Car: 88 'vert with rebuilt 88 turbo engine (~6k miles after rebuild), tranny etc, running stock turbo and boost etc.



Backstory: I was merging onto a highway earlier, accelerating from 2nd gear, and suddenly white smoke starts pouring out of the exhaust and engine bay. I shut it down (it didnt overheat) and pull to the side of the road to check it out. No leaks from any of the hoses (none of the main water hoses, line from water pump to BAC, BAC to rear iron, or heater hoses), so i get it towed home.



Problem: When filling up the coolant, its literally pouring out of the joint between the rear iron and the bell housing as fast as I pour it in. Is there anything back there on the rear iron that could be leaking this badly (main E-shaft seal, drain plug, something?) or is this a cracked rear iron? I had about a 50/50 coolant mix in it and never had trouble with overheating before. The car hasnt been sitting, and it hasnt been cold enough to freeze the coolant mixture.



Please help, this is my only car, and i need some way of getting back to MI in a couple days! Thanks in advance!

 

Freeze plug

 

Thats what it sounds like a freeze plug if its leaking between the tranny and rear steel but then againg you said out of the exhaust also if its coming out of the exhaust and rear steel more then likely its the water seals or a crack rear steel .

 

well, i couldnt actually tell if it was coming out of the exhaust, i just noticed the smoke behind the car and coming from under the hood when driving. Where could i buy freeze-out plugs, and what size are they?

 

You need to drop the tranny first and inspect the rear iron. It does sound like a freeze plug, but you need to be certain...
