Hello All,
For the last few years, I had a significant loss of oil whenever I
ran the engine for more than a few minutes. During 1 run through Hell's
Gate back to home waters in Raritan Bay, the oil light and buzzer
sounded (naturally at the worst time). We hoisted the sails and sailed
down the East River - not recommended! When in Raritan Bay the wind
died, I got a tow from SeaTow back to the mooring. This convinced me to
rebuild the engine over last winter, however, after a great deal of
trouble shooting and having multiple eyes look at the situation, we
noticed that the bulk of the oil was accumulating on the side of the
engine with the dip stick. The dip stick slid in easily. Further
exploration led to the conclusion that the source of the oil leak was,
in fact, the dip stick. Finding a new replacement for an old 3GM was a
task as all the dealers said none were available. An old salty engine
repair man I met at the Annapolis boat show told me he could get one. He
did. I now have a tight seal and no oil leak! If you have an old Yanmar
and it has a mystery leak, check your dipstick for proper fit.
