I have oil in my plugs, so while I am changing the internal gasket is there anything to replace while it is all in bits? It's just hit 190k on the way home from work this morning So some new parts can't hurt can it? Plus I know of a misfire as I can feel it, it's only on idle though doesn't affect the drive? :/ I'm no mechanic so I don't really know how to explain it ha ha.
