Allis 7045

Ive got an Allis 7045 with some coolant coming out of breather and also accumulated on cap of oil fill. Very small amount and not showing on the oil dipstick. Had it overhauled about five years ago. Any ideas would be great!

Coolant dripping from the rubber breather hose?? That is very bad. After sitting overnite, remove the oil pan drain plug to the very last thread and you'll see the coolant dripping. Could be sleeve O-rings......could be a head gasket.......could be the engine oil cooler. Depending on how bad it is, I guess I'd start by making sure the radiator is full and pressurize it with a 12 psi (and no more) hand pump. Then, remove both engine oil filters and leave them off. If there's no coolant dripping there, remove the engine oil pan and see where it's coming from. Might have to plug in the block heater overnite to make it leak. Remove steering tie rod for pan to fall down out of there. Plan ahead and have it sitting where you can tear the engine down if needed.

Thank you DrAllis for the response. I unscrewed the drain plug to the last thread and only oil came out. Hopefully this means I've caught it early. I saw a drop on the breather tube a few days ago before I ran the tractor and then again the next day. I had been working ground but now at home and just letting it sit. Is the engine oil cooler in the filter housing where the block heater plugs in? I noticed a small pinhole there with some antifreeze coming out of it also as I have it sitting at home.
Thanks
