KDP Question
OOOHHHH NO, It's andrew. As I live and breath. I don't know about the 12V cover not fittin the 24V but I did finally after all the years of talkin about it pulled my cover a few months ago. On my 99 it was not the improved version that holds the dowell in. I got lucky I suppose. 200,000 miles and the pin had not budged at all from where it started.
If you do some research, you'll find it's more than just the case. Yes, the old case allows the pin to travel outwards, since there is no shoulder, but in the 12 valve engines the weight and vibration of the injection pump is what also contributes to the KDP. You don't have that problem with the VP.
One last thing; I dare anyone to take a casing from a 12 valve truck and use it on a 24 valve truck with a VP, it just will not work. Therefore, the casings are different between the two applications ... for what it's worth, since I know I'm starting an argument ... right doctor?

How do you explain people finding their dowel pins have moved on their 24Vs?

Mine was the upgraded model. My dad's was not. I bought my truck from the same lot he did and his build date was later than mike. Also, the same factory produced both trucks.
For the cost of a seal, a tube of RTV or Permatex and a tab, it's cheap insurance for anyone to check it out IMO.
Most likely, most guys will never have an issue. That's just not how my luck goes!

Darn it, Doctor, you got me again! 
I must turn my attention to the year of the truck. This is a first and you'll have to agree with me on that. Not to mention, this is the first valid piece of evidence I've seen that a post '98 (12 vavle) truck has had a problem.
In my earlier post, I was laying out, exactly, the explanation given by Cummins ... which makes perfect sense.
So now we are saying ALL 2nd gen trucks have the KDP problem ... that's scary!

I would say no, but assume that they do. Until that cover is pulled, no one would really know.

I am really close to pulling everything on mine that is needed to do the KDP tab, even though my truck has 278k miles and counting (263k when i bought it). I am just paranoid, even if I pull things and it is tabbed already, will make me sleep better at night!!!
