A little bit of seepage

Posted by Terry Grimwood at September 02. 2017

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?
