Thank you sir diesel dude for the quick reply, I copied your answer sa kabilang thread, does this mean we can opt not to replace the nozzle tips when this happens? Yes. Morning hard start is most often not related to nozzle wear.

Since the problem is the driveshaft, sorrry sir newbie sa injection pump, what causes driveshaft failure? I consider this as normal wear. We do an improvement on this area everytime this pump type comes in for service; and we have been very successful in improving the pump's service life.

Sa diesel qulaity ba or the way we drive? No and niether....
