[QUOTE="ytradio, post: 437160, member: 19779"] Just my opinion, but I’m not sure how you ruled out the rod and main bearings but that sounds to me like the most likely culprits. If it were mine, and remember it’s not, I would put a heavier oil in it than whatever you are running now and see if it takes a little longer for the knock to start. That would indicate (to me) to start on the bottom end ( crank shaft). Again just my opinion. [/QUOTE]
