2009 5.3 engine sqeaking

Hopefully they didn't just change the cam and it lost a lobe..... If it did the engine is otherwise garbage from all that bearing damage. I hope that isn't the case

the tech should really be told you want pics .....before he hands the parts in to the parts dept in a box to be held for awhile untill tossed

Got my truck back from the dealership yesterday afternoon and its running great. There were two bad lifter rollers (1 AFM lifter and 1 standard lifter). One of the lifters started to damage a cam lobe. The other cam lobe wasn't as bad as the one in the picture but it was starting to get scored. I have to give it to the dealership.

Gm and there junk LS7 lifters ( the non AFM ones are what I am referring too). I cringe when people use those in performance builds.... I would bin any set of them and never run them. My 09 2500hds 6 liter did the same thing... and it had no AFM of course. Gm put a new long block in it though.. but it had a dead hole versus just making noise. That's enough material though I would have been pulling caps and checking rods and mains. There likely is some embedded material and scoring for sure. Run it I guess and see how long it lasts.
