while doing some electrical trouble shooting, while the truck was idling, out of no where it started knocking like no tomorrow...

has plenty of oil and oil pressure... sounds like its on the passenger side in either #3 or #4 cylinder... a compression test later will tell...

 

verdict is connecting rod... (X_X)

 

Have you ever done any mods to the motor? Never heard of a connecting rod just giving up like that, especially with somewhat low milage. Are you going to rebuild it?

 

as far as i know the motor is original. all ive done is exhaust and intake... i dont know what im gonna do yet...

about 3 years ago a connecting rod let go in one of the brand new engines we put in my dads boat, had just under 7 hours on it...

 

yup sounds exact same as when my cavalier through a rod...though mine damn near blew through the block...she didn't like to be held at redline...though I still won the race<br>
ahh the young and stupid days
