Well friday while replacing a electronic pump on a 98. 5 24 valve cummins I decided to check the KDP, I have heard that cummins fixed the problem for the 98's but I wanted to check, Well the dowel was out about 5/16 of a inch out of the cover hole. It was getting ready to fall!!!! I tabbed it and if any needs to know when the engine was built, it was 5-28-98, Never been apart until the pump went out!:--)
