Heater freeze plug on drivers side was leaking, I could see coolant leaking from it and felt in there and it was loose, I pounded it back in and the massive coolant leak stopped, and there has been no other external coolant leaks.
I added coolant and then waited and could see coolant dripping out of oil pan drain hole.
I added new oil, flushed radiator and added K&W block seal and was able to start and run engine for the 30 minutes. The oil became a light tan milkshake consistency, so there is still coolant getting into the oil, but the engine ran very smoothly with little white smoke from the exhaust.
Could this be the notorious 4.3 intake manifold gasket leak? And that someone added straight water to the radiator and when it got cold that popped out the freeze plug?
Does a bad intake manifold gasket allow water to seep into both the cylinder and oil pan?
