We had a customer bring in a car, wasn't running all that well. Customer claimed a small amount of water was mixing in with the oil, according to a member of authority on this forum(who also helped assemble the engine), it was just condensation and not to worry about it. Well with repeated oil changes and still water pouring out he brought it to us. We did a compression test, came out a bit low so we decided to check the oil, milkshake. We go to drain the oil, and for the 1st 30 seconds of the drain plug being a few threads loose, water poured out. Then, "yoo-hoo" colored substance followed.
Long-story short, where one of the head studs screwed in, it was cracked from there to a coolant passage on the block deck.
I think all signs point to cracked blocked. Sucks to say, but its not that hard to pull it back out, just machining will be the most costly part.
