    C-85 oil leak

    A friend just did his first startup on a freshly overhauled C-85-12F. The through stud at the top front of the front main bearing is leaking like a sieve. Not a jet, but you can see the oil seeping down the outside of the crankcase when the engine is running.

    Any thoughts about likely causes and fixes?

    Sounds like a piece of dirt in the mating surface near that stud. Good thing these disassemble and assemble so easily, huh?
