the way i figure, ive asked many people and they are leaning to the turbo being blown... and with that many people saying it i think to save time just replace the turbo as well instead of just replacing the gaskets... but if we are in the process and notice that the turbo is actually very llose or the gasket has like a chunk missing hehe then yeah.... but from the sounds i dont hear any exhaust leaks... and from help with others it sounds like the turbooooo
