Hi I've been running at a steady 17.5 amp load for four hours. The water temp is just under the bioiling point. I get a whisp of steam occasionaly. The oil(crankcase door) is at 170 with my infared thermo. The outside air temp is around 95.
I may have to insulate the pipes for winter operation.
The coil under the crank seems to be doing what I want, so far.

The oil temps are up 4-5deg after 1.5-2 hrs run. I may have to make some mods to heat the oil further. I won't know untill I have an 8-10 hr run.
The discharge from the tubing array goes to the manifold on the engine. The hoses from the heads go to the sides of the freon tank. the water level in the tank is near the top. the upper 1 1/2" tube will go to a radiater to condense the steam. If all this works the way I want I will add a sight glass to a heavier tank for permanent use. These disposable tanks are vrey thin.
I tried a straight tube without the tank and the result was steam and water being pushed out the top. I tried it with out the pump and there was a lot of steam and not too much water circulation. This lack of circulation was a concern to me.
The pump is a weak point for me. If the pump stops?
This is a work in progress.
