Default The unpleasant case of the haunted yanmar

Thanks Larry. I've looked really hard for air leaks and fuel leaks...
The fuel tank is higher than the engine and I have bled the thing very
well. I'll look some more, but don't understand why it would get
better when it gets warm... Also, if the engine has been wamed up
sometimes it doesn't have the problem the next day... If it was the
injection pump would it ever run well?

As things heat up they get bigger, sealing the hole, probably. If your
fuel tank is higher, gravity pressure should make it so there's no vacuum
in the whole system...so there should be no bubbles, only diesel fuel
leaking into the hull. Hmm....might be more of injection pump problems.

Has anyone done a compression test on it? How many hours are on it??
