Boone, Iowa | I am repairing this engine that broke the cam. I was cleaning up the engine and found this o-ring on the ground. I thought I would remember where it went, but it’s not coming to me yet. I’m thinking it came off the exhaust side of the block, but I could be wrong. It’s not the small o-ring at the front of the injection pump that seals to the front cover. Any help would be appreciated. Thanks.
