I've seen the term "dusted" quite a bit, and always assumed that it meant something akin to "wasted", "gone", destroyed, etc. Have I understood the lingo correctly?

The reason I'm asking is that I have also seen lots of discussions about the CCV mod and air intake system mods and the varying levels of filtration performance between different air filters. What got me really wondering about this was a comment in Tenn01PSD350's thread about what to look for when buying a 99-03 PSD. He says,

"Inspect turbo inlet side vanes, should be straight and not dusted or jagged..."

Might this mean also that the air filter simply allowed some real dust to get through, and that the dust stuck to oily CCV residue on the vanes?

This may seem inane, but I want to understand this stuff thoroughly so i can take the best care of my new "baby".

Ahead of time... thanks for your patience with my ignorance.

 

DUSTED, term for worn comperssor wheel, wheel will not perform like it shoud due to lack of boost, caused by poor maintenance of intake and or filter. like the open ccv mod i read here this morning, thats a big no, no. from pics ive seen, wheel may look two toned, a dull coloring to mid vane and then a shiny polished look to the outside of the vane, basicly sanding the compressor wheel down.
jagged would be large particles passing through and over time making the vanes very thin and chipping away at the ends of each one. im sure more will chime in with more info than this. but this is my understanding,
---change that air filter rugularly and always check for leaks.

 

Mine looks like its been dusted and even has some dents from something bigger than dust. I am worried, but will deal with it later. New wheel, turbo?? pocket book will decide that one.

I just hope my is ok, I do have 151 miles on it now, but have up-graded to AIS to avoid any more "dusting"

 

Thanks, bigtorque. I have a clear picture now. When i take some time over the holidays to do a few quickie mods, I'm going to make sure to look into the turbo to see what I can see.

 

if you find anything, you can replace with a perfromance wheel or wicked wheel, for less than $100.
it takes a few hours to do, but will be better than the stock wheel.

 

I know that everyone will have their own opinion about the answer to this question, but is there a "best option" wheel to go with? As much as I would like to revert back to my teenager days and mindset and pursue the most horsepower/torque possible, my fatherly and husbandly status won't allow it any more. I will end up pursuing some performance enhancements, but nothing extreme. May not even go to a chip, even though I really want to.

Pete, you make a good point about my post. I should have thrown in a pic or two. I always know what I am talking about, well I think so anyway , or at least what I am trying to say, but it may not always come across that way.
The recent post was one with pics, albeit poor quality of a turbo that the lubrication failed on the shaft causing enough wear for the turbo impeller vanes to walk into the turbo housing. Those chips in the impellar are serious damage. Many things could have caused this. One big chip causing imbalance, then shaft wear, then walking into housing. Failed turbo lubrication causing shaft to walk into housing etc.
A dusted turbo is one as previously described. It looks like it may have been sand blasted. The fins will look more rounded than a clean edge like new. That does not mean the turbo is toast. Far from it, it may still serve many a mile. The point was that this is an indicator of the maintenance and care of the truck. A sandblasted or dusted turbo has passed a lot of particles into the engine. That is the point.

My truck came with a partially sandblasted or dusted turbo. Not really that bad, but I could see it. One of these days I will have a good excuse to get the valve covers off, and I'm going to do a compression check just for the halibut. Happy motoring. Sorry for the long winded post.

 

Thanks, guys, for continuing to keep up the tradition I've seen here at FTE... solid information freely offered to help those who don't know or understand as much... and that without making someone feel stupid for not knowing! I really appreciate your inputs, and am eager to begin applying some of my newfound "knowledge".

 

No sweat Pete, I've learned more here than I probably should have. Now I am in restraint. I think I've forgotten more here than I knew before I came. The beauty is that someone has it or it is here somewhere.

 

I felt the same EXACT way, but I could not say "no" to the PCM tune from Jody- for $75. Hell, I'll spend more than that on a night out sometimes, so its justified. Plus, its paid for itself with the gain in MPG already.

 

In the engineering world, we call that "scope creep", David. I'm sure that I will succumb more and more over time, especially as time diultes my wife's memory of how much all the expenditures amount to. In fact, my older children are already joking about it... "Hey, Dad, which do you want for Christmas... the CCV mod or the HPX mod?"... which is normally followed by... "I bet you actually already have Father's Day and your birthday 'gifts' chosen, too, don't you?"

 

Just simply explain that these are very expensive trucks and that you are mearly doing Preventive Maintenance Modifications to extend the duty life of your vehicle.

It works for me.

 

That's how I've justified what i'm planning thus far. However, it gets more difficult when the mods start sounding like "extra" gauges ( "You mean the factory didn't provide the right thing from the start, or are you pushing the power to a point where you need more information than you would otherwise really need?"), or "larger exhaust pipe" ( "Why? Doesn't the factory one do the job? Is it broken or leaking? Are you just getting power hungry?").... you see, I married a very sharp woman, and she's had 20 years now to learn how to interpret my explanations quite well. If I have something broken, she understands the value of "upgrade", but only to a point.

On a final note.... we also have six "gifts from the Lord" with one starting college next fall.
