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.

I removed the fan hub and radiator on mine as well. It made work easier.

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? |

Here's an '02 that had the KDP take out the case. This is not a second hand account. This is my dad's truck.
There was a hole punched in the usual place and the pin was mangled. Attachment 59124 Dave |
Youre scaring me Dave - My 98 is done but I havent looked at my 01
Lucky that was a warranty repair... |

Lucky that was a warranty repair... 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! Dave |

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 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!!!
