Antifreeze out of the exhaust

[ffdfireman18]

I finally got my 45 A running pretty good. I plowed 2 acres with it and took the disc to it. The problem I"m having is it sat for probably two months now. I shut the gas off and ran it out when I parked it. I went to start it yesterday and it spit out what looks to be water out of the exhaust. Quite a bit all over the hood and dripping on the floor. After further inspection it had some antifreeze in it. I checked the coolant level and it wasn"t really low. About 1-2 inches down from the very top of the filler neck. Anything to worry about? Bad head or head gasket? Any help or comments are appreciated.

Cracked head or head gasket

Might try retorque the head.,if its fresh overhaul. Sounds like seepege thru the gasket. Check oil for antifreeze there.

The manifold studs go into water too.

My first JD tractor was JD "G". It would leak anti-freeze into the cylinders if it set more than a few weeks. I had the engine completely apart and check out. Nothing could be found wrong. I owned the tractor for thirty years it did it until I sold it and the new owner says it still does it.

My solution was if I was going to be using it in a month or so I just opened the pet cocks when I went to start it. It would blow the water out the pet cocks. For over the winter I just removed the spark plugs and filled the cylinders with diesel fuel. That would keep it from rusting the cylinder walls. I then just spun it over a few time and re-installed the spark plugs.

Did these still have the tubes for the push rods in 45? I had to replace the steel ones with the brass replacments in both my 39 A and my 37 BO. Also, I've seen hairline cracks in the heads where the coolant flows around the intake valve chamber. The last series of A's no longer had the tubes.

I'd retorque the head then premix some bars leak and dump it in and then go plow again. This stopped my B from weeping thru the gasket.
