my friend has a 2000 camaro ss auto with 26k miles. we were just driving around raced a little japper snapper, pulled into the gas station after, and on the way home we heard a knocking noise. we got out of the car opened the hood while idling it was knocking. do you guys have any idea what it can be. can it be a broken connecting rod. he doesn’t remember what his oil pressure was at before but it think it is supposed to be at like 40 at idle. now its like 15-20.![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
