alright so about a month ago my car cut off on me in the middle of the highway. i heard some noise that i thought was my flywheel finally going as i was having clutch problems. i cranked the car again and its started, heard what sounded like loud scraping, and the car cut off and never started again. when i took it to the mechanic they said i blew the motor due to lack of oil? so i ripped the head off the block and took some pictures of the top of the block to see if anyone could help me out int telling if the diagnosis of the problem was correct.
