Turbine shaft nut sucked in engine?
Hey guy's got a weird one for you. I've got a 97 7.3 psd apprx 280k. When I got this truck it was a powerhouse, but power started slipping off. At first it was intermitten and now it is a dog full time. No whooshing sound. Power is smooth, but low. Sitting in neutral pressing the accelerator to the floor the truck struggles to exceed 2250 rpm after several seconds it will make some boost and redline. This generaly produces lots of white smoke. I never hear or feel the turbo anymore.
So with my limited tools I checked for boost leaks, tightened everything, checked the EBPV. Then it got interesting. I pulled the air inlet off to look in the turbo and the first thing I noticed was a couple of blades were slightly buggered on the leading edges. I felt the shaft play and could descern none in and out, but a good bit side to side. Then I noticed the threaded shaft sticking out of the turbine had no nut! After looking at a schematic online for the Garrett 38 it appears there should be a nut there.
Is it possible that the turbine is slipping on the shaft not creating boost? If thats my problem, where do I get a nut and how would I immobilize the shaft to tighten the nut? Thanks. Mike
