Causes Of Turbo Failure 

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!

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.

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!

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.

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

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

Thank You! Knowledge is so critical.

Very good analysis and explanation.

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

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

Excellent, Thank you!

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.

very informative, thanks

Great video Nick

Very informative

amazing sort of forensic investigation into turbos

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.

best explanation of turbo's most common problems .

This is very informative

Yep go into detail on all dmax turbos

Great video

Thanks

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!

Thank you. Good information, Now I lo know why my Turbo failed, and I thought it was just a bad remand from Freightliner

Thank you, I have your stealth 64.

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

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)

great video of cause of failure of turbo with proper root cause explanation. #HATSOFF Many things has cleared about that. Thank you!

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?

Hey Nick I blew my stock turbo to bits on my LB7 should I tear down my motor to inspect for any turbine shavings or bits of turbo wheel I ordered a stealth 64G2 turbo and I’m worried if I put the truck back together with new turbo and have engine failure in the future I need my truck back on the road as soon as possible !!! Awesome video by the way !

Could a new turbo, just fitted, leak oil on the compressor side if the pre-turbine exhaust flange was leaking badly?

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.

I just replaced my old TF035 turbo with an aftermarket replica... was running okay but after making some tuning adjustments, I'd forgotten to tighten the intercooler hose clamp before taking it for a test spin. Very quickly into the drive the intercooler hose popped off while in boost of a little over 10 PSI. After putting the hose back on and tightening... it runs about the same but now has a high-pitched whining sound whenever turbo is actively spooling or maintaining. Could you give me an idea of what exactly happened within the turbo and if it's easily repairable? Guessing something to do with overspeed as a result of the hose popping off at a higher pressure?

Yeah I want to hear the differences between each Duramax engine’s turbo

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. Jason from the UK 🇬🇧.

I have a 2003 LB7. I bought a built engine, a WCFAB Stock/S475 through you, and a DT-750. I have fixed 4 boost leaks. I can build 25 psi at the Pipe that goes to the intercooler but I can’t build any pressure at the Valley turbo’s mouthpiece. If I put my ear on the Turbo mouthpiece there is a bubbling or gurgling sound. If I have a bad bearing or bad thrust bearing would it leak boost test pressure into the oil or coolant system? My boost leaks were the shop forgot the 2nd boost sensor port, the S475 compressor plate, the MAF sensor port, the bottom bolt of the Valley turbo’s compressor plate. I will probably get a 64mm Valley to match up better with the S475. I have smoke at 1/2 throttle to WOT. Do you sell a cap to cap off the IHI’s turbo’s compressor outlet?

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.

Nick great video I talked to Cris about a month ago my 2013 dura max and it’s issue my hoping that I can drive to your clubhouse and let you guys get into my engine I live in a desert for techs East Lansing Mi we just don’t have shops like yours here maybe I will call and talk with Cris and get something on your schedule and can’t thank you enough for all your support videos🏋️‍♀️🤺🤩🤗

At some point Cummins was buying turbines for their engines that were manufactured in India, they were failing left and right.

I have a question for you I don’t have a truck I’ve got a 21 Infiniti Q 60 TwinTurbo and I am running a boost controller the other day. I noticed that one turbo was spinning faster than the other. I checked for boost leaks can’t find anything when I pull the air filters out which are k@n I noticed they were a little bit dirty so I pulled them out and I put the factory ones back in while I clean the other filters so I started it up and both turbos are reading the same rotation, speed, can a dirty filter, cause that thank you for your time Brian

What effects can a butterfly exhaust brake have on the turbo?

26308 hours on the motor and the crank broke before the turbo went. Mobil 15w-40 with one quart of Lucas every 4500 miles

My 2012 f550 is on its 3rd ric flair. 100k kms

I checked my oil level on cold it was max. But on hot as the manufacturer GM said (operating temp) wait 5 minutes and check level, i did it was at minimum i added some. 1/3 of a Litre. So i was driving and there is now white smoke coming out the turbo i suspect. I wish i can attach a video. But yeah i was giving it a little gas, parked left in idle pop the hood, and found white smoke coming out of I'm suspecting the turbo. Is this also possible with a dirty air filter? I'm gonna check and.change my air filter today, I would do an oil change as well, but can't afford it atm. When we took out the turbo it had some side to side play(i had to use two fingers to move it, people said this is ok), but not all round, all the tails are intact. But the middle screw that's holding the intake turbo fan, is like slighty chipped. Is it out of balance now? Could this also be a vacuum issue (positive crankshaft pressure?) The sound of the turbo is normal, no whining, and the blow off does the normal Pshh sound. Opel Insignia 2009 2.0T Petrol Or Buick Regal 2009 in the US. I'm not from the States i live in Serbia, Hope to hear from you.

What causes early electronic wastegate failures?

Will excessive engine idling damage turbo or dpf on a lml? Thanks!

Hi sorry have a question my car hasn't been boosting like before turbo has more than 176k on it can it be that it's worn out??I also hear a whistle noise while idling that goes away kind of like the turbine stopping from spinning.

Does not getting an overhead play into a turbo being blown or going out?

The propeller on the intake side is not supposed to have play in it ? truck has no codes but it has a rattle when the turbo builds boost only under a decent amount of boost

How much does tuning affect the turbo surging

Why would my lmm flutter at 26 psi boost on a mini max tuner? My other lmm on efi live max effort doesn’t flutter at 38 psi BUT my thrust is done son lol new rds 64mm with a 9 blade on the way

Mine just start wiseling like a siren. Really anoying. Start at 1100 to 3000 rpm.

would it be reasonable to have an issue that isn’t going to need a full turbo replacement? Went to the dealer and they quoted $6k for a whole new turbo charger but they didn’t run any testing other than obd reader…

Why do i feel like hes talking to me like im stupid, or like its common knowledge to know the ins and outs of a turbo system? Just a feeligb
