so muck truck started knocking and i dont know whats going on with it. it had no loss of poer and no smoke. its sounds like its coming from the bottom end. i pulled the pan and the oil pum and pulled out all kinds of silicon and some metal shavings came out. i check to see if the flywheel was cracked but its not. i played with the rod bearings alittle bit and only have play from side to side. not up and down. when i drive it the nocking stop sparaticly. i dont know what it is. can any body give me some ideas

Have you checked the crank journals for marring, scratches or anything that catches your fingertips?
