NO BOOST! AT ALL!

So i was having problems with blowing my IC boots and whatnot, then the other day after hard acceleration it sounded like i blew another boot...ever since then i have not been able to build any boost.

i checked and the compression wheel is turning just fine at idle., and seems to still have VERY LITTLE shaft play. but i just cannot build any boost, just smokes all over the road and sounds very different. did i blow up the turbo? is it leaking somewhere i dont know of? did i break something else?!

do you have any codes? Pop the MAP sensor line off? Have you built a cheap boost leak detector? Do you hear any hissing?

Its really difficult to say without seeing your truck

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.

no codes...at idle i cannot hear the turbo hissing through the exhaust like i usually do. turbo isnt spooling at all under acceleration. it is leaking at the front of the turbo where the intake manifold bolts up, but ive never had it leak to the point where it wont build boost at all
