Oliver 1750 Oil in Water

I have an Oliver 1750 gas tractor that im getting oil in the radiator but no water in the engine oil. Anybody have an idea whats going on?
 
we had a case like this --the steel power steering lines cross the radiator overftow lines and had rubbed together ---changed water several times--before finding it---there is not anything connected to the water system --hope this helps
 
If your oil cooler lines go into the bottom of the radiator they can develope a pin hole inside the radiator and cause your water to have oil in it.
 
We had a couple of 1800 engines do that. It was a combination of 2 things. The oil under pressure fro the ain bearings would go past the sleeve sealing O-rings. So to fix he problem the mains needed to be replaced along with the sealing rings on the sleeves. Questions? J.
 
That was my problem also, oil cooler line in the radiator developed a leak. I solved it by going to an Off-Road shop & getting an external oil cooler which I mounted in front of the radiator, works great now.
