Why are you not using a Torq wrench?

[@bustedknucklebydieseldr3228]

When you’ve been doing this for 20 years you will know what a torque setting it just by feel. Only time I double check it is when I’m doing engine internals.

What kind of bit did you use to clean the surface of that hosing?

[@bustedknucklebydieseldr3228]

I would use a scotch scrub pad,Emory cloth , or a scrub Rolex disc. Any of those would do just fine.

Sorry question has nothing to do with video. Why are dd15 2 high pressure lines one time use only? Replaced pump seals. And now one of new lines is leaking evidenced by fuel seepage around one line

[@bustedknucklebydieseldr3228]

Haha all good man. That happens quite a bit. Good question. Due to the high pressure being used in the line and the thin material compared to injector feed lines, detryhas determined that these two lines are the weak link and will leak or blow if reused. I’m sure if they were made thicker than they would be good to reuse but there cheap enough to replace especially if you look at the alternative,, breaking down. Hope that helps.

Anytime man. As long as it’s a reputable shop they should do whatever necessary to make things right. Atleast that should be the mentality all around. Dont forget, these videos make great bdays gifts. Thanks for your support by watching and stay safe out there.

So I'm Finally receiving a Gen 5 DD15 the first week of January after ordering it 6 months ago. My current DD15 has 900k on it and I feel like it's just a matter of time before it goes. Anyways I've heard of problems with the rocker arms breaking off in the head with the gen 5 DD15. Is Detroit know about the problem and do they have a solution yet?

[@bustedknucklebydieseldr3228]

Congrats on getting you new ride. Going to be a completely different beast. You are correct there is an issue with the adjuster screws breaking apart or getting worn and causing noise.Detroit knows about this and will eventually make a material change to fix this issue but for now its just the weak link in the valve train.

Hey bro how r u? I’m facing a problem on my freightliner cascadia dd15 dOC low temperature then one mechanic figure out its a fuel doser he changed it buy still doesn’t work then he changed hydrocarbon dosing block but still problem is there it says abnormal fuel dosing? What can cause this any idea ? My truck is sitting in the same shop for 4 days He said he is priming it or something like that Let me know if u can help

[@HarpalSingh-qz9pg]

Truck is derating now with low doc temperature due to the failure of fuel dosing

[@bustedknucklebydieseldr3228]

Thanks for reaching out man. With that particular problem the hydro carbon doser block is infact a likely failure. Once that’s been replaced he should be able to see fuel press from the block to valve and see if it’s good. If it isn’t than the valve is plugged If it is good than we have an issue with a bad sensor in the aftertreatment. Also one thing that will cause this is any exh Leaks. Hope this info helps.

[@HarpalSingh-qz9pg]

@@bustedknucklebydieseldr3228 he changed 7th injector and hydrocarbon doser valve all the sensor on after treatment box are working fine the only problem is fuel doser injection status stays 0 with new injector and hydrocarbon doser Still wondering why?

[@bustedknucklebydieseldr3228]

@@HarpalSingh-qz9pg I see the problem here. If the injector status stays 0 than the regen is only getting to 800 deg f. If that’s the case than the regen isn’t happening. Running a doc u plugging routine for 10 min than stopping it, than running a regen should clear it up. Sometime it will get stuck and not dose fuel. If that doesn’t work than I would flash the acm to see if that will wake it up. I’ve had these issues before and usually one of these work
