Bad demandate

[Oilysnowman]

So update as to where I’m at. Went to the dealership, told me couldn’t touch my truck with it being demandated. So I got running rough to do his magic. Works way better now! Idles smoother, pulls smoother and sounds way better! Still got a little hiccup when I listen to the exhaust, but the engine noise is very smooth listening from beside the engine. so I did the injector bubble test (no bubbles) did an over head adjustment (sounds a tiny bit smoother and in cab vibration went away) but I found some pitting starting on one rocker roller and polishing is different on every lobe on the cam shaft. Insite cylinder cut out test runs on every cylinder but number 2 and 5 lose a good hundred rpm’s more than all the rest. Hoping for some advice regarding that, and I also plan on running this cam shaft until spring when I get a month or two off anyway then replace. Is this a bad idea?
