For the leak, do you have a boost guage? Any boost loss? Check that egr crossover tube that runs from the egr cooler behind the motor, it's just a rubber style hose that likes to blow out.

Injector cam? or Cam injector? I dont know about those. Is it maybe a stuck injector or something or have something to do with the cam shaft? But thats exactly what its doing. Rocking the truck side to side so to speak.
