Turbo charge killed our engine

The roadside guy should have, at the very least, removed the CAC and taken the CAC back to his shop and washed/flushed it out. Any time I do a blown turbo job, I prefer to send it out to a reputable rad shop for cleaning and testing. If its not possible, drain, degrease, flush and reinstall. Better than nothing.

 

Okay so I have admitted that it is possible. And yet you ask how do I know because I am a specialist call most destructive engineering because I was driving along I-80 in Ohio coming from Pennsylvania hauling a load of paper and all of a sudden I yes there was a bunch of smoke came out the exhaust and I just heard a funny puff puff. So I got out after I stopped and looked over the truck I did not see anything out of ordinary so I got back in the truck and started along. I went down the road another 10 miles and that old FLD with the series 60 12.7 decided to make a big old woooof and this time I smelled smoke in the cab like burnt oil, I did not even turn the truck off I just let it sit there and idle well I got under the hood look over things. So then I found oil spitting out of a turbo and was trying to figure out where it came from and the moment later a fire truck pulls up and tells me to shut the truck off. Next I got towed to a shop to repair it they said that I was going to need a new Turbo so it was ordered and I waited a day or two. When we got back to the truck when I got back to it turns out they told me that when the second time there was the big poof is when the turbine from the turbo blew chunks and stuck into the back of the trailer after with through the muffler and exhaust pipe. So when somebody tells me a 12.7 Detroit series 60 is going to run away, almost always I don't necessarily believe it.

I posted a thread in here years ago on why the Detroit 12.7 ran off that my buddy owned. They replaced the turbo because the seals had gone out, and the mechanic didn’t clean the CAC. The truck cranked, idled and when they gave it some throttle it ran off, hitting over 3500 rpm. Blew the head gasket, and messed up several things. It was a DDEC 3 500.

 

It depends which side of the turbo goes. In the middle (where the oil lines connect) are the bearings/bushings. If the oil seal to the inlet side goes, it can suck oil into the intake of the engine. If the exhaust side seal goes (turbine end), it blows oil out into the exhaust. No chance of a runaway engine if the exhaust side fails but if you have an aftertreatment module, kiss it goodbye.

 

Module?

 

Yeah, many repair places used a cartridge to repair the turbo, it has the seals and bearings all in one unit and you put the rotor and impeller on, check it and put it back together.

I've got maybe 10 cartridges on the shelf for some of the older trucks and a few turbos ready to go just in case. If the truck is within a couple hundred miles of either here or the office, we have a guy go out and fix the truck.

 

The DPF/DOC package is refered to as the aftertreatment module. Pump oil into that and its pretty much toast. Cummins here won't even touch a DPF that has oil in it.

 

Dpf is easy repair.

 

Not cheap to replace though if its oil damaged.
