So I have a 1994 7.3 Turbo swapped into a van chassis (1987 motorhome actually), and last fall the turbo started to make a whirling/squealing noise when you really giver throttle. I'm not eliminating the possibility that it could be a belt or something else, but it has always sounded like it's coming from the right hand side of the doghouse. I also pulled the doghouse off yesterday and went for a spin and it still sounds like as the turbo spools up, that is where the noise is coming from. The noise also disappears, as I let off the throttle (and the turbo PSI returns to 0). The noise isn't always the same pitch depending when I give it a lot of gas....
I took a video with the noise that I'll try upload somewhere if people think that'll help.
Last thing, I took the inflow air off yesterday (by the orange boot on my rig) and tried to wiggle the turbo fan shaft. It spun fine, but it felt like there was (very small, but observable) amount of play in the shaft up/down, left/right..
Any thoughts if you think it is the shaft? What to do / check next?
Video should be here:
