KDP investigation...
Wanted to share my KDP experience... now I think this pic shows where the pin was supposed to be.
KDP supposed to be here?
This pic shows where I repaired case years ago because of major oil leak. Didn’t know anything about KDP back then. Couldn’t figure out why case was broken and piece was spun around on bolt.
Broken cover
Wasn’t going to buy new cover/case, so just JB welded that sucker and it was fine for 15 years.
So now that my head gasket went, I’m doing a bunch of new stuff, new updated 7 mm head,new stock rockers and stands, HAMILTON beehive springs, Hamilton pushrods, Hamilton camshaft, tappets, Dynamite injectors (not sure which ones yet), ATI dampener, ARP connecting rod bolts and head studs, FASs titanium series lift pump and filter, and bottom sump kit, BE rotary pump fuel pin and 3200 rpm spring, Banks intercooler, bigger waste gate and turbo charger, and want to run tunnel ram intake (not sure if it’s going to be single or dual yet), BD 3 pc pulse exhaust manifold.
If I am not seeing damage to the gears, would that pin have ended up in the oil pan? Would think the piece that spun around could have been getting ground on by the gears, but don’t see anything as of yet. Maybe it shot out when the case broke? Gonna drop the pan tomorrow so I’ll check in there. Strange scenario but I think I got damned lucky. Fix your KDP!

Magnetic drain plug would have found it.
Great save with that JB weld. Never thought that stuff would last that long.

I know right? Some people swear by it. I know there been a few oil changes and I do have a magnetic plug, but don’t ever remember seeing it. I’ll let you all know what I find.

Y'all are scaring me. I've known about this but never got around to it. Ages ago, a year or so after buying the brick I was parked in a lot getting my bearings on direction to go when I suddenly heard this jack-hammer like sound. I shut her off and popped the hood and looked around, got in and started er up and all was as quiet as a Cummins could be at idle. I've wondered if she was passing that pin! I've also wondered why Cummins wouldn't be on the hook for any carnage.

I suspect Cummins covered the repair costs if they showed up within a certain number of years after purchase but we owners are now on our own. I'm told there are hundreds of thousands of 6BT engines affected by this (i.e., not limited to Dodge trucks only) so the cost of a recall and repair would have been prohibitive.

I need to tell a JB weld story, I bought an old tractor sitting in a fience row, I knew it needed alot of work and parts were not available.
The intake valve was open on one cylinder and it was full of crap, it was pitted so bad I would have needed to scrap the tractor as a motor was imposible to find.
I cleaned it up and blasted it with glass beads then using a bondo knife spread JB into the pits, ran a rock hone in it and put it together, still runs great 15 years later, and also my valves are holding up, I ran a bead aroubnd the seat with a stainless rod then ground a new seat, so far it all works as good as new, the old tractor even has 12hp more than it should have.

Not on the piston, but the cylinder walls.
the tractor is a 900 RPM full load 2 cylinder.
My wife had an uncle that had a charter fishing boat in Bradington FL and " he said " that he burned a hole in a piston out in the gulf, as his story goes he pulled the head and cleaned up the hole and JB welded a quarter on the hole and ran it real easy and made it back to land.
I don't know how much spirits were involved when comming up with that but he told it as the truth.

I’m a big fan of using two part epoxy mixes. The key to the success of the mixture holding is in the prep work to the product being fixed, along with properly mixing the two components thoroughly. For years I tried using that epoxy putty, the kind that looks like a sausage and the inner core is one component and the outer core is the other, but every time I’ve had bad luck with those types. Truly the best is the liquid types of epoxies.
For items needing to hold water or air pressure, my go to is Mr Sticky. I’ve found that Mr Sticky is the only one that has worked in fixing the cracks we all get on our first gen front grilles, on that top mounting flange.
