Oh.
Oil can only get on the plugs from the piston rings, valve guides or head gasket.

Oil on plugs could make it run lumpy too!

Is it on all of the plugs or just one?

Might be an idea to compression test the engine.

not true dude!

if its the plug directly below the filler cap, you can spill oil on it when you pour it in!

good point on other causes though :cool:
