I fell victim to peer preasure at a rodeo this weekend and reved my engine beyond belief. I blew some oil out but I don't think its a big deal... The truck started a small clicking shortly after the event and became really loud on the way home. After towing it back to the house I figured I had a rod trying to come through the valve cover but after removing both valve covers I found that both sides were fine. I cranked the truck and removed the air cleaner and found that the knocking was coming from the carb???WTF It is an Edlebrock 650 (I think) What did I do? Anyone had this problem before?
