That sucks .....any chance you have a pic of the top side of the lifter ......
....GM is supposed to have a "impoved lifter" from Delphi to fix this issue curious to see what lifter was in your motor ....since it a 2011 ............. hopefully not the Eaton lifters that are the ones with most of the problems .the "validated " new Delphi lifter spring clip on top of the plunger has a 3 sided clip .the old style eaton has just a 2 sided parrallel clip

This is what you get when you go "net build" on your products. GM used to use a "select build" method until 1998 now it is all net build.
Kind of interesting the Arlington SUV plant shut down on Thursday along with all the local OTS's. Inventory levels have fallen. They can't get enough product in time to continue production.
The lifters were the updated versions. Including a recent update on the DOD's. I don't think it was a lifter problem.
When I showed up with a borescope and an alignment fixture the shop foreman was not going to let me take anymore pictures until the GM rep approved them!
The failed lifter bores were .095 out of alignment. Tilted to the rear at the base comparing to the deck. Two others were almost square, thats all I could do till I was stopped. Didn't want to make a scene. Too old for that.

Good news for a change, Dealer informed me GM will replace the engine with new engine. I told dealer when new engine arrives I want to inspect for correct castings. Do not want a parts replacement engine. They assured me it will be new. But they assured me from the beginning there was nothing wrong with the engine it was "normal noises". One of the bad things about all this is the company I work for has a combination of 20 of these trucks between 10's & 11's. Mine is the only one so far with any engine problems.
A couple have had problems turning the headlight lenses brown from heat but other than that nothing. (Those were already covered under warranty)
The only changes so far I have done to the truck is a prodigy ABS trailer brake controller. I am afraid to do anything else. Don't want to void my warranty!

wow i am surprized the dealer took it apart. i have changed cam and lifters on many trucks from 06 to 2011 you are very luckey that they are replaceing the engine. did the lifter boars get dammaged? none of the gm dealers i worked at would every do this for you. they would just through cam and lifter in and thats that. i have changed lifters and cam on these trucks many times and it fixed the prob. the engines are built in seperate plant from assembly. gm has had this prob since 05. i have never seen 99 to 04 have cam and lifter probs. that why i bought used 02 z71. the replacement engine will be the one that is for that truck from gm parts catolog. the only way to tell if its realy a 5.3 is the pistions will be different. 4.8 and 5.3 come with different pistions. the new engne will have heads on you wont be able to tell without borascope. they look identiacal same heads block everthing.

It turns out, after some research and a check with a tech2 , the info I posted is incorrect.
My truck is back to stock and the calibration numbers are correct.
