My 2006 2500 with 2015 miles just blew the turbo. Took it to dealer last week to check out "siren noise" and they said turbo would need replacing, on order, ok to drive. Well, 15 miles later, it sounded like a garbage can in a Cuisinart. Blowing heavy white smoke out exhaust. It has been towed to dealer. My question, can anyone tell me what I should see on their service report for "other" things that should be checked out, ie. can metal filings get into engine/fuel system etc from this failure.
Appreciate any insight!!

 

If it has blown on the compressor side you can get metal particles into the engine- epsecially between valve and seat, piston and cylinder, maybe banging against an injector etc. Usually the bigger parts will stay in the intercooler for a while- but I feel it's better to replace it if there are parts missing from the compressor side.
If it was just the oil seal you've got to be thankful it wasn't a runaway but to me it sounds that at least a compressionand blowby check is going to be needed.

Like said before, if it was the compressor side, then metal chunks have gotten into the intake tubes, intercooler, intake manifold, intake valve seats, exhaust valve seats, piston surface, possibly between the cylinder and piston causing possible scarring of the cylinder wall, possibly hit injector tips, exhaust turbine blades, catalytic converter, etc. Basically a complete rebuild is what I would be looking at to be on the safe side.

You can probably take the intake side of the turbo off, grab the shaft and see how much play you have. If you see fresh ground edges on the blades you should see the same on the housing.

 

Was your truck completely stock?

 

Completely stock. Haven't had time to change floor mats or even wash it yet!!

 

That sucks.

I hope the make you 100% whole on this..........

 

Im surprised that they let a failing turbo out the door, they should have known better then that!!

 

Sorry to hear that - wonder what caused to turbo to self-destruct?

 

Best I could tell it had a bad bearing in it, it would whine and then a slight "grind" as it would free up....then it went to ****, fast!

 

Do you think you might have shut the engine down when it was still pretty hot?

Like pulling into a fuel station off of the highway, especially if towing or at high speed?

Wondering if the oil coked up in the turbo bearing?

 

Is it possible to have this occur at such low mileage? He couldn't really have that many run cycles at 2000 miles that this could occur, could he?

 

Engine was run all of 1 1/2 minutes before turbo crapped. Figured it was bearing, dealer said same, said ok to drive, which I was a bit leery about. Only put 76 easy, local miles on it after it was at dealer before it took a dump.
They are supposed to work on it tomorrow, I plan to be there in afternoon to see exactly what went bad and how chewed up anything was. Just hope no pieces went too far. Had to put the trusty 98 2500 back in service!!

 

I don't know if this had anything to do with it, but the manual tells you too make sure you give the turbo time to cool down (idle) before shutting the engine off. Cool down time varies depending on how you were just driving it. The danger is the potential heat transferrence into the turbo shaft bearings, coming from ther exhaust side. Do you know if you typically gave the yurbo time to cool down before shutting off the engine? Just a thought, really strange! Of course, could have been a defective bearing from the factory as well!

 

GAUGES!

I doubt cool down time caused this failure, but over time shutting it down hot is VERY bad for the bearings. The oil is at a boiling point as it passes the turbo, letting fresh (cooler) oil make it's way to a cooler charger stops this possible coking from occurring.

Plan on getting some gauges installed, it's better to quit the guessing game early and be better informed as to what your engine is doing.
