Motor blows up at 100,000

[instagator]

I have a 2008 F-350 King Ranch that just blew up a little past the 100,000 mark. To let everyone know the truck went in the dealer ship and came out with new turbos. exactly 2 weeks later the turbos go out again. Finally get the truck back, and a week after getting the truck out of the shop for the second time the motor blows up. Now I was pulling a 48' gooseneck trailer, looked down at the boost gauge and saw that it was fluctuating then out of know where the boost gauge pegs out completely and the motor goes. The dealer ship is saying that I have to pay for a complete new engine, and I am saying no way. Just wanted to know if you guys could help me find information such as the specs for boost on these trucks. Also any other people that may have had the same problem.
Thanks....

Not to cut in on his, but mine didi with the service writer driving and the tech. in the front. Like a bat out of hell like nothing they have seen before- that from both of them (I was not in the truck). What does it mean as I have yet to get any answers.

Not to sound like a smarta$$, but I'm sure most of you diesel owners are familiar with the term "runaway", RIGHT?

Well, for those who are not in the know, a "runaway" occurs when a diesel engine ingests an "alternative fuel source" and increases engine speed not commanded by the operator until BAM!!!!

Since most of you 6.4L owners are now well familiar with the 6.4L's propensity for "making oil" between changes, it's quite possible for oil/fuel to make its way into the CAC quite readily waiting to be ingested, until disaster happens.

Sorry. Thought it meant like it sounds. Truck was never what I expected (no throttle response) as compared to buddies with the same motors, but the tech. said my truck literally broke the back wheels lose @ 30 mph (dry hwy) when they went to accelerate onto the hwy when they test drove it the day I took it in. I told the service writer BS, it has no balls and he said it took off on them- 7 days later they figure out I have 2 melted pistons.

Sorry to play newb here but im interested now. SO, the CAC is holding "alt. fuel", AKA fuel/coolant, etc from what? Leaky heads? Also, how is it getting into this intercooler tube? Is the CAC turbo to intercooler, or I/C to intake? Either way im lost as to how any alternative fuel would be captured in here. Sorry to hear about your motor! Hopefully they man up...

That would be the "alternate fuel" "adding power" Jarrod.
