For some time now my x been leaking oil ,but i never knew where it was coming from and i still don't .From time to time i see drops of oil here and there.dont have a clue. while upgrading my ignition coils to high performance and changing my sparks plugs due to a ignition misfire I noitice in one of the sparks plugs chambers there was oil around the threads,Could this be a VALVE COVER GASKET PROBLEM? Other than that the X running fine no misfire for now.( Help is really needed )
