2014 Silverado lifter issues
I have a 2014 Silverado with the 5.3L V8 that I bought brand new 8 years ago. The tow capacity is 9700#. My travel trailer dry weight is 7500# and fully loaded for a trip, I’m guessing I’m between 9...

This is your lucky day. I just went through this with my 2015 Silverado 1500 5.3L. Had a lifter seize at 141,000, my mechanic did the recommended repair, replacing all 16, and 500 miles later just rolling up an on-ramp, it did it again.
This is when my mechanic found out about the VLOM.
Did the shop change the "VLOM?" Valve Lifter Oil Manifold. This is the module that controls oil flow to the AFM lifters. It can malfunction and send/withhold oil to the AFM lifters at the wrong time, causing the seizing.
I suspect it was not replaced.
If it was not, it will keep sticking lifters again and again and again.
Unfortunately VLOMs are IMPOSSIBLE to get right now. Because of the lawsuit over these engines, my understanding is GM terminated its contract with the manufacturer of these modules, AND they can't convince anyone else to make them, because of the lawsuit. They are out of stock everywhere.
This truck has never towed anything heavy. It is not how you're using the truck.
Wouldn't the Range AFM disabler module I have plugged in prevent the problem with the VLOM?
