2008 MP8 engine

Working on 2008 Mack with MP8 overhead cam engine. Ive got problem where the gear on air compressor keeps getting chewed up. Removed tranny from truck and removed timing gear cover from rear on this engine. Found the intermediate idler (double idler) gearset rubbing into aluminum timing cover. Wanted to know if anyone has come across this problem before.

I've got a 370hp Mack engine in 2004 Granite. Engine light is on and coming up with codes #2 - #5 injectors abnormal frequency & also Engine brake output, current below normal. Anybody experience similar codes.
