plug coil is


you have a bad valve cover gasket/ spark plug o-ring i assume the plug is set in the head with valve cover above it since there is oil in the cover gaskets and o rings are used to seal in oil remove and replace gaskets be sure to find the right torque spec for the cover bolts also remember to start with the center bolts and work your way evenly to the outside

I have an oil leak in a spark plug chamber how do is fix it


depends where the oil came from.of it has leaked down from a valve cover gasket,that is not hard to fix.if it a leaking valve seal that is expensive and if the head gasket is leaking,expensive.look at the outside edge of the valve cover,and check the edge for oil.if there is alot of oil,by the time the plug is unscrewed oil can go inside.the oil would burn off,so if there is oil inside it is dripping down probably from a valve seal.take off the valve cover and inspect the seals they are probably no good.there are 2 seal sets,one is in the valve cover,and that results in oil on the outside of the plug,and the actual valve seal which results in oil in the inside of the engine.

2001 jaguar s-type 4.0 oil in spark plug area


Hi bravo956
i also have the same problem regarding the oil leak. this is due to the spark plug gasket leaking and you will need to replace them. they are circular gaskets about 1.5 inches across that fit to the underside of the rocker covers and prevent oil from seeping down the long spark plug hole. when i investigated my leak i assumed it was just the rocker cover gasket that was leaking but once everything was removed it is obvious.

Spark plugs


Who ever told you it was the Valve cover gaskets was correct. On the valve cover gasket around where the spark plug goes down though the head there is a seal made onto the valve cover gasket called the spark plug well seals. when replacing the valve cover gasket it will come with these seals and it will take care of your oil leaking into spark plug holes. Hope this has helped and if you need anymore assistance I would love to help.
