Causes Of Turbo Failure

We've seen some of the brutal shots/videos of turbos having catastrophic failure, but why could that have happened? Nick breaks down a few direct causes in this video. Axial bearing issues, how the thrust bearing can tell a story of turbo failure, and much more in this Diesel Insights!

As someone new to the LBZ world, I really appreciate your breakdown! My buddy sent me your channel and now I have a lot of homework. thanks guys!

Great detailed video of Turbo failure with in depth engineering explanation! I do appreciate your videos and how to understand the system of diagnosis down to the component level diagnosis to tell the story. Thanks for sharing your knowledge and experience!

How about a video about the common weaknesses/failures of each model yr turbo and what CPS has done with the stealth line of turbos to address these weaknesses

[lawnboy]

Thanks Nick! As always love the videos and all the information. I wouldn't mind a video on the common failure points on specific turbos. I have an 18 L5p. Thanks again.

amazing sort of forensic investigation into turbos

Most turbocharged engines today are running on 0 wt 20 oil. Will that contrute to damage and failure??

best explanation of turbo's most common problems .

As a new Lm2 owner - first time diesel owner, I'm learning a lot . Thanks and I'll be watching.

I have LB7 with leaking injectors - already spent $10k trying to get it fixed, but still leaking. I now change oil at 3k because oil is getting diluted, been doing that for 30k miles. Guess what? Power is continually decreasing. I think you nailed my problem with your statements of poor oil. This video helps me to direct my attention. Thank you!

Thanks Nick. Bought the Stealth 64 for my LB build.

Excellent in depth of the inner workings of our turbos. I watch a lot of Dmax videos and enjoy these the most. Very well presented so anyone can understand.. technically speaking.

I remember working in the field and I pulled the killed the tractor at the end of the day and my dad chewed me out. At 13 I learned that you have to cool the turbo down for awhile. Before you shut it off. I do that with my pickup. As a precaution just gives me a peace of mind.

From not knowing a thing about a lly my wife inherited. I've learned so much from you. I don't want to work on duramax for fun, I want to do this for living.

Hi Nick, can the DEF system cause turbocharger failure on a 2016 Hino 268 box truck with 274K miles? My check engine light came on and my truck started struggling to go uphill and after stoplights. A mobile mechanic suggested turbo replacement and deletion of the DEF system. What are your thoughts?

Ive a 1995 volvo 940 lpt and the turbo just isnt boosting. I noticed after i installed a gauge.
Since then i bought an adjustable wastegate (Ive tightened it way too much for a functioning turbo, still no boost..)
Checked the dump valve, it seemed perfectly fine?
Checked inside by taking off the large hose, spins fine, doesnt rattle or have any massive gaps.

I really dont know what to do anymore, i also tried driving without the wastegate hose connected, still no boost.

Great Great vid. ❤❤❤
I actually would like to know your opinion on why ford's 3.5l eco boost Garrett turbos fail like they do

Please help I own a rv 7.2 litre catapliar engine, I don't think it's the turbo but I'm no expert.
What's happening is 1600 rpm to apx 2100 rpm I'm getting a whistling noise.
Noticed when the engine gets a little hotter the whistling is still there but at a lower volume as if it's doing away.

Is this turbo related? I cannot seam to find the issue.

Please advise on any of your thoughts and thanks you.

One other major thing, is to make sure that an engine that's been loaded, to cool before shut down. If the turbine volute is still hotter than the break-down temperature of the oil, the oil can 'coke', and that can cause a bearing failure. The lower the break-down temperature of the oil, the more important a cool down period before shut down. (idle the engine a few minutes before shutting off)

I no this is a duramax channel an I respect all brands of trucks, I have a 06 6.0 powerstroke bought it 7 months ago it’s a lariat with 96k on it so dealership replaced the turbocharger after I test drive it was making a loud high pitch sound like the wheel an hosing were not getting along best way I can describe it, while they had it 2 injectors where not happy so they replaced all 8 oem injectors an new injector wiring an it’s definitely back to how it should be an no issues my question is based on this video are all turbochargers the same as in thrust bearings an balanced an the same failures? Since owning it I did new hot an cold side piping s&b intake crankcase reroute sinister diesel blue spring kit aluminum 3 core radiator 4in straight pipe to a axle dump an a cts2 edge insight monitor fresh oil change if the time ever comes what’s a daily driving friendly turbocharger and do I need to do injectors if I do a different turbocharger? Thanks for the awesome videos I’ve learned a lot from this video an would love to learn about other ways the turbocharger can fail, thanks nick.

Very informative great video, i like to hear the exact details.
