oil in the spark plug?

Lorenzo · Sep 16, 2011

dear All,
I found traces of oil on the thread of the left spark plug. Moreover, after a long ride, I found it a bit crusted and the oil level lower of 1/2 lt.
What do you think? Any idea?

You need to check valve guides for wear/possible looseness in head and intake seals . Any way you look at it you will be pulling the head ,inspecting for head gasket leakage internally on that side as well . When was the last time you put the head into a shop ?

I have just rebuilt my head and it has traces of oil up the pugs but runs fine and burns very little oil. Unless you have symptoms I would leave alone. They are bound to wear.

Lorenzo, could you post a photo of your plugs? If you went through that much oil on one ride you must have been laying down quite a smokescreen?

Sounds like the plug wasn't screwed in tightly enough, or the washer was in poor condition. That wouldn't explain the 1/2 litre of oil though,
