Going back to the original post about the article....
I have 2 different mechanical engineers with tons of practical diesel experience both agree (me too, but I am just a troublemaker) that one of the photos in the article is ether mislabeled or being used incorrectly to describe underloading. Now that alone doesn't mean a thing necessarily.
It is the photo of the Turbo wheel that implies it has something to do with underloading. I am getting the feeling and agreement that the photo is of the compressor side of the turbo and what is shown would not be symptomatic of underloading...just crap ingested from the engine room. So I did a bit of browsing about diesel turbo troubleshooting and it all seemed to agree.
So take it for what it is worth...just a raised eyebrow at one part of the article...but like some have slammed others with...if that pic was inaccurate...what else made it past the tech editors?
I also read on the Banks Engineering site (aftermarket stuff mostly for automotive diesels) that having to let a diesel wt turbo cool down after a hard run (especially with synthetic oil) is pretty much a myth. The FAQ was short enough to not explain in great detail...but made it sound like you would have to shut off the engine while coasting down from 100 to see coking anymore....
