1948 59ab flathead engine. Engine rebuilt 12 years ago, has run fine all this time, about 25,000 miles on engine. Was time for spring oil change. Normal coolant level. Checked oil and it was at normal height and oil was black on dip stick. Started engine and let it warm up, it ran fine. Loosened the drain plug and noticed clean antifreeze dripping. Drained out about 3 ounces of antifreeze, all clear, then the old oil started draining. Normal dark black used oil, no milky color in oil. Use 50/50 antifreeze mixture. 2 loose head bolts on one side (studs 10,12 middle passenger side) 2lbs loose. Original Edmunds aluminum heads. Oil last changed 12 months ago driven about 1,000 miles last year. Plugs look good.
Car garaged, No freezing temperatures.

Doesn't sound real good. Retorqing the head might have helped.
Try adding 'Stop Leak' or Chemiweld' in the coolant. Beats pulling the heads!
