Hi, my engine is making clicking noises from about 2000 rpm and upwards. since the noise is related to rpm and not throttle opening I concluded that the noise is from the valves, not the injectors. I attempted to adjust the valave clearnces according to the Bently manual - twice. I couldn't get rid of the noise. It seems to me that the noise isn't present when the engine is cold right after starting. Should I adjust the valves again with less clearnce then 0.010 ? Could somthing else in the valvetrain be causing the noise ? Any other ideas ?
