i have a 1944 john deere A that i am restoring . the crank case vent cap had blown off while it was being hauled here from south dakota and it rained a couple of times before i got over to the trucking company to pick the tractor up . some rain got into the crank case and turned the oil milky . i changed the oil and the tractor runs great but i would still like to clean out the engine a little better . years ago , my grandpa had a 1010 JD diesel crawler and the JD dealer told him every few oil changes to drain the oil out and refill it with diesel and turn the engine over_______without cranking it _________ and this would clean the engine . then drain the diesel and refill with new oil . i was curious if this would work on a gas burner without damaging anything ??:shrug:

It will work just fine, but the way the A,B,G, and H tractors were desgined all the water should have drained out when you changed the oil providing you let it sit open for a while. You can do it if you like, but I think you are going to just waste your money on fuel for a problem you don't really need to worry about.

that is how I have done it. fill it with diesel fuel then pull the spark plugs and turn the engine over by hand. you should be able to turn it over fast enough to build oil pressure and get it flushed pretty good. then I would drain it overnite. put a couple quarts of oil back in it, turn it over by hand to get it pumped back through the system. drain that out and change the filter and put fresh oil in it and you should be good to go. if your worried about the diesel not haveing enough lubrication you could mix it 50-50 with oil I guess.

The best washout for the engine oil is engine oil.
Put it in and warm the engine, then drain. If the oil is clear in the drain pan the engine is clean.

They used to add 2 qts of kerosene to an engine before an oil change and idle it for 15 min but that is hard on cams. You could get an overhaul for about the same as a house payment.

If the oil was milky, the inside depends on the anti rust propertys of the oil that was in it. If it was non detergent it probably has rust, but most people use the same in everything so there probably is no damage.

If there are pockets that water settled in a modern oil will emulsify with it and change color ( probably grey ) and if it comes out black there is soot in the engine. Change the oil more often and the detergent will clean the soot out.

maybe put some motor flush in it get it real hot and drain it when hot

your worrying about a problem that you dont have. run the engine at hi idle until it gets up to full temps,,,any water in the oil will evaporate and be gone.

i just wanted to say that I have a 44 model A jd too. In the original owners manual it recomended to drain the oil out and refill with kerosene then start it up run it a few minutes then drain it back out. This was in like the winter storage section of the manual. I thought to my self no way would I do this. but thats what JD recomended. just thought it was funny

that's basically what the JD dealer told my grandpa about his 1964 JD 2010 crawler except it was diesel and he just turned it over a few times without cranking it . by the way , i first said it was a 1010 but it was actually a 2010 .
