Advice on engine replacement

[2Cool2Fool]

I’ve got a 2016 Yukon with 128k miles. I’m pretty sure I’ve got a collapsed lifter. The problem started with the engine seruosly bogging between 1000-1500 rpm - and within less than 10 miles - it was making a very long tapping sound under the drivers side valve cover any time the rpm’s drop under 1000.

I talked to the local shop, and he said it sounded like DOD lifter. He said that if they confirm that I that as the problem, have two choices: have them do a DOD replacement - or buy a Deleted rebuilt long block. They said that at 128k miles, doing the DOD replacement is almost as expensive in terms of parts and labor as a rebuilt deleted long block.

Anybody have experience with this and the name of one or two reputable long block rebuilder? Thanks

Or, drop a 6.6L L8T into it and get some basic tuning done. No more AFM parts to worry about.

Option 2, regardless of whether you replace your engine with a 5.3L, a 6.0L, a 6.2L, or a 6.6L.
You might be pleasantly surprised when you find out how much a 6.0L costs, especially compared to the 5.3L.

L86 to L8T in '19 Yukon XL Denali

After reading through @L8T BURB thread, I decided to swap out the broken L86 (Thank you GM DoD) out for the L8T. So far smooth sailing, separating the l86 from the 10l80 required a wood chisel to wedge in and work around the block until they separated. Now that the new L8T is set in place there...
