Ive seen a handfull of failed lifters. Not enugh to say its common.
I would also think you would of had a noticable misfire worse when cold.
I wounder if the first repair attempt did a blowby test?
also its possible that its not a melted piston at all. it could very well be a valve not sealing. been down that road.

nope. Not even with all the MICU's that we work on. seen less then 50 low side pump failers too.
on the flip side I heard once that broken crankshafts were common. Ive seen one and that was caused by a bad case of dumba$$

Fella's I really appreciate these discussions. If this is a valve issue it will save me a ton of coin !
Talking with the tech (after he replaced the #1 inj) the truck will fire up when cold no issues (actually thought it was fixed). Go to start it 10 minutes later it will rollover a few extra revolutions then fire. It will miss for a little bit than run okay. To drive it he could tell there was something not quite right.
Note : Before I took it in I had pulled a 12000lb trailer for 500k and it ran good - good power with no smoke when warm. Starts fine when hot (no smoke).
Any thoughts ?

adamtheman16 is right on the money cause when the injector tip blew off mine the wife was in the passing lane and thats where the truck stayed, instant failure, truck shuddered puffed black smoke and shut down all within a 1/2 km, I know if my 6.0 gives up the ghost now that it is off warrenty it will be a cummins under the hood after that

Here is where i'm at
1) New (used) motor with warranty is 5G.
2) New crate is $6500
3) Replace piston $1000
4) Replace piston with re-machine cylinder is $3000
5) Cummins swap $9000
These options don't include labor. Quoted 25 hours (so add $3000).
Leaning towards asking the guys to pull the head and report back on what they find. If the cylinder is scuffed I'm going to push the truck off the edge of a cliff.
Hoping someone had a similar experience as to what caused the failure and what is the possibility that the cylinder wall and the rest of the motor will be okay.

Cheezit - want to thank-you for your help.
After talking with Blackwater engines and your advice I decided to hold off on the engine repair and drive it till she blows. Highly likely the cylinder is damaged.
I'm into a new motor anyway so put the skinny pedal to the floor and hope for the best.

Hey sulley, how did it work out. Is it still running? Anyone know how this came out? My truck sounds kind of like the youtube video. I know I have a couple miles, and I have defended the 6.0 for over six years and over 850k miles, but a catastrophic failure before half a million in a diesel, especially since 3/4 of all those miles were fairly easy at 58mph. The blackwater engine sounds good, but 50k warranty, sounds like they will cover it as long as it sits still. I'm freakin upset. I've always heard and thought the lower end of the 6.0 was very reliable. So we have sub par top end, and a sub par lower end. I have never posted anything negative about ford trucks, so I am not trying to be a basher at all, I just need to vent.

Not arguing. It is frustrating to see things like a DieselPowerMagazine article throw out a statement that 6.0L's suffer from broken crankshafts and suddenly everyone believes they have a ticking time bomb. People are quick to react these days and then rumors spread. BTW - this is not referring to you run6.0run. That article and its subsequent responses happened a few years ago and finally died down (thankfully). The evidence is that the lower end is quite reliable - unless people expect unlimited miles ......
