C85 Oil Leak
A small oil leak has shown up topside and immediately behind the nosebowl
on my Zodiac 601 HD powered with a C85. As near as can be seen, the crankcase nipple connection and hose leading to the air/oil separator is not "wet" or showing leakage. Neither the hose nor air/oil separator are blocked. There is extensive riveted baffling around the crank/prop flange area which blocks a direct visual inspection. Having heard about leaking crank front oil seals, is the replacement method a total engine case split or some kind of split ring seal similar to old chevy small blocks? any help would be appreciated, thanks, Dick |

C85 Oil Leak
----- blocks a direct visual inspection.
Having heard about leaking crank front oil seals, is the replacement method a total engine case split or some kind of split ring seal similar to old chevy small blocks? There is a split seal for Continentals with flanged crankshafts which installs without too much trouble. A few years back I replaced a seal on a C-85 without doing enough troubleshooting. After replacement, the leak remained. it turned out the crankcase vent line had been moved and was pressurizing the crankcase. Cheers: Paul N1431A KPLU |

C85 Oil Leak
Paul,
Thanks for the reply. I finally found a Continental Manual showing that split seal used on my flanged crank. But I have noticed lately that my air/oil separator is pushing almost nothing out the drain hose to atmosphere. ie: lot cleaner than usual belly G. Now I wonder about that crankcase being pressurized possibility.....The one item I didn't check for blockage was the 90 degree fitting coming out the case side. Sure would rather unblock something than pull that spinner, prop and baffling G. Dick "Tri-Pacer" wrote in message ... ----- blocks a direct visual inspection.
