Ford 4400 diesel Blowing oil/antifreeze

I have a 1970 Ford 4400 3 cylinder diesel that appears to be blowing an anti-freeze/oil mixture out of the exhaust.

Last summer, I noticed the tractor was overheating and had to add antifreeze. This Spring, I noticed the tractor was low on antifreeze and topped it off.

While working, The tractor suddenly started to smoke excessively, particularly at low idle. The smoke appeared to be more of a white color and smelled like anti-freeze. I then looked at the engine, and noticed a watery oil mixture coming out of the exhaust.

I checked the oil level and noticed it was close to normal (somewhere between the add and full line). The antifreeze level was so low I couldn't see any anti-freeze in the radiator.

I am guessing the anti-freeze is possibly leaking into the engine and burning out the exhaust through a bad head gasket.

Does this sound like the possible problem? Are there any other things I can check before disassembling the engine to determine what the problem may be? I wasn't sure there was an easy way to diagnose a cracked head or block without disassembly.

Any help or suggestions are greatly appreciated!

Thanks,

Steve

If you pull the injectors, I'm betting that one or maybe two of them will look "steam cleaned" compared to the other(s), which will tell you which cylinder(s) the coolant is getting into, but it won't tell you whether it's from a blown head gasket or a cracked head, or possibly a pinhole in the cylinder wall. For that you're going to have to pull the head off.
