D8800 in diesel 50 water in oil pan

have you checked the seals under the nuts that hold the tappet covers on? i had a d6 that was gettng water into the engine oil and it was pooling on top of the tappet cove because the nuts had been overtightend and created a well in the tappet cover for water to pool in. then it would find it's way into the engine oil. another posibility is that it could be going in the exhaust and then running down past the rings into the sump.

i was always taught to make sure the exhaust stack is covered, whether im shutting it down for 5 minutes or five days, make the muscle memory habit of covering the exhaust.

Second the dished valve cover water pooling problem. Not sure that the original bushing/nut system had seals. The good news is that the parts from later machines will fit and do have orings

Has the engine in your Diesel 50 been swapped out from the standard D 7700 to the D 8800 which was used in the RD 7 and later 9G 7's? D 7700 is a 5 1/4 bore and the D 8800 is the 5 3/4 bore engine.

A couple of ideas.

Every spring( or if the machine has sat for a while) before I start my stuff I just loosen the oilpan drain plug enough so that the condensation/water will drip out but not the oil. Takes a few hours sometimes.

I also had a gas 60 that sat outside( with a covered exhaust pipe ) and it always had water in the oilpan. I thought for sure I had a cracked block or head. Finally figured out that the water ran down the outside of the exhaust pipe and into the engine through where the pipe was (poorly) threaded into the manifold. There is a lot of surface area in a three? inch pipe-three or four feet long and all that water ran into the engine. I sealed up the exhaust pipe where it went in the manifold and no more problems.

good Luck,
