Are all 12 valves affected by the KDP? Is it specific to certain years..?

All Cummins B series engines up to '00 model year are possible KDP candidates. PM me if you want yours taken care of.

Is that up to AND including?

Yes. However, I've done 2 '00 trucks and they both had the updated timing case. You can tell because the drill bit breaks through and then hits more metal. I've done a '98 24 valve, and that had the old case. Haven't doen a '99 yet. Seems to me that it's not real likely to happen to a '00, but I do 'em anyway just for the owner's peace of mind.

Just killed mine today. It was sticking out past the edge case about a 1/16"-1/8". Drove it back in and peened case so it can't get out.

1989-99.

The 2000's already have the updated case. The updated cases were going on during the 1999 model year.

Well I tabbed my 1997, but it looks like I don't need to worry about my 2000.
