Dudes, Noticed when I was changing spark plugs (from the standard Denso's to 6 lovely NGK Iridium IX's - they make a noticeable difference I have to add) that some of the old ones had a moderate layer of dark (does that mean old?) oil coating the threads. The tips of the plugs were clean, dry and grey however. I also noticed that a thin layer of what seems like 'fresh' oil lined the lower edges of the spark plug remover (where it brushes against the side) after I'd extracted it.

I expect this means that the rocker cover gaskets may need replacing? Am I on the right track with this one?
