Oil on spark plugs

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.ImageUploadedByTapatalk 21367770058.034685.jpgImageUploadedByTapatalk 21367770079.575597.jpgImageUploadedByTapatalk 21367770115.736107.jpgImageUploadedByTapatalk 21367770148.309655.jpgImageUploadedByTapatalk 21367770166.995205.jpgImageUploadedByTapatalk 21367770183.675500.jpg

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.
