Oil on spark plugs
6 Attachment(s)
Pulled a few of my plugs to check condition and discovered that they're covered in oil. The oil appears mainly above the threads (i.e. outside combustion chamber) so I'm thinking maybe a valve cover gasket. Looks like evidence of some oil leaking at the gasket on the outside of the block. Have a look at the attached picture and let me know if you agree or if there's something else this may be. I'll try a compression test too.Attachment 116245Attachment 116246Attachment 116247Attachment 116248Attachment 116249Attachment 116250

Looks like the valve cover gasket to me, at least in part. The stains on the cover and heat shields are telltale.

I would suggest you also check the spark plug leads for damage. Oil like that is really bad for the boots.

Thanks, I'll check out the boots. Looks like the spark plug tip is just showing regular wear.
