[C320-list] Oil Leak

[Jeffrey Hare]

Alan's right.  My boat #809 leaked from this spot also.  The "fan" belt goes
directly over this little cover.  I think it only has  or 3 screws on it
however.

The manual says it's for hand-cranking the engine, but with the belt
crossing directly over it, it wouldn't be possible.

Anyway, Remove this cover and if there's a little oil in there, it's likely
to be your culprit. The paper gasket wouldn't seal on my boat. I cleaned up
the surface and bought some oil/gas resistant liquid gasket material (looks
like thick black silicone goo) and put a bead around the gasket seat and put
the cover back on very loosely.  Then after it set up for a day, I snugged
it down lightly and it hasn't leaked since.

I talked with the yanmar guy at the show and he confirmed that the cover is
made of thin metal.  It was a little too flexible to didn't seal well with
gaskets.

Ken - I had this problem on #808 for quite awhile.  On the front of the
engine, there is a plate with, I believe, 3 screws and what looks like a
small Dixie cup sticking out.  Someone told me that this was originally for
a hand crank but I am unsure if that is true.  At any rate, oil dripped out
of this area about 1 drop a day - it took forever to figure out where the
leak was coming from.  Sorry I can't describe the area better but if you
don't have this resolved by next weekend, I can take a pix of the area I am
talking about and send that to you - let me know.

Hi all:

I was away for a couple of weeks and was surprised to find engine oil (two
ounces or so) sitting in the pan beneath the Yanmar engine when I got back. 
It didn't come from the filter and it isn't transmission fluid. It is
clearly engine oil. The engine has only 165 hours on it. Since the bottom of

the engine sits at an angle, it is hard to tell where it is coming from.

Has anyone else experiences an oil leak?
