rb20det- 5 speed

-- i know i have a vaccum leak- solved that--- car shoots out a grey- white smoke- -- will confurm--- looked up the info -- white smoke- = blown head gasket- , turbo seal - running rich

-- now i was poping a code 54- autoecu- -- it drove fine- then i parked it --- idle funny cuz vaccum leak-- i was driving at night - looked in rear view mirror and noticed smoke- car started dieing at light when i started giving gas--- everytime i gave gas it would come close to dieing-felt like i had no power- when i got home couldnt make it up drive way with out dieing half way - i had to give it alot of gas just to make it up --

coolient line was bent before i cut- it on both bent ends and put hose between- - also for other lower line was bent and did the same-never messed with timing- -- running auto ecu-

could a blown turbo cause this-- white smoke - or could the smoke be cause by head gasket-- and if that was the ? - would smoke be in engine bay-?

need help thanks

Do a leakdown test on your motor to check if it's the head gasket.
