well let me tell yall a story, it goes like this. friday night i was takin my wife out and opted to drive my recently aquired 2000 GT mustang , it ran great all evening into the night, until i made a left turn at the light that was green and i was in 2nd gear i swear i wasnt in or anything, when allof a sudden rattle, clik, clank, bang bam, then nothing. i tried to restart but would turn over (locked up). the car is completly stock but the exhaust. here are some pics, tell me what yall think. its the #2 cylinder, the cause was it broken valve spring.
