Yes, I did add in one too many zero's.....The noise seems more obvious when I first start out, so that would be at about 1,000rpm. But the noise is there at all speeds even faintly at idle.
I do have a turbo boost gauge and I'm getting 12 at WOT.
I have been looking under the hood and have not noticed any leaking diesel but will check out the return lines and see if that is causing or contributing to the smell.
I'm still going to drive it to work and back throughout the week and see if I can get lucky enough to determine what is happening before something fails.
It warmed up into the 20's this weekend but is expected to go back down to around zero for the remainder of the week. It's too bad that there are no electrical outlets where I work where I could plug in in order to make it a little easier on the engine.
