Lifter failure
Mine went at 26k and again after the new short block, at 33k. The TSB says go straight to a long block replacement if there is glitter in the oil filter, which is what they did this time. I believe the replacement long block was produced at the end of September 2025 (still trying to confirm), so I am hopeful this one is flawless.

My understanding was there is something stamped on the block or near the oil pan that can be decoded to a date. That being said the engine lift brackets and oil pan both have stickers that say 9-30-25. Taking that with a grain of salt for now. It's been too cold to climb under the truck since getting it back, maybe later this week.
That is a bummer. Haven’t heard of many 23’s failing.
Mine just crested 60k and has been flawless, 8-10k oil changes with a ford filter and Wally supertech 5-30. Gets run hard in MVA traffic, redlined every day that ends in a Y.
If I went thru two engines at 60k, I’d be hunting a clean older 6.2.
Glad you had it covered and good luck with the replacement.

Do you hear any light ticking or tapping even faintly?
It's strange on the mileage failures. It's usually at ~30k and ~90k miles.
Occasionally on startup I get a rattle, usually after sitting for the weekend.
In the winter I will idle it for a good bit, usually working on a Marlboro while on a non-smoking site. Gets some additional idle time in the winter for sure. Haven’t heard any rattles or ticks while idling, usually at the dump I’ll even poke the good ear in the wheel well. Nothing as of yet. Time and milage will tell and I will post and cry about any issues.
One snag I have is a slight squeal from the front drive when it’s below freezing, thinking it’s the one of the alternators or compressor. When warmed the squeal drops out. Minor deal, an issue I’d like my boy at Ford to peek at after the holidays. It’s a warranty item to me and I wouldn’t mind a free belt.

Been super cold so I decided to lube the tensioners before starting. It seems like the viscous fan is my source of noise.
No lifter issues, just a bit of a whine when below 15 degrees. By the time the high idle is over, the noise is too.
I’m effortting to get to 70k before replacing tires, that might be a stretch. To me the most dangerous time to have worn hoops is in the spring with the massive downpours.
Ive never used oil analysis, one of the more experienced users will chime in.

Iron wear is outstanding at .55/1k miles.
Had a light rattle in the bank drive thru (stereo wasn’t blasting). Listened on the way home when stopped, very tinny sounding.
Found the trans pan heat shield loose, it’s kind of a clip on design and after the fluid change it slipped a bit. IMO a shady design, a super thin piece almost foil like. Bolts are m6 so I might dig thru the junk parts bucket and locate a few plastic spacers, in the meantime I punched a hole and ran a small tie wrap between the two at the bottom. Rattle is gone.
Old trusty 7.3 still running great and stronger than a mother’s love.

The early GM LS motors never had lifter failures and there were millions of those motors on the road.that would easily reach 200000 to 300000 miles.Once they went to cylinder deactivation different story. I'm surprised Ford is having so much trouble considering it is basically a GM LS motor.
