My KR readings today
Hooked up to a Snap-On scanner today due to some noises that are not exactly nice.
In Park I lightly revved the engine to about 1200 rpm.
After about 1 second the Knock Retard jumped from 0* to 15*.
Advanced Timing went from 35* to 20*.
I let off and the KR dropped to 0* and the advanced timing went to 17*.
I then revved it to 1500 rpm and the timing jumped to 35* for a second and the Knock Retard showed 23* of KR.
Yup, that definitely is a main or rod bearing. :(
In a way I'm glad it'* not my car, but I'm sad to say it is the 1997 Park Avenue I bought and traded to my dad who sold it to my uncle and aunt.
Luckily I found a motor out of a 2002 Lesabre with 49k miles that is 130 miles away for $250 and a call to a mechanic friend got a install quote of $250 + any coolant, oil, filters, etc... which would bring the total cost up to around $575-600 to get them back on the road so they can visit their daughter in Manitoba in a couple weeks.

If it'* a rod knocking, it'* loud enough it would more than likely wig out the Knock Sensor...

On the Intake manifold'* (went from passenger side runner to runner nearest the TB) and the noise was more audible the closer we went to the TB.
We pulled the plug wires and found the 1/4 coil to have very rusty connectors so we cleaned those and the spark plug wire connections and that didn't change anything. I pulled the 1 and 4 plugs and they look good.
He said false KR wouldn't be that high if it was coming from outside of the block unless it was some really heavy knocking on the block, which would be audible to the ear, especially with the hood open and someone over the engine like we were.

Sorry to hear they are having that issue with the car...
Mine had some Piston slap... I think this was caused by an issue with the wrist pin bushing and wrist pin... Beat the skirts up over time and the KR was uncontrollable as the Knock Sensors were going nuts... The 2nd motor spun a rod bearing and drove the sensors nuts as well..
Either way I hope the 2nd motor will serve them well
