a link with info about an 02 in which the kdp came out and caused damage.
i've seen 98.5s with old style case and revised. and i've also seen 99s both ways. being they didnt put the old style in the scrap pile as they should've i can see where occasionally the old style may have been slipped in on newer, thru 02 engines.
of course nt a posibilty on 03s as that is whole new design with the cp3.
so if you have a 99 or earlier check that pin. living on borrowed time if ya dont. if you are wise and have an 02 or earlier you will do the same.
may not need it on the 00 thru 02 but why take a chance.
