Alright guys. . . .The car runs great with no overheating, with the car running there is no leak. As soon as i turn it off yo can hear the pressure pushing out some where by the turbos? It only leaks for a few min then it stops? Any ideas?

 

Pressure test the coolant system and trace back the "hissing".

 

Check your turbo coolant lines. If one of them is leaking, it may leak on the turbos, and evaporate before hitting the ground.

 

it might be leading from the coolant to Throttle Boddy line, also.
