1950 Super A Thermosiphon cooling I am getting about 1 to 2 ounces for water out of the oil pan drain plug for about every hour or 2 of running. Ideas of where it is comming from and how to correct the problem? Already retorqued the head to 70lbs.

The super A uses a wet sleeve engine which means coolant contacts the sleeve. There are sealing rings at the bottom of the sleeve to seal it to the block. If these seals are bad coolant will mix with the oil. I would do what another post suggests pull the oil pan and pressurise the cooling system and look for leaks.

You might want to try and pull down the oil pan and pressurize the rad with a pressure tester and look up at the cyl's or block and see where the antifreze is running from. That might help you get an Idea where its coming from. good luck

I think your block maybe cracked internal. You should llok into that.

Michael: If you remove the rad cap when engine is reasonably warm and with tractor running, do you get any bubbles in the rad? Your description sounds a bit like my Super A several years back. You retorqued the head, but it hasn't stopped. I wouldn't rule out either of Dave's suggestions of head gasket or crack. I tend to favour the idea it is head gasket. I think most cracks would allow more water in the oil than you are getting. My tractor was the head gasket, that cured it.

Of course the head gasket also depends on which way it leaks. It could leak from water jacket to top of piston or to valve push rods and oil pan, or both. Leaking from water jacket to top of piston will cause a lot of bubbles in rad, whereas a leak from water jacket to crank case will depend on a number of items if creating bubbles. Blow by within the engine, crank case breather, etc. Best call would be remove the head, and see what you find.

I had this on my Super C with a new head gasket. I ran the torque on up to 85 lbs and it has been fine ever since. I was useing an old hand me down torque wrench and it may not have been very accurate. Hey what the heck if it does not help then you know to look further into it.

There is a frost plug on the back of the motor, I'm not sure if that would get into the oil pan or not. Regardless, it'll need some repair. If it aint' that, than you have a bad head gasket, crack in the block , or head some where.
