After wrestling with my front crank seal, it still leaks. So, when I bought another seal to install the guys at Fresno airparts gave me a copy of a Continental service bulletin that addresses installation of the seal and subsequent leaks. After removing the seal, the SB tells you to take out the upper spark plugs and rotate the engine with the starter with the prop off while using light emery cloth to remove any surface imperfections. Then , it tells you to use 180 grit emery cloth and make a Helix pattern at a 30 degree angle in the direction of prop rotation. This has to be done by hand, a little at a time as you rotate the crank shaft around. Once complete, there is a Helix or "rifled" pattern around the crank behind the seal. Continental says this is supposed to pull the excess oil back away from the seal while the engine rotates. Lastly, I didnt push the new seal in quite as far as the previous one, to keep the seal from riding on the same spot on the crankshaft. I'll know tomorrow, once the sealant dries and the rain quits. I'm tired of getting oil on my windshield. Other than that, all is well. I got a 4- pack of Nuvite polish for Christmas and I am holding off on the polishing until I get this oil leak fixed.
