Hi Fred
Oil used to leak from the front (MAG) and rear (PTO) cap head screw journal bolts, it is a flex wing trike, and from the bottom right hand side of the cylinder on No2 and No3, as well as between cylinder and head.
When I tried to torque the cap head screws they were loose and wouldn't tighten as they screw into an adaptor and this just turned.
Mark.
