Ok finnaly got the pan off and the k member out on my 97 cobra. Found the number 3 cylinder the tabs on the bearing broke and the hearing was spinning inside the rod jurnol. My question is this bearing is only slighly worn mabe a few thousandths of an inch. Is this enough on these engines to make the noise of a rod knock? On the outside part of the bearing there is def wear down to the inside part of the coating in two dime size spots. Im just worried I may have two problems. Found no damage to cylinders no scoring I did find a little bit of aluminum shavings in the pan. Probably just the tabs that broke off of the bearings. Any way Just need to varify the noise part. Could a slighly worn/ spun , not completley destroyed bearing cause a rod knock?
