Asked by for the 1994 Chrysler New Yorker
Agree with first answer,also suggest a combustion leak test to confirm (IF) any internal engine damage. Most any repair shop should be able to do this .
You and I both know it's time to change engine.
It's only ten years old. The 3.5 V6 is a great engine, NOT.

May have damaged the cylinder head when the engine overheated. the overflow could be sign of combustion pressure entering cooling system and high pressures escape on overflow tubes because radiator caps/overflow caps only holds up a certain amount of pressure for the cooling system, and anything over pushes the cap to release in overflow tube.
