Blown up commonrail
 

Ok, so yesterday i was following a dodge 3500 dually commonrail down I-79 doin about 75mph. I was in my truck, he has a car trailer with 2 small SUV's on it. Completely out of the blue this truck goes up in a cloud of white smoke, and one of his trailer tires blows apart. So he gets control of the rig and pulls over. Since i know the trucks semi decent, i pulled over to give him a hand. Theres white smoke barreling from out of the hood, and when we popped the hood, everything was covered in oil. So i crawl underneath and theres a baseball sized hole in his oil pan and the only thing leaking out of the pan was diesel fuel..... Interesting... Catastrophic engine failure if you ask me. So apparently he blew parts through his oil pan, which in turn blew one of his trailer tires. The truck had 120,000 miles on it. I love cummins, but i may be scared of the commonrails now... So i offered to pull his truck, along with the trailer and the two cars to the next exit which was a mile away, but then ended up not doing it due to the fine that goes along with using a tow chain on an interstate. Thank god i didnt pull him because there was a state cop setting up flares getting ready for construction on the next exit's offramp. But anyway, i thought this was an interesting story that i figured i would share.

Thats crazy...I wonder what would have caused that...

Maybe a stuck open injector.

I don't think I would be to scared of the common rail. There still a great engine thats just kind of strange but I guess you build enough of something a bad one will come along.

Who knows how the engine had been treated for those 120k miles. Now as for something coming out the bottom of the pan.....thats scary. Who knows though.....maybe main cap come loose, and let go at 2k rpm.

Yeah. I found it kinda shocking. Never really seen that happen to one of these motors running stock. I can see at crazy boost pressures or whatever splittin the block or blowin heads but a stock truck without upgrades blowin parts out the pan? Haha. Somethin in there was out of whack for that to happen. The truck was definately used as a hauling truck for the majority, if not all of it's life. But even so... That's what these things are made for.,.

Wonder if he had anykind of warning from gauges or check engine light?

sounds like a stuck injector. Torched one hole until it broke a rod or the piston and shot it through the oil pan. Common rails are a little more finiky about fuel. You should be careful to run good fuel through them and keep your fuel filters changed. Otherwise bad things can happen.

id beat anything on a stuck injector

yup, injector.

his oil pressure was real low i bet, having nothing but diesel fuel instead of oil, it could of been avoided if he noticed his oil pressure being super duper low.
