razziel24 Posted 7 hours ago Report Share Posted 7 hours ago Hello there. Did anyone diagnosed and corrected this issue ? Im having the same problem on my 2019 ST No oil marks in the garage floor, no blue smoke, no visible oil leaks in the engine... Just one weird finding... the sparkplugs for the visible bank (the ones i could check) have oil in the outside, i removed them and the inside is fine, no oil inside the chamber. Could this be a valve cover gasket issue ? pcv ? any help would be gladly appreciated. thanks Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted 59 minutes ago Report Share Posted 59 minutes ago I would offer two possibilities. As you suspected, one very real possibility could be that the plastic valve cover is cracked, or the sealant has failed, creating an oil leak that drips into the spark plug wells. Another, (and more common possibility) is that oil was spilled during a past oil change and pooled in the spark plug well. Quote Link to comment Share on other sites More sharing options...
