Just purchased a 51 8n. When I went to purchase it, it was running smooth but smoking much. He told me it has smoked for years but always ran fine. I just need it for some work around the house so I picked her up.. Has a loader and backhoe. They operate fine. How could I have so much oil in the radiator?? Is she dead?? Thanks!! Tom..[/img]

I'd drain it flush it out real well then fill it up with good coolant. I'd also check the compression on all the cylinders. To have that much oil in the coolant one would almost have to have a major crack in the block some place. But it could also be one of those old things where years ago it you lived some place real cold they used a thin oil like kerosene as a coolant.
By the way what brand of loader and backhoe does it have?? I have a 1950 8N ford with a dearborn loader and a Scout backhoe on it

Probably not actuall oil but burn't oil byproduct pushed from high pressure of piston through bad head gasket into low pressure radiator. Common problem and easy fix, just remove hood so you can get to head, remove and clean up good and new head gasket. The worst problem is flushing the engine and radiator enough to get the gunk out. Depending on price of head gasket I am guessing a $10-15 repair. And a compression check will not show up the problem. That is common on all the Ford 9N 2N and 8N tractors from 39 to 52. An engine that is using oil will show up quicker in radiator than one that uses no oil as that is the same thing as comes out of the tail pipe on an oil burning engine of any car or tractor. So common just get a gasket, only one gasket needed and polish the head and block to shiney with fine wet or dry sandpaper. Just do a carbon removel on pistons as well as that carbon raises compression to make it push the exaust gasses out of the cylinder into the radiator easier.

Start with a head gasket.
But that much oil is concerning.
Normally I don't recommend flushing a cooling system with chemicals, but in this case some type of alkaline base detergent would help break that up. Something like Purple Power degreaser.
Once it is running, put about a quart in the radiator, top up with water, let it run up to temperature at fast idle, drain and repeat several times until it clears up. Then flush thoroughly, engine running, block and radiator drains open, hose running in the radiator.
Might want to replace the hoses while it's apart. The problem with oil in the cooling system is it deteriorates the hoses.
