so i just got done rebuilding my t2 and its strats up just fine but with in 1 minute it starts to over heat, thick white smoke when i rev it up, and the turbo gets really hot with in seconds of it starting. i just noticed that to coolant level is low and its leaking slowly from where the motor and trans meet so im thinkin freeze plug. so my question is would a leaking freeze plug cause it to over heat like this? oh and the wide band says its running rich...

 

You have a blown coolant seal. If you just rebuilt it, you probably pinched a seal during assembly.

 

freeze plugs only go bad when the engine has water in it and it freezes and has nowhere to go except out of a freeze plug. overheating will cause the radiator hose to blow, overflow tank to spew, or radiator cap to fly off at a very very very high velocity.

like beefhole said, internal coolant seal. i believe it would be the outer seal on the rear of the rear rotor housing that would cause it to leak out of the rear so much

 

great! now i have to pull it again! thanks for the help

 

After you finish fixing the seal, I recommend using Redline Water Wetter... I use it in all my cars and notice a definite decrease in temps!
