need help with a 3594 and 1070

I need some information on a couple of case tractors. I have a 3594 with a trace of antifreeze in the oil. We have been sampling the oil regularly and it has just shown up in the last 2 samples. It has 12,000 hours on it. Was overhauled when I bought it at 5,000 due to too much either on a cold morning. What do you guys suggest I look at first? This tractor gets used almost every day in the winter for running a bale processor and for making hay in the summer.

Secondly, I have a 1971? 1070 with over 10,000 hours on it that has never been touched. I pulled the engine oil plug to do the normal winter service on it and about a pint of antifreeze came out. What do you suggest here? This tractor runs a hay rake and a 10 inch auger so not alot of hours.

Any advice would be greatly appreciated. I have lots of case tractors but have never had to over haul a motor on one of them. I am hoping it is something as simple as an oil cooler, etc. Thanks!

Bryan, a oil cooler leak usually shows up as engine oil getting into the cooling system. A small amount of leakage can leak by a head gasket or cracked sleeve flange also. But considering the age of both units the most common leakage area is the orings on the sleeve. I have never seen a easy pore in fix for this problem work, so the only sure cure if this is the problem is replacing those orings if that is the problem. You can drop the pan and leave unit sit for a few days while watching for the source of the leak.
 
Throw a can off stop leak in them, get the engines warm and see what happens. I did this on a 830 case that gets used almost every day. Worked for me.
 
May as well as replace all orings if we are doing one? Do you have a cost for parts for that? Also, is there a good place to order the parts from? Thanks for the input!
