BodybyFisher Posted February 14, 2011 Report Share Posted February 14, 2011 No big deal, oil in the spark plug ports is very common The cam covers have spark plug hole seals, when the cam cover seals are done, the spark plug seals are part of the job. It is quite difficult to replace the cam cover seals as its difficult to get the cam covers off (water pump pulley and no room for the rear cam cover) The oil did not cause your misfire, oil wont conduct electricity, its actually an insulator Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
JimD Posted February 14, 2011 Report Share Posted February 14, 2011 A trace of oil in the spark plug hole is not uncommon; the O ring seals in the cam covers can seep a little over time. Did you check the other three plug holes while you had the ignition coil package removed?? Jim Drive your car. Use your cell phone. CHOOSE ONE !

drcmrn Posted February 14, 2011 Author Report Share Posted February 14, 2011 Jim, what does GTMA stand for? did find oil by the other plugs, not as much as cylinder 6 Dan Link to comment Share on other sites More sharing options...
jndnaps Posted February 14, 2011 Report Share Posted February 14, 2011 I had the same thing.. It was mainly in one cylinder. When I changed the plugs I soaked it up with a paper towel before I removed the plug. I check back once a week or so and so far not much of anything. Guess mine is just a very slow seeper.
