Is my turbo on its way out?

I have a 95' powerstroke. I'm not sure if my turbo is on it's way out or not, it seems to have quite a bit of play in it (up and down). The end play feels ok I think. Does anyone know what the end play/ up and down play tolerances are supposed to be?

Also, my turbo wheel is kinda screwed up, looks like something folded over the outer part of the fins. I've been driving it like this for about a month. But anyway, lately the truck has been acting up. For instance; when's it's cold, for about the first 50 feet of driving it doesn't feel like the turbo is spinning, it loses tons of power and sounds different. But after driving it 50 feet or so you can hear the turbo spool up and it runs normal, it foes ths every single morning. Today it it ran ****ty like that for about 20 minutes and once it got hot it seemed to run normal again.

If anyone can shed some light on what could possibly be the problem I would appreciate it! Thanks

The wheel at the outermost part has about .030 up and down play in it. The wheel does not rub on the housing.

post a pic of what your compressor wheel looks like. its hard to tell what you mean without pics

my truck does the same thing when its cold, the first 50 feet it dosent have get up and go but the the turbo spools and it goes.
i figure it does this because the ebpv is closed then finally opens allowing the turbo to spool.

Wow, thats impressive. Havn't seen that before...Give me a min to take the picture in and ill get back to you o.0

EDIT- after looking at the picture a little more...the fins are so perfect except were they are bent or broken that Im guessing its hitting the housing and thats what caused it.

Try to see if you can push on the shaft, spin the compressor wheel and see if its contacting. If it is then it need to be addressed, most likley at this point you wont just be able to rebuild it? im no expert but ive been down this road.

That wheel is terrible as far as I can tell.

It looks like they are all bent over? and maybe even a few are completely broken off?

I dont know if this is from the wheel contacting the housing, or if a bowling ball slipped through your airfilter and thats what caused the dusting we are seeing.

Something is very wrong, Im going to assume you dont have a boost gauge...because I doubt your building any.

Ill upload a picture of my old dusted compressor wheel and it would only build 8lbs of boost, after swapping turbos I am able to get a solid 20-22 psi now. Nothing different except a new compressor wheel.

that has chipping on the ends of the wheel, yours look to be completely busted off, or bent? either way maybe someone else has seen it....I might be wrong and it might not be an issue? but uh..lol

When I got the truck the air box was all broken, I guess the guy I bought it from put too much ether in the intake and it backfired, my guess is that I sucked in a piece if the air box or something.

Even when the airbox is all together, its a POS. Get an aftermarket one..cheap way out like most people do is go to napa and get the 6637. You will need a little pipe to get it all clamped together.


haul the turbo apart, check to see if the compressor housing is Fed up, if it is I have a core if needed (needs to be rebuilt)

if not, just throw a rebuild kit and a wheel at it. you will be back in business.... and get the glow plug system straightened out so you dont have to be putting ether into her

I bought the truck as a basket case. It needed a new glow plug relay which is why ether was needed evidently. And it needed 3 injectors. I put a new air box on it too.

The turbo I think is in good shape, just the wheels ****ed up. The compressor wheel does not run on the housing. Ill look into getting an impeller, thanks for your input!!

oh, if shaft play is in spec and everything checks out. Toss a new wheel on it and everything should be good!
