Got oil weeping down the crankcase from between the head and barrel, in the vicinity of where the foreward-most, outer-most cylinder head stud is located. I'm thinking blown gasket, but would be very happy for anyone to offer an alternative reason.
While on the subject of errant oil, after a run I always get a trickle running down from the oil tank filler cap, despite having fitted a thicker washer. The tank is definitely not overfilled and I can't imagine the pressure of the oil coming out of the return is enough to force it past the cap. Any ideas?
