[V8] POP..Hiss..Smoke..Antifreeze Smell..SOS!!!

[Ingo Rautenberg]

Hmm.  Sounds like the nightmare I recently went through.  In my case it was
the heater core (as pointed out by Mr. Head) began to disintegrate, lodging
plastic pieces into the return hose nipple of the expansion tank (clogging
it) and leading to calcification of the radiator internals, reducing
radiator efficiency to nil and causing failure first of the heater valve and
finally the heater core.  If you're lucky, maybe it's just the heater valve
(but your passenger side smoke description makes that unlikely).

Good luck and let us know what you find.

Ingo
