DD15 with bad compression, white smoke, can we save it with a valve adjustment 

This guy is the best diesel tech on RU-vid. A technician, who has a software, will understand the importance of your work, thank you very much.

It is amazing that a compression test can be done without the physical hooking up of equipment to the fuel injector hole.

What I see in this video. 1. Valve train looks very clean 2. Inside of cab is clean 3. 800,000 + miles and driver takes good care and maintenance of his truck.

Chavo my man! Ine day i bring you a big meal appreciated all the hard work you do

I’m loving these videos!!! Thank you for sharing your knowledge!!!

Muchas gracias por todo. Tengo detroit dd15 lleno tamque de diesel 100 gallones y solo me da 420 millas cuando lo lleno se llena con 85 gallones cuando se tiene q llenar con 70 gallones por las 420 millas buenos esperando rinda 6 millas por gallones. Tiene filtros d dpf nuevo sensores nuevo filtros de diesel nuevos ahora todo esto lo e repetido estudiamdo las millas por gallon durante 6 semanas ya el dia de ayer lo lleve al deler a hacer ajustar las balbulas y estaban abiertas . Pregunta cuando las balbulas estan falta de ajuste puede causar consumo de diesel? El truck tiene 679273 millas o depronte me podria dar otra recomendacion q cause el consumo de diesel

Nice video Pls make video what kind of test ls we need to make before buy a truck

Lo mismo hace mi troke y tambien es un freightliner Cascadia 2015 DD15 white smoke when weather is very cold y corro poquito y se le quita, corriendo no hecha humo, solo cuendo prendo motor y corro despacito tambien huele feo y cala en los ojos. Compusieron ese troke? Y si asi fue, cual era el problema?

Nice content. Can we get your shop location. Maybe will get a chance to drive by

My guess is that he has excessive valve recession on at least cylinders 5 and 6 and he also needs a quantity control valve due to the saw tooth pattern on rail pressure.

Hello master. What the reason smoke 💨 come out from crankcase breather. Only it’s coming out from crankcase breather ? Engine DD15 2016 Thanks an advance

I recently had a valve adjustment on my DD15 @ about 700k with none of the issues this truck had in the video but recommended as routine maintenance to my understanding a compression test determines the valve adjustment and on which cylinder and the idea is for each cylinder to operate at 95% or better?

Is there any way to perform a cylinder leakdown test like with agas engines? This would pinpoint where the compression leakage is at?.....

My super hero did it agian !

I’m blowing white smoke and consuming oil about 3-5 gallons a week because I don’t have an apu. I have a ddec6 14L Detroit Deleted . It’s becoming hard to start and the valve job didn’t fix it. All signs point to compression and I’m not adding coolant. 1.3 mill miles . Wild guess how long before this truck doesn’t start?

Did you inspect cam while doing overhead?

Is it normal for white smoke after a delete?.because i know theres no egr or def to cool the exhaust down.

May I ask what would a delete have anything to do with the truck running like crap? If it was deleted, would you have done or diagnosed anything different? And what does zone 5 mean?

Hi I want to do this job on my truck do you have a video how to found the marks and turn engine and timing position thanks is a way to contact to you for best guiding

Have a long crank and power loss in lower gears. Any recommendations? Thankyou

I have an issue, my truck runs cools idling and when I am on a small incline idling it runs hot. Also it smoked white smoke a bit and solid engine light is on.

My 2012 DD13 is tuned and deleted and doesn’t show zone 5 on my dddl8 it stays on zone 0

Hey bro do you have a link for the software?

Any idea on my problem ? DD15 Engine doesn’t start once in a while, when idling u can hear enigene sputters, i can smell smoke! Mpg is great no shaking , doesn’t lose power, i have light nox sensor check engine light. Engine does not derate , def usage normal

Can you replace a head for me ? I was wondering how much that would cost me. I have all the bad symptoms had 2 valve adjustments this year problems keep coming back after 10-15k miles. I was also told by dealer to replace the head soon.

My cylinder 6 has 27% should I try valve adjustment?

What is your location ? I would like to get valve adjustment my truck reached 7,70,000 miles

how can i get his software for daignosing my trucks

Did the customer get a in frame done?

How much does that cost I’m having the same issue

From where the smoke was coming out

So what did you do to fix it?

I got code spn 1325 fmi 31 and it says 3rd cylinder misfire, fuel issue 25% derate, stopped at shop in Nebraska, also I have a load in my trailer, and they replaced injector than I did parked regen and truck was running well no codes on it,but while in the shop they also did compression test and told me because I had to leave and complete delivery that cylinder number 3 and 5 had bad results and should be taken care of, Tuesday December 6th I'll be back to Los Angeles so could you provide me your address where I can get my truck for further diagnostic and fixing the problem, it has 817 267 miles on it,also this morning in Utah had trouble starting the engine, it cranks short time than stopped, had to use starting fluid to keep going now don't want to shut down the truck because of that problem, have to first make delivery tomorrow morning than bring the truck to my parking.Please respond if you could help.

How much did this cost the driver?
