I think I might need a new turbo

The links are to pictures of what I found when I took off the hose and checked out my turbo. My truck has been kind of weak at higher RPMs (low-end torque is still really good) and I suspected the turbo might be to blame. I didn't have any black smoke at high power, though - which led me to think it might be something else for a while. Anyway, when I looked inside, I figured a new turbo was probably in order regardless of it being the root of the problem.

Turbo 1
Turbo 2

I figure the oil is due to worn out seals of some sort. Any idea what would cause the blades to be bent like that? I don't know how something large would have gotten down the intake.

Here's the turbo I ordered - seems to be from a good guy (100% positive with almost 2500 feedback).
eBay Motors: BANKS 94/97FORD POWERSTROKE 7.3 TURBO TURBOCHARGER 1.00 (item 120149569156 end time Aug-14-07 20:35:28 PDT)

Also, should I replace the connecting hoses between the engine and the y pipe? They look pretty old and crusty. Where would I get something like that?

Thanks!

Oil residue in the turbo is common unless you have modded you crankcase vent system. Crankcase vapours vent into the cast pipe before the turbo, yeilding a coat of oil on everthing from turbo inlet to the head intake tubes as it is sucked into the engine.

What about the puddle of oil in the bottom of the turbo? I started up the truck and let it run for a bit with the tube off (while ensuring clean, undisturbed air) and the puddle of oil was still at the bottom of the housing. I would have expected it to go away.

What about the bent blades?

I have ended up isolating this to an exhaust leak (or perhaps a few). The bolt by the #7 cylinder was broken off of the exhaust manifold and it's leaking there. Who knows what shape the up pipes are in - but I'm going to try to work on those when I take the turbo out and replace it. Any ideas on replacements for those? I know there's an International replacement that doesn't require donuts, which is an attractive option to me. I hate repeating repairs.

Any thoughts?

like what was said above oil is normal. the blades are not. they shouldnt be bent. have you looked into geting just the compressor wheel? it's way cheaper than a whole turbo. i havent heard about the IH replacment but if its really out there look into it more. oh, that oil puddle wount go away. if you wipe it out with a VERY clean cloth. and run it for a while the oil wont be there. but when you bolt the intake tube back up the oil mist will start again and the puddle will be back.

Yes International has a fix for the leaking donut gaskets. Black Widow Diesel This are ceramic coated and they also have uncoated ones which you would be able to get from International. I have the coated ones that I need to put in.
EDIT: I just realized I was in the OBS forum. I dont know if these will work on the OBS. Call up Kevin at Black Widow and see what he says.

I found these up pipes for OBS trucks. Kind of expensive, but might be worth it. It's an extra $125 for ceramic coating. Is the ceramic coating worth the $$?

so did you get that turbo? I was thinking about getting the same one from that guy if mine took a crap. I'm curious as to what it's like compared to the stock.
My turbo looks just like yours after almost 300k miles.
