Not necessarly, the wheels are supposed to have some curl to the edge. Unless it is showing low boost,a funny noise or vibration then there is no need to worry. If you can take a picture of it and post it it will be easier to tell if you have a problem.
Also, I recommend unplugging your EBPV. I did it this weekend, and gained another BIG boost in engine performance. My EBPV must be faulty, since unplugging it also improved performance even when the engine is at normal operating temperature.
Well I tooks som photos but dang if I can figure out how to load tham on this site. any suggestions? enless in some freak way I did get the photo in. in that case it looks like ther blade in the lowwer right is missing a croner if that is so how f up in my engine? thanks j [IMG]turbo2[/IMG]
My connector is in a small cable (2 conductors, I think) at the back of the engine on the driver's side. It hangs around close to the connector that goes through the valve cover gasket at the rear of the engine. One end of the cable runs down under the turbo, the other runs up to the front of the engine along the top side of the valve cover. I just unplugged it and secured the loose ends with zippy ties. Not sure if mine is in the same place as stock, though, since the engine has been pulled and overhauled (not by me).
I just ran out and started it, it's around 25-30 degs. farenheight. greyish brown smoke, not blue. is that what it should look like? I put kwiki's air filter right after I looked at my turbo so thats done. I'm not to sure about my oil consumption, I did not think it was useing much but with this cold weather it seems to be going through it a bit more . Ijust have to keep an eye on it for sure.. the truck has good power. at least
when I re place the turbo wheel I an I replaceing the whole howsing and fan or just the impeller?
Thanks roam and kwik

Ok blue smoke would be low compression and bad rings, so your lack of blue smoke is a good sign.
EVERY intake turbo wheel I have ever seen has a razor sharp straight edge on the leading edge of every blade - no curl. If there is a curl to it I would think that it's been sandblasted!
I've got a curl on every blade and one looks like the corner is broken off. I'm trying to figuer out hoew to get a photo in this post to show yall, but what else shold I look for to know how bad the damage is? thanks kwiki

You need a new wheel. I just put the Swisher wheel in mine a few months ago to cure the compressor stall and the old wheel came out with STRAIGHT leading edges on every blade. If removed I could have cut tomatoes with them they were so sharp. The new wheel that went back in looked a little different in that the leading edges of the blades were staggered in height but the leading edges were straight as a ruler and just as sharp.
I second the "straight and sharp". Mine was sharp enough on the leading edges to cut my finger when I was installing it. If you have anything broken off or bent, then you should replace it.
I the blades are a little curled or a corner missing in will not affect you that much, maybe 1-2 lbs boost at the most, there is no urgent need to replace the wheel. We have run trucks that had this for several thousand miles with no problems.
Well I finaly figured it out. so this is my turbo. all the fins are bent but the one that worrys me the most is the one in the lower left that looks like the corner is misssing.. I is it still rattetling a round in my engine screwing things up? how off balance is my turbo. I dont feel any major vibration from it. my truck gets pretty good fuel milage could it do that with engine damager? thanks for all you guys help. J

The pieces that are missing have long gone thru the motor and shouldn't have been a problem, looks like something other than dust has gotten in there. It appers from the picture that it has been this way for some time it, if you are going to replace the wheel I would have a shop check out the bearings or rebuild it completely since it will be apart already. But it wouldn't hurt it to run it for a while.
