Hi, I have read odd bits & pieces where it has been stated that these engines (the black-top all alloy ones)cannot be rebuilt. Can anyone confirm if this is definitely the case? My focus has only covered 73k, but I can tell that the engine has developed a faint knock when accelerating that wasnt present when it was younger. I wondered if new big end shells could be fitted to it now rather than wait until it gets really bad & throw an otherwise good engine away? The engine doesnt burn oil, so is otherwise ok. Anyone got any definitive answers please. . . ?
