Water in oil oil in water

GMC · Feb 16, 2018

I have purchase a 1020 John Deere and the previous owner said "Tractor runs but water in oil pan and oil in radiator. Is this a sleeve issue?
He purchased it new. Thoughts? Thanks.

Certainly could be.

If diesel sounds like an oil cooler to me, do you have two hoses running to a housing under the oil filter?

Hopefully they did not run it too long if getting antifreeze in the oil as it eats up bearings.
Those are a wet sleeve engine and very common to have the sleeves get holes from electrolysis. I'd do some testing before tearing into it. Not sure about the oil in water unless the head gasket has failed ? You can pull the oil pan and pressure up the radiator and watch where it leaks from.

1020 didn't have engine oil cooler.
Most likely cylinders.

Speaking of running to long I bought an a and the tractor was running on 1 cyl from a guy that told me that the tractor always ran that way for all years getting wood out. I got a good deal and took it home to fix the dead cyl. After I remove the plug on the clutch side and put in a new plug it still would not run on that side?. After looking at it found the piston was at the top of head so started checking more out found water in the oil and oil in the water?. So me and the boy tore it apart and found that they ran this tractor with the piston broke by the wrist pin and the wrist pin wore a hole in the side of the block. ???? On your tractor its a good chance the head is cracked were the oil in the head has psi. The oil psi is higher then the water and that will push oil in to the water then when the tractor is shut off and no oil psi the the coolent is higher and then water is push in the oil. Hope that maybe just in the head gasket iv seen that happen also.

If it was the cylinders it should push water out the exhaust.

The early ones only have one seal per sleeve. Not unusual to leak. New sleeves provide and update and make it three seals per sleeve.

Cylinders can let compression in the cooling system without letting water in the crankcase. Most of the time it will push the seal out of the water pump. I had a 3020 that started doing that one spring so we cut the bottom off the radiator cap so it would not build pressure and ran it until winter when we had time to overhaul it. Just had to add water once in a while.It never got water in the oil. I know of a few others that have done it as well. Tom

I rebuilt an 1020 last summer for a guy and I found the sleeve seals to be bad and also looked like some one had installed them using silicone gasket maker. It had water in the oil. Crank also turned out needing to be turned due to it running that way for who know how long

No, the holes would come in the lower part of the
cylinders at the bottom of the water jacket.
Sometimes they would get oil in the water. I guess
as water circulated by the hole it would siphon oil in.
Anyway replacing the cylinders would solve both problems.

Ok is see how that would do it.
