i love these stories. Same thing happen to me and #3 bearing lol. jiffy lube oil change one day later oil light and boom. lol.... they paid for it.. said it was low oil and the good thing was the bottom of the block didnt blow out so i was able to prove the oil was low at the time.
the second motor installed blew into pieces so no telling how much oild was there.
good luck and keep fighting for it
