This oil in the water started out as a black powder at the overflow outlet but progressed with the season to liquid oil turning the coolant to sludge. More oil seems to leak the hotter I run the engine. It does better if temperature is kept below 190. I did have the overheat buzzer go off twice last year, lost track of gauge. It turned out a fitting had fallen from the intake manifold and I was losing boost, lots of black smoke and probably high egt. It took me a while to figure this out, probably 200 hours at least. Tractor is used to run a 21ft flail mower.
I have heard of porous blocks on earlier Fords, but is this possibly the culprit in my 1995 year tractor? The engine is a BSD 444T.
I did pressure check the radiator, and it held pressure even while running--no pulsing. I also pressurized the oil cooler (plugged one side) in the radiator when the pressure gauge was hooked up to radiator, and I got no increase in the radiator pressure, so that tells me the $1500 radiator is good.
My first instinct is to pull the head off this thing, and hope for a blown head gasket, or worse a cracked head.
The machine is right at 3000hrs, and runs great with good power
Any thoughts?
