oil on plugs

rob madison · December 22nd, 2008, 03:25 PM

i have a 1998 cobra, my problem is on the driver side of the motor, my second and fourth slots have oil on the plugs. i noticed this when i changed the plugs. my question is would i come out cheaper getting a new motor, or getting mine worked on?

there oil from the internal (inside engine) or external (plug)? It really depends on how much money you got to spend. It will probably be cheaper getting it worked on if you can find a good shop that can take care of you. But I also have heard of some companies selling the stock short block for cheap (cant remember them though)

it would be cheaper just to rebuild what you have. correct me if im wrong but thats going to be rings most likely if you have oil on the spark plugs?

isnt that either a ring or a valve guide or sometin

wraitherx · December 22nd, 2008, 06:16 PM

can be either one.

If the oil is in the hole with the plugs, you need new gaskets, if it's on the bottom of the plug, you need other more costly things.

Be more specific on where the oil is exactly on the plugs. Does the electrode have oil on it or is the oil on the exterior of the plug?

Uh... didnt i already ask ^

but yeah you need to be a little more specific so that we can help.

the oil was on the exterior of the plug,(where the coils are) i think i probably need a gasket. I noticed a piece on the spark plug wire when i took it back off yesterday. A co-worker took a look at it, he said if theres not blue smoke coming out the pipes, then it may be a gasket.

you have a gasket leak. just for your FYI the driver side valve cover is a PITA to remove, just search and you will find.

If it's on the tip of the plug have fun getting your rings and/or valve seals replaced. Check thoroughly for blue smoke at high RPMs or even start up though. Some people lie to themselves about exhaust color. Have a friend check it out too. Motor is known for valve seals and with a decent mileage on your car a ring or two could be hurt.

If it's on the outside it's probably the gasket issue.
