Found a broken blade on the turbo intake fan. See the picture. Could this be the cause of the engine running hotter at higher speeds? What is the recommended way to repair these, rebuild them?
You need to get it replaced ASAP. If it continues to shed blades the metal goes to the blower & then into cylinders. Exhaust side just sheds blades into the muffler.

Get a reman or new one right away. U may have trouble with core charge as yours is incomplete. A rebuilder may have a spare wheel and rebuild yours as well. Lucky the fin didn't stick in valves, which is what usually happens.

I would look carefully at the metal where the break occurred. If it is shiney, then the break is recent and it would be worth some investment in searching fot the missing piece before it goes through the engine. If the metal sat the break is weathered I suspect the part is gone to wherever it was going to go, the only negative if it got hung up in a place where jiggling it would wear something critical over time. Since I no longer have my DD manuals I can't research that, but if I had to guess it would be in the cooler below the blower -assuming the engine is the V92 series. Once you have the turbo off you can do a close inspection of the blower (rotate the engine a bit to to enable seeing all the blower blades. If there are no marks on the blower the pieces were pretty small and probably passed through the engine.
