Sorry if ive caused any panic, if its driving as well as it did before, then im sure it will be fine, i just thought id mention it, as im currently in the process of changing a con rod in an engine that did exactly the same thing, but as i mentioned in my earlier post, it was making a knocking noise every rotation, and i did the steps i mentioned, and piston 2 is 5mm lower then all the rest, so on opening it up, i found the bent con rod, but that engine wasnt running correctly, and was making a noise, so im sure your is fine!
