Diagnosis of misfiring M5 E60

Further to the misfire on Cylinder 3, it looks like the problem has been narrowed down to oil leaking into cylinder 3 (after new spark plugs, etc didn't fix problem). Interestingly, the engine error message (and reduced power) only occurs on cylinder 3, under higher revs/stress in moving from gears 2-3. Not any other gears. Sounds like head may need to come off - will keep you posted.
