Oil on sparkplugs.

[slideways21]

soo i receently changed my sparkplugs and i noticed that my 4th sparkplug closes to the firewall has alot of oil, there first 3 are fine except the 4th one.. Whats wrong with it and what will this cause?

check the seal under the valve cover it could not be seating right or it could be pinched

What he said. Maybe it's time for a new valve cover gasket kit.

Where exactly was the oil? On the electrode or in the spot where the coilpack connects and the socket goes in?

Also do a compression check. The 4th cylinder always runs leaner than the other cylinders, and the rings may have gone bad there.

im gonna change my head gasket and valve cover gasket. The oil was all over the sparkplug/electrode area.

there is also a spark plug well gasket when u take the valve cover off it will be in the center were the plugs go into the head can't miss it check that

Do a leak down and make sure that it is the head gasket. It sure would suck if you changed it and got it all back together to only have the same problem.

Head gasket has nothin to do with oil really. Mostly coolant. Do a leak down and a compression test you might have bad rings causing blow by which = full rebuild
