Oh.

Probably ought to. :-)

Nobody has mentioned the thing I would check first- blown oil cooler.

Hey,
Some seawater is in my newly re-built MDIIB diesel (volvo),
what do I do?
I changed the oil five times and the filter twice. Runs great
otherwise.

Remove the water pump and check the O-ring shaft seals. Also if
you engine was repainted, make sure the weep holes on the shaft
housing are clear. We had the same problem on the MD-11 we used
to have. They had filled the weep holes with paint and when the
seal blew out, the water could not go out the weep holes so it
was pumped right by the rear seal and into the bottom end of the
engine. I was told by a Danish cruiser that this was a common
problem. When it happened again in two years, for another reason,
we replaced it with a 3GM-30F Yanmar. More power and less weight
and I don't worry about the engine filling up with seawater. The
cost of parts for that old engine, if you can find them, must be
made of gold and platinum. I still have cylinders, heads, MS-7
gearbox, starter, alternator, and a few misc other parts if
anyone wants to come to South Carolina and haul them off.

Another source of possible sea water intrusion is through the seawater
injection into the exhaust. Many engines are below the waterline and
require a vented loop ABOVE the waterline to prevent water entering the
engine through the exhaust. Since your engine is newly rebuilt, the
plumbing might have been moved when it was reinstalled.

I have a friend who has this problem, and it turns out it may not be all that
serious. He changed oil and ran it a bit, then changed oil again and ran it,
and did that a couple of times. When he had finished, the mechanic told him
that he had just steam cleaned his engine.

But there may be more to it that I have forgotten. I am going to sent this to
the guy and see if he won't tell any part of the story that I forgot.

What I do know, however, is that with a little work he certainly didn't have to
have the engine rebuilt.
