Swampy442 Posted October 25, 2010 Share Posted October 25, 2010 Probably just overspill from a messy oil top up or a leaky cam cover gasket. Unless you mean the tip of the plug in which case thats something different! Quote Link to comment Share on other sites More sharing options...

Jellybean Posted October 25, 2010 Author Share Posted October 25, 2010 Just I got a miss fire last week and taught shit when is the last time I changed the plugs, so changed the plugs and she feels alot better but still not hitting 12bar,cant see any boost leaks ,will see again tomorrow how she goes its raining and traction is an issue, but the first plug nib in the cylinder closest the front was fully of oil ,the rest looked as expected Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 25, 2010 Author Share Posted October 25, 2010 The rubber pipes between the cams,middle one was c little split ,g presume this caused the oil on the outside of the plugs and coil packs rathers than cam seals, also are new rubber hoses flexible ,i had to heat the one nearest the wipers to get it on, is it possible to put these back on without splitting them Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 26, 2010 Author Share Posted October 26, 2010 Was on Supra Forums looks like it is Valve Stem Seals for the Oil on the electrode of the Spark Plug,But it doesnt appear bad/ she isnt smoking For the Top of the plugs coil packs its the valve cover gasket's http://www.supraforums.com/forum/showthread.php?t=448157&highlight=spark+plug http://www.supraforums.com/forum/showthread.php?t=282692&highlight=spark+plug Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 26, 2010 Share Posted October 26, 2010 Id replace the breather tubes, they aint expensive. As for the plug take it you didnt get any pics? If there was enough oil on it to make it wet in the cylinder Id expect major smokage. Maybe you caught some from the spark plug well while taking it out?

Thats true I could of caught some from the oil well, it was only on one plug, but definetly theres no smoke on start up plus when I start her up she is in an underground carpark so I would notice but I will take a closer look I will order the breather tubes today Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 26, 2010 Share Posted October 26, 2010 If there is definitely oil on the part of the spark plug that is inside the cylinder and there was not a lot of oil sitting in the plug tube and ran down the plug when removed? Then IMO there is a problem with the cylinder seal IE ring /bore wear/damage. valve stem seals rarely result in oil on the plug + there is usually smoke.
