Noticed some gold glitter in my oil filter after the oil change.  Doesn't seem to be magnetic, so I stuck my finger into the drain plug hole and there's chunks and shards on the bottom of the pan.  I can't "pull" any out because the hole wipes it off of my finger when I try.  Feels "sandy" but also can feel "longer" pieces (assumed to be 1/4").  The gunk is gray and I can't tell if it's magnetic or if it sticks to the magnet I used because of hydrostatic attraction from the oil.  When I cut open the filter there was only a speck or two of "glitter" on any of the pleats and no evidence of this gray gunk, and it's been running just great.  No smoke, no loss of power...
It's a 292 from the late 50s and I know very little about what went into the build.  If I recall, it has G heads.  

I have a suspicion that is a result of fuel dilution because I had some carb (Holley 600) tuning issues pop up early in the spring on 2025 that I tried to tweak here and there...when I put on a smaller carb (Edelbrock 500) this spring the plenum under the carb was moist after not running all winter.  Thinking that the gas tank mounted tank had fuel "pushing" on the needle and seat constantly and the ethanol finally rotted it.  

Anyway...what's my next step?  I assume drop the pan and have someone assess.  My guess is that the murky/sandy gray gunk is the teller but I suppose that's possibly part of a bi-metallic bearing?    

There's also the "Schrodinger's Cat Effect" that is telling me that if I didn't know any better, I'd have cruised it all season and maybe not even known.
