Hi,

I've just changed my spark plug myself just now and realize there is engine oil in my spark plug chamber, may I know what you did besides changing your cover at the time you encounter this problem? I'm asking because I'm afraid that foreman is going to cut my throat by doing unnecessary stuff when I visit them tmrw.

Besides, I've also encountered serious oil loss without oil leaking out of the engine, may I know is oil loss and oil leak into spark plug chamber related? If it's not, have you encounter such problem?
