Ok, I know that I have a leaky valve cover gasket now. When I checked my sparkplugs last night, i only checked the first two and they were dry. thanks by the way to those who helped out with the picture of the spark plug i posted yesterday. I've read that a leaky valve cover gasket isn't a big deal and that it's a pretty common occurance to have a little oil in the hole that leads to your spark plug. However, and I'm not sure that this is unusual, I found some oil in the last hole (cyl. 6) and the oil had seeped down onto the spark plug itself. Could this be one attribute to why i'm running rich?
Thanks.
Ramy

PS: I'm trying to get over 100 posts this weekend. ;-)

you should have no oil in any of your spark plug sockets.. whoever said a little is okay is a damn moron. You SHOULD HAVE NO OIL in or on your spark plugs. From what I understand, this doesn't attribute to why you're running rich. Running "rich" means too much gas I thought is what the term meant.

So why is it so bad to have oil in the spark plug well?

If the oil does not enter the combustion chamber, is there any harm? Sure when you change them, the oil will leak in. It also indicates a bad seal around the sparkplugs, but it doesn't seem to be the worst thing.

Thanks

Yes, this could be one reason to why you are running rich, since oil in this area can lead to the electricity not reaching the spark plug, and therefor no spark will ignite in that combustion chamber. if that happens, you will run rich since the ECU tries to correct this error !
