There seems to be like there an exhaust leak in between the turbo. This happen last night after i got on it leaving this resturant. But it just real lound and i felt air near the backside of turbo right in front of the block?? anybody know what it can be ??? Dont seem to be boosting to 5psi neither?? So what can it be

 

bump

 

get down there and check your mating surfaces. make your all the bolts are there, make sure the gaskets are in place. i think a visual inspection will help you greatly, and maybe taking a wrench to the bolts to just double check they are tight will help as well

 

sounds like your bolts have backed out on you.... like said above tighten everything up and check everything again

 

well took everything apart it seem to be gasket between manifold and turbo. one bolt compltely gone . The bolt that was gone seem to where the gasket broke
