Hi Jim

    Are you certain that it is the front leaking oil?  Reason I ask - is
when I had a bad oil leak at the rear seal, airflow under the cowl pushed a
lot of the oil out the prop end around the spinner.  So initially I thought
I had a leak in the front seal.  It turned out not to be the case.  The oil
was actually leaking around the rear seal and I found out that because the
oil sump was accumulating 2 cycle oil that the level of the oil in the sump
had risen above my PSRU oil return fitting.  Once I lowered my oil in my
sump then the leak stopped.  I know this sounds too simple but that turned
out to be the case for me.

When I had the leak I lost approx 1 quart in 30 minutes of flight.  I think
I know a person who did have a leak from the front oil seal, he is not on
the list, but I'll see if I can get ahold of him.
