Ash fouling on plug?

Postby dmchan » Thu May 25, 2017 7:24 am

I changed plugs this weekend and found #6 had some ash fouling. I noticed some oil leaking from the valve cover gasket on the driver side. Is it likely this is the cause or am I looking at a deeper problem?
Hoping someone here has experienced this before.

Thanks!
