Until they soot up and the vains don’t move then you have a low compression turd that’s NA or an NA deisel lol. Diesels are the worst for soot tho rolling coal looks neat but is very much bad high egts and close thing variable turbos see how I jacked my own **** lol
The 2000 K3500 with the 6.5 diesel I have was having issues with the turbo, it is an electronically controlled wastegate.
New vacuum pump, new boost control solenoid and it works wonderfully now.
EGTs was up over 1200, I was very concerned about those numbers, found out that they will withstand 1500 degrees for hours, not so concerned about 1200 degrees anymore. LOL
I have not had it on a pull since getting the wastegate to properly function, just guessing, it now will probably be in the 900 degree range.
Nice thing about having a properly functioning wastegate, no more coal. LOL
