As it was a second hand engine, it seems highly likely that the cylinder head gasket has failed, or worse, I’m not familiar with that engine but if it has wet cylinder liners then the water seal on the liners could have gone. Which all points to the engine having been “ cooked” at some time in the past, I agree that the lack of a siphon shouldn’t compromise the oil unless it was very serious and water had got back into the cylinder head and an attempt to turn the engine over had been made.this is unlikely to be the case as you would have ended up with a cracked block!
