Just when I think I have the flow figured out, it changes. I am 71 and too old to follow. Requested pics would help.I believe it was the plug he was referring to that had the shavings on it, and maybe he cleaned it up. Hard to follow all of this.

Yes it’s the oil pressure sensor unfortunately yes the timing was severely out of wackIIRC 1996 and certainly later engines used a crank trigger to control the timing, so I can't fathom how the timing ever "jumped"... unless the distributor somenow got turned SO far out of spec that the spark was jumping to the wrong tower in the cap (and thus firing the cylinders with grossly advanced or delayed timing).
Otherwise, distributor only plays a subordinate role.
See https://www.gmt400.com/threads/98-5-7-k2500-timing.66119/post-1386186 and the posts there.
I assume the "sensor" you mention here is the "oil pressure sensor".
No it was just shavings on the drain plug one of the bearings are beginning to make noise on the front of the blockI am sorry, I am completely confused. can you supply pics? Threw the bearing away??????
