Truck (04 GMC K2500 CC 4x4 Duramax/Ally) just went in the shop. Problems: Speedo went wonky (stuck @ 100 or so), fuel in oil, tapping from under the hood, surge at idle.

Dealer says! -- #8 inj bad, needs fuel pressure reg, guage cluster shorted. Will replace injectors under warranty (Who-hoo!)

Use to do lots of lb7 injectors for fuel in the oil. I also had a hand full of fuel pressure regulators that were slow to respond and would cause a 100rpm surge. The spedo clusters had all kinds of problems in those years. Hope you get it all fixed up. Good luck.

Yeah, those are fairly common problems, but the good thing is GM is standing behin the faults for 200K miles on the injectors.
