I am jumping in here without knowing which engine you are talking about, but assume it is the gas 440?
There has to be a crack somewhere if water is getting in the oil. Either the head gasket is not sealed, or there is a crack that you have not located somewhere.
Sorry I can not be of more help.

Just came across this post as I haven't been on the board for several months. My guess if you have water in the oil and water out the exhaust the crack between the valve guides would be a good possibility. Another place there could be a leak is around an injector if its a diesel. This I'm not sure about as I'm not familiar with the 2-53 injectors but I have seen it on larger Detroit diesels. Mark:

Any crack no matter how small will leak.

If the engine has piston sleeves, there is a seal (sometimes an O-ring) at the bottom of the sleeve, which can leak. Also with time, the water will eat small pin-holes in the base of the sleeve through electrolysis.

My suggestion is to remove the radiator cap and insert a rubber stopper with a tire valve and gauge so the water jacket can be pressurized with compressed air. It does not take much pressure. Look for a pressure drop in the gauge or maybe a hissing sound from the crankcase filler tube.

If the leak is slow, maybe some radiator leak sealer will work. Otherwise is it tear-down time.

It could also be a headgasket problem if the head/block surface was not clean or the head torqued down properly. Both oil holes and coolant pass through the head gasket. I found a good headgasket sealer is just standard spray paint. Soak the gasket both sides, slap on the engine wet and torque it down.
