Does anyone know of any type of puddy or somthing like a thick jb weld that could withstand our motors exhaust temps goin into the turbo my donut gaskest is bad and I cant figure how to replace without taking the motor out and the new pipe is like 140 bucks. So i was hopin i could seal if off with out goin thru all that trouble. But I want to seal it off best I can beause Im sure thats effecting my boost.power.milage everything And if im gonna do exhaust turbo back intake chip and possaibly propain, but turbo isnt working right might not be worth it at all.huh just wonderin if anyones ever done anything like this before .

the only way to fix it is to replace the pipes and donuts. Sometimes the bolts for the flanges also break in the manifold that bolts to the turbo....causing the need for that manifold to be replaced as well....

You dont have to pull the motor, but you do have to pull the turbo. I do them without pulling either, but i did quite a few pulling the turbo before i felt comforatable doing it the way i do it. Pulling the turbo would be the way to go. That pipe is too smooth and hot for any kind of epoxy to hold up to....

Another note, with that pipe leaking, you are losing turbo boost as well since that is before the exhaust gas drives the turbo...less exhaust driving it equils lower boost pressures...
