I had started noticing a hesitation in performance. So, I changed spark plugs. Spark plug number 3 had oil on the gap end of the spark plug and I am sure this is what was causing the hesitation problem. I would like to know how oil could get onto the gap end of the spark plug and only one plug. Any help would be greatly appreciated. Thanks!

Thru the rings/worned cylinder/valve guides/seals

Do this drive the car around the block then park it and check it again if oil is not there-valves not there rings
