Angry Oil on 1 sparkplug electrode

Changed my plugs at 64,000 miles and the second plug from firewall on drivers side was not burning clean. Had oil on it, will take plug to dealer. Warranty runs out at 70,000. Any thoughts.

Re: Oil on 1 sparkplug electrode

Could be stuck ring, or valve seal for that cylinder. Compression test would test rings I believe

Dealer wasn't concerned, thought plug just wasn't burning properly. Said drive it a 1000 miles and pull plug again
