For those of you that remember my original post:-
Disaster!!!
#1831123 - 20/04/2008 21:04 (sorry, don't know how to link)
The yard has just called me to say that they've had the engine out and refilled the sump followed by a test run- no evidence of an oil leak from anywhere??
They are going to give it an extended run during the course of the afternoon and if that doesn't produce a result then this incident is surely a mystery.
Being a pessimist at heart, I imagine that the cause will become clearer as the season wears on

I have a Bukh 23 on Kate. That has recently done the same thing. I've cleaned the oil out of the bilge, pumping it into a bottle via a small hand held pump. I refilled the engine and though it does lose a bit still I can't find where it came from.
I do have a LARGE spare can of oil on board now!

You tell me alcohol isn't the answer, but what was the question?

Thanks, I'd tried the URL route but not in the way you describe

That's interesting.
See the previous post- if you've eliminated the main contenders then we are both faced with a mystery.
Main contenders reminder:- loose/corroded oil filter- badly seated oil filter- oil supply pipe from oil pump banjo union to rocker box known to corrode and leak- loose sump drain plug- drain plug modification, to give easy access for oil change, incorrectly done resulting in split/perished hose and thus leaking.

I don't know that motor, but is there an engine breather somewhere? If there is, is it clear?
If an engine breather becomes blocked the normal blow-by can pressurise the engine, and then seals / gaskets that under normal conditions do not leak, could start leaking.
Try carefully undoing the oil filler cap (or dipstick) while it's running, if there is some pressure there when you release it, then check for a blocked breather.

Sounds like the same thing happened to us on our Yanmar. You say the old oil seal was still on the face of the engine block when you removed the oil filter, so when you had replaced the filter with a new one last spring there were then two seals back to back. At least it lasted a year - ours lasted just two weeks. Luckely we had the engine on idle when the alarm came on and all the oil had been dumped into the bilges. I can't understand how this has happenend as the oil seal is recessed into the filter with a flat face to go against the engine block.

Since the oil filter base is out of sight when the alternator/starter/flywheel are in situ I can't say if the separated filter seal I removed came off the filter I've just replaced or not as I didn't think to check it- at that time all the other gear was in place and I just unscrewed it by feel and dumped it in the container containing all the recovered oil from the bilge.
If it was from a previous filter then it could well be what you say and obviously something I must take care to avoid again.
