why leaking and how to fix it?apex seal gone?or injector or just not fixed yet?please help..

 

The spark plug must not be seated or the ceramic could be loose Just replace the plug. Or it could be a small crack in the housing casting. Replace the plug first and check it after awhile.

Clean the oil stain off with a can of brake parts cleaner or something.

 

thanks reply tripple 7's and i will clean it up then have a look

 

Does the staining originate from the leading (lower) plug? If it's coming from above the spark plugs, it is probably goo from the knock sensor cover.

 

I sure it is leaking from spark plugs so if it is goo from the knock sensor cover.any solution and any problems affect my car now?

 

pull the plug you should be able to tell for sure where it is coming from
