yep ya heard right it started on fire......

was headed home from up north 2 weeks ago, weather was cold about -15*F...dropped off a friend went to go up the on-ramp, could tell the truck didnt have quite the power that it should....thought,hell, this thing is gellin' up....could still do 70 mph just fine...made it to the next qwik trip, threw in an bottle of 911 and topped it off with winter treated diesel...continued on my way.....still ran idled fine, no issues other than just not havin all the power it should.....was going down the highway and it was like it shut off....put the 4-ways on went to pull over and it came back to life.....back up to 70mph....thought maybe it passed a chunk of gelled up fuel and shes fine now.....made it another 20 miles down the road and it cuts me down to 45mph and wont go any faster.....put the 4-ways on and continued for about 4-5 miles to the next gas station...pulled in...put it in park and a huge cloud of smoke came from under the hood...popped the hood and comin from the passenger side of the motor my exhaust manifold and turbo and glowing red/orange hot! and melting anything close to it...one hose started on fire and i blew that out myself and it proceeded to melt thru my coolant resivoir....coolant all over.....and thats where it sat.....i found my ride home and they towed it to the dealer the next day...

my coolant was about 205* oil temp was about 210*-212*, outside temp was between -18* to -15*....i had my weather front on....was pulling an enclosed aluminum snowmobile trailer with one sled in it....so it wasnt gettin worked by any means.....2014 2500 cummins...has about 26,000 miles on it...totally stock other than a k&n air filter.....has had a pretty easy life....only highway miles and pulling a snowmobile trailer.......

the dealer has no idea what went wrong, all they did was replace the melted parts hoses ect..... myself i think there has to be alot of compromised parts in the turbo/motor that got too hot myself.....anyone have any ideas or heard of this happening before? thanx

That seems very odd that the manifold and turbo got that hot but your coolant and oil temps were fine. Was it making any whistling noise like it does with the exhaust brake on when you were driving? One problem can be that the exhaust vanes in the turbo get stuck either open or closed. So if yours were stuck closed they wouldn't flow air very well at all and could definitely create some heat. That would also explain the reduced power that you were feeling. I'd also check for a leaking injector. If one was leaking and dumping raw fuel into into the manifold that would obviously create heat as well.

I'd be monitoring a few things in the mean time. EGT's and boost pressure while driving for sure and I'd be checking your oil quite often to see any signs of burning with the turbo getting that hot.

the dealer has had it for 5 weeks now and just today they finally called me with a diagnosis..."supposedly" they say that it was fuel contamination....which i think is a buncha crap...i have talked to 15-20 diesel guys, including cummins, power service, diesel forward, truck county, mack, and other dodge dealers....everyone except the dealer it is at says its something else NOT fuel....if i told them once i told them 100 times that it cant be fuel......taking it to a different dealer this weekend.......anyone have any ideas?

Almost seems like the turbo was maybe not getting oil. You have like 2 fuel filters right?

Greetings, I had this happen to a gas motor a few years back but it was the catalytic converter that was red. Put 2 cans of STP Gas treatment & topped of tank with 93 oct. & back on the road. the guy at station said I had water in fuel. I had just fueled up when this happen... Good Luck..

The stealership will always search for a problem that "you"were a cause..I say Brandon is close to the issue either the VVT was closed or Turbo was stopped those temps were very cold to say the least run from that dealership if theyre trying to blame you get a specialist involved. They can get a fuel sample and do a calorie test on it to see if were contaminated did they pull the filters?
