To my knowledge (had several MD2 engines), there is not water passage that
would allow the water to get into the oil.

However, that stated; there are two possible causes that I can think of.

1. The water pump is mounted on the crank case and there could be leaking
pump seals. Actually that would mean that both seals are leaking and the
weep hole is plugged.

2. The is a very remote possibility that the water passage between the head
and the cylinder has a "leak-over" via a bad head gasket. This would mean
that the water is finding it's way to the oil drain back passage where the
push rods come up from the cam.

Frankly, I think #1 is your source of water or it is due to condensation
that is acculating in the crank case. (I have had this problem in my Entec
gen set due to the alum. crankcase and infrequent useage.)

If you need the manuals for this engine (owners or shop manual) I have them
on my web site at http://hood.hctc.com/~esteve/private/manuals/

Thank you for your reply. After I had the engine put together again,
the engine started perfectly, but not soon after water literally
"flooded" from the injection where the engine gets the fuel (don't
know the right english words for engine parts). After checking the oil
level there seemed to be a lot of water in the oil in a short span of
time (1-2 min). No leakage was found before the engine started. Maybe
that speaks for the water pump and leaking pump seals.
Thanks again!
