The write-up you did addressed/solved the problem. I took the 'Sunday
Afternoon easy way out' . I removed the mechanical fuel pump and routed the
fuel line directly to the electric pump. I then tore into the fuel pump. I
removed the rod the drives the rubber diaphram. I cut a hole through the
diaphram, leaving only enough rubber to act as a gasket. I then drove out
the pivot pin that retains the lever that extends into the block, removed
the lever, then replaced the pin. I re-assembled the fuel pump and replaced
it on the block. I took two lengths of fuel line and slid them over the
nipples, routing them up. When the engine runs, I can feel air pulsing
through the lines. There doesn't seem to be any oil in the air, so I guess
the fuel pump is convoluted enough to trap it. I intend to round up some
fittings to somehow finish off the ends of the vent hoses. I think I have
another pump in my box of parts, so perhaps I'll be able to build a nicer
appearing 'crankcase ventilation system'
Not a very pretty answer, but a 'make do' one that worked
This did cure the oil leak.
