Truck consumed 1 gallon every 12,000 miles up to that point now was 1 gallon every 4,000. Fast forward to now at 670,000 started pushing 1 gallon every 2.. parked it and got it cracked open.

Found that the rebuilt turbo from Chicago is shot, not shocking at all I know.. Engine, #6 was polished on the top half of the liner, all the rings were carbon packed. 1 or 2 injectors have a bad spray pattern outside the bowl on a few nozzles the rest were perfect within the bowl. Block is getting cut to 14 thou with stainless shims. However my guy ran into an issue removing the cam he said it got stuck about halfway out and had to be pryed out. Found the cam appeared to be bent when placed on his table and noticable lack of wear where the roller skipped on the exhaust lobes from being too loose on adjustment?? Anyone ever ran into this? Going all OEM on parts by the way including new oem head.

I would be looking for someone that was better skilled on the ISX if a mechanic told me those things.
