Got a question for all of you that have killed the KDP. How many have taken the coveroff and found that the KDP hadn't moved out of its bore?

Seen few before that were stick out just a hair - more than a hair. Had one today that hadn't moved at all. Truck was a 97 12v with 190K and a few mods by the current owner. Previous owner used it as a farm truck and it had a rough life. My friend is currently going through it one step at a time and getting the truck back in better shape. i figured it was possible for the KDP to not move but I just hadn't seen it yet.

 

I did mine at 95k and it seemed it didnt move at all from what Ive read/seen

 

It's not a matter of if, but when. Some go faster than others, but they will almost all fall out eventually. Tab it, and forget it. You could be very sorry otherwise. I picked up a used '96 just under 200k, and the KDP was the first thing I had taken care of, and it was none too soon: there wasn't much left holding it in. I have seen an older 12V that hadn't moved much at close to 300k, but still, it's just a matter of time...

 

AMEN to that, had mine done a month ago, changed the overflow valve also, wow what a difference.

 

i did mine about 3 weeks ago, glad i did it was sticking out about a 1/4 of an inch....

 

i did mine at 270 000 and was only out 1/8 of a inch but glad i did it

 

I've tabbed well over 100 engines and the vast majority haven't moved.
I think a lot of them that are sticking out a little just weren't pounded in all the way to begin with.

On the other hand I've seen over ten engines where the pin came out and caused a wide range of damage including one that needed a new engine.

Anyone who knows about the dowel pin problem and doesn't do anything has more money to burn than I do and isn't very wise.
Sort of like saying. "I've had insurance for twenty years and never used it so I'm canceling."

 

Mine fell out at 79k and cracked the cover.

 

I did mine at 173,000 within first week of buying truck and I could not tell it had moved any. I tapped on it and it went in a little, but it was tight going in so don't know if they just did not get all the way in when engine was originally built.

 

I did mine at 250K and it looked like it hadnt moved a hair. I still felt alot better after doing it though. now i can idle longer and not have to worry about anything.

 

I told him when we were doing it that its good insurance to tab it even though it didn't move.

 

Is there a writeup on here to take care of the KDP?

 

Note to self- look first before asking. I found it.

 

I did mine this spring 123k was about 3/16 out
