Netters,
After two short ground runs yesterday to check for oil leaks I fired
up and made the first flight after overhaul. After an hour at
altitude over the airport I landed , only to find oil all over the
belly with oil dripping off the tailwheel spring. A major leak? I
guess so. I had lost 4 of the 6 quarts I started the flight
with. What a mess. I suspected the quick drain after having trouble
with it in the past. I cleaned up the mess and tie-wrapped several
small patches of cloth over the quick drain and went for a 10 minute
flight after supper this evening. No luck. Still leaks. With much
less oil to troubleshoot I now suspect a loose nut on the right rear
pushrod flange. I had to remove it after forgetting to install the
bottom cooling tin and must not have gotten it tight enough. I was
able to turn it 1/2 to 3/4 turn tighter. I can't believe that would
have leaked that much oil but I'll keep tracking it down with
successive flights. The front main seal, case halves, and accessory
case all seem to be just fine. When I get the leak fixed I'll be off
and running.
My oil temp and pressure were both dead on, even after losing 4
quarts of oil. Amazing. No other concerns.
I'll keep you posted.
Larry Flesner
