Wisconsin VH4D engine

[Bigg_Billy]

Hello All,

I have one of the original 25 1965 Owatonna Mustang Series 1000 tractors with a Wisconsin engine. The tractor is seldom used but is always stored under cover. Every year when I change the oil it is always milky. I'm assuming it is from condensation inside the engine. Just wondering if others have had the problem and if anyone has a cure.

Thank you,
Bill

Use it more often.

It isn't getting hot enough to book the water out of the oil/crankcase.

Having it covered may be adding to the problem... But I don't know what the right solution is. Cover it less tightly? Make sure there's a vent in the top of the cover? (Imagine a boat cover with a vented pole)

storing under things like tarps are not ideal. If you can can you put it under a real roof and then see if the problem still exists. I assume it is only the engine oil and not the hydro. oil. and yes it might be that it is not getting run long enough to cook off any condensation.

Thank you for the replies. It is just under a lean to shed roof so its well vented...but... I use it mostly in the Winter to plow snow in my driveway and it sits all Summer. I'll try running it in the Summer to heat it up.

Just saw this thread and I have the same issue with my New Holland/Sperry L325 with the VH4D engine. No issues with the hydo oil, just engine oil.

Mine does not get used often only a couple times a year. We try to run it at least once a month but that does not always happen. Sometimes it is several months between start-ups. It is kept out side. We noticed this issue several years back and at that time we did not keep it covered. My father and I thought that water was getting in the motor somehow even though the exhaust has a weather cap on it and there are no leaks from any gaskets that we know of. I then started covering it and the issue continued.

A person that my father talked to stated that this is a common problem. He says he still runs his with the milky oil. I don't know if I trust that logic. We try to change the oil at lease once a year, sometimes more often than that.

I understand that running it more often will probably keep it from getting milky, but will the water boil off if it is run long enough or should I just keep changing the oil more often if this should keep happening?

Did running it in the summer help with this issue?

Thanks.
