Default Reminder: Don't use a truck pan in a mustang swap

last year I finished a ls1 in my 1996 mustang. Ran a best of 12.02 with a wrong tire size..

for a few months this year it served as a DD for my younger brother going to and from school which is <2miles away.

Somehow, somewhere he hit a bump and managed to slightly crack the oil pan.
By the time he got home, he had lost enough oil to score the main bearings.
After taking it apart, I found this as well:




i'm glad it hadnt caused anything. The broken pieces were still in position.

But my main question is this:

while using the plastigauge and checking clearances, I managed to cause this:



my nail doesnt catch on it though. it just seems that the coating got rubbed off when tightening the bolts i suppose?

will i be ok or should i consider replacing them? They are the P-series clevites

Forgot to mention, machine shop turned the crank .010/.010

Might it have been that I somehow tightened that side more than the other?
The engine is supposed to have 66k mi.
Could the loss of oil pressure caused the bores to distort?
