This is going to sound weird, but I've read on a couple websites with your problem was solved by changing sparkplugs.
Apparently, the sparkplugs in the vehicle looked fine and had spark but it was not adequate.
Obviously, I can't verify this personally, but it would be a cheap try.
I have had changing plug(s) solve similar issue with some of my motorcycles and small engines in the past.

starting new MYTHs or supporting one. hahahahahaha!
If you find an empirical Data supporting that information let me know so I can call Dr Christopher Jacobs, PhD.E.E. and tell him he was wrong about how sparkplugs work.... LOL

The last rod knock i heard was on a Chevy 292 I-6 in 1997, so i doubted my own ears. Don't know the 2.5, but with cam lobes so pristine, no sludge, and a good service history .. just second guessed myself that a low mile Jap four with perfect compression could have shat it's bottom end - so pulled the pan. Absolute "golden spray paint' hell with chunks. This is a very dead engine! Although I wonder what exactly killed it.

Wrecker plant with 152K arrived on a pallet today.

EDIT .. been bugging me all night. As i said, I'm obsolete .. when i pulled the pan there was a chain driven thingy on the crank girdle spanning three cylinders- behind/adjacent the oil pump, I have no idea what it is and that makes me sad. i was a god once. Guessing that's the Skyactive flux capacitor.

Regardless, all reciprocating IC engines still do what they did in 1889.

Clearly the bottom end was oil starved .. but not the top. Why?

Memory fading .. but something vague with the Ford Windsor .. the way the oil galleries were arranged .. if a lifter collapsed, the bottom would starve. Or probably just read that in a Peterson rag.

This is probably an anomaly .. factory worker 5 years ago recovering from Saki installed the wrong bearing shell?

When my POS Crown Vic tosses a rod, I'll know why .. She's 15 with a quarter of a million after hard cop duty, driven like stolen, I'm lazy and that oil is 12K old. But I can't wrap my head around why a modern engine with love has self destructed so thoroughly. Rhetorical i suppose mid St. Patty's and a few cups.

Lobstah .. I like your handle. A few years back i did a now deleted (truth .. it just sucked) Youtube series that no one watched as "The Lobster Claw" .. Fine electronics work, oddball projects like a Nixie tube tach, and manual paddle shifter and display for the 4R70W, and soldering in an unheated shop at minus 20, lol. get it?

Well she's out. With the AWD transfer case/brackets in the way, a few of those bellhousing bolts were a challenge to find, let alone snag, and man there wasn't much space to play with the crane. Not looking forward to doing it backwards today quite the same as if .. Oh, I dunno - waking up to Kate Beckinsale making coffee in nothing but a straw hat?

Kind of laughing actually; fond memories .. I didn't bring my kit, and so got 'er done with some of the lousiest basic tool set I've ever seen rolling around the boss man's shop. But I've never been a tool snob. The guys I used to share a bay with when i modified vehicles for accessibility used to joke about that, with their hundred grand roller cabinets full of Snap-offs .. then they shut up when i showed 'em how to shrink a bearing out with a welder in 120 seconds flat.

Now trying to consider what i want to dress the wrecker plant with .. it apparently has 152K on it. Doesn't look like they played forklift soccer in the yard, and didn't just hack the harness. Don't really think I need to swap anything over but the missing alternator and buy an exhaust mani gasket. i swear i remember thinking they used to dynamite them out at the boneyard once.

The doner is 2015 .. vehicle '17 - but appears the same down to the harness plugs and tooth number on the flexplate. But I've done a few too many teen Fords lately where they think it's funny to change every plug form factor or wire position every year. Should this be plug-and-play, or is there something I may need to know?
