Hey you engine analysts.
I'm installing A Kevco Racing pan right now,
so I got to take an inventory of the contents of the pan and the filter.
I rebuilt this engine (377 Cleveland) last year and put 100 miles on the
break-in oil.
Everything was new or newly ground but the rings.
I kept them because there was very little mileage on the previous build,
(which I inherited along with some very special quality problems).
When I changed the break-in oil,
I got about the volume of 2 BBs in magnetic muck on the drain-plug magnet.
It wasn't very magnetic, so I'll BS-guess and say it was less than 10%
steel/iron.
I didn't recover anything when I tore the filter apart (K&N)
so it was probably just too well distributed for me to find.
Then I put 1200 miles on a fill of Royal Purple synthetic.
I got exactly the same result again with with the drain-plug and the filter.
From the pan I got about a half-dozen chips
about 0.020 x 0.020 x way thinner than I can get ahold of. Maybe 0.002
or 0.003.
This all seemed pretty OK to me.
I think the flakes were one-time sharp edges left from the machine-work.
So - am I delusional guys?
Comments please, I can take it.
