Rewski Posted February 2, 2008 Share Posted February 2, 2008 I changed my spark plugs yesterday, along with a lot of other things, cause my car just hit 200k miles. I have never had a car that help oil on the spark plugs. I doubt its a good thing, but why is it happening, and is a terribly bad thing? Thanks in advance.

James Matteu Posted February 3, 2008 Share Posted February 3, 2008 Sorry, I got nothing. The manual only says that oil on the plugs falls under the catagory of "fouled plugs", and the reason given is "oil in the combustion chamber." I know, that doesn't answer any questions, but it's all I got. When I had this same problem, it was a bad valve seal on #3 in my 1987 Honda CRX DX, but I never fixed it and sold the car firing on 3 cylinders. That I assume is the ulitmate fate of your engine if you do nothing. Eventually, the plug will foul too quickly to make sufficient spark and the cylinder will go dead. FYI, you can drive (8 months in my case) on 3 cylinders, though people will hate you in traffic. Link to comment Share on other sites More sharing options...
Hatch92 Posted February 3, 2008 Share Posted February 3, 2008 could be rings, a dropped vavle, valve stem seal, ect. Link to comment Share on other sites More sharing options...

Hatch92 Posted February 3, 2008 Share Posted February 3, 2008 valve cover gasket? Link to comment Share on other sites More sharing options...
toyota7015 Posted February 4, 2008 Share Posted February 4, 2008 It is most likely your head gasket, with 200k on that engine, and I am sure its not a easy mileage, that head gasket will give in about that time, might want to take it to mech.

Kegger Posted February 4, 2008 Share Posted February 4, 2008 Here's the breakdown, simple style, for ya'll.... Oil on top of the plugs.... Bad valve cover gasket. Cheap and easy to replace. Oil on the electrode.... Most likely bad valve stem seals. But could also be bad rings. Both are cheap but not so easy to replace. Link to comment Share on other sites More sharing options...
Pyrorocketeer Posted February 4, 2008 Share Posted February 4, 2008 you had wet oil on the electrode of the plug? Sometimes oil gets into the spark plug holes in the valve cover, and will get on the plug when you take it out. The valve cover can leak around these holes every now and again, and leak a little down by the plug. Link to comment Share on other sites More sharing options...

James Matteu Posted February 6, 2008 Share Posted February 6, 2008 Why do we belabor the point, the OP is obviously disinterested, we laid out some possible senarios, end of story. Are the Accord owners on this forum so knowledgable that we have nothing to ask of each other? Link to comment Share on other sites More sharing options...
