I have a knocking noise and can't determine where it's coming from. Little history - I had the lower unit impeller go bad and it over heated the engine. I pulled the head and had it checked because water was getting in the oil. Head checked out good and I replaced the head gasket of course. Still getting water in the oil. I replaced the exhaust manifold gasket and elbow gasket and the water stopped getting in the oil. Ever since then I have had this knocking noise and I cannot figure out where it's coming from. I just had it tuned up and the valves adjusted and that was not the problem. It has been running like this for almost 10 years and the noise has not gotten better nor worse. Any input would be greatly appreciated. I have a video but not sure how to upload it because it's too big.
