i was just looking over the engine untill i noticed some oil comming from the left hand side spark plug, after chaging them all i noticed that all of the THREADS of the spark plugs had oil on them, someone said its the steam valve seals? is that true? as the engine was rebuild in feb this year. just need comfirmation thats all. the 1st spark plug (left hand side) was the worse.
all help much appreciated
thank you
