Re: Coolant looks like chocolat milk - diagnosis?

Normally, there is no direct engine oil pressure in contact with the cooling system except in the earlier 3 piece engines equipped with oil system heat exchangers. I would be highly suspicious of one of those letting go, especially since the newest one is now 71 years old.

That said, Kev has a good point on possible head gasket. There could be some oil pushed in, and would also help explain bubbling from the radiator cap possibly caused by combustion pressure. I still vote for tranny cooler, very failure prone and seems to fit the symptoms.

Let us know what you find.
