DOCTOR OF DIESEL MECHANICS ! MAN THIS GUY IS GOOD !

Just a fore warning from a freightliner mechanic in maryland when you start getting the gen 5 motors in with dropped exhaust bridges do yourself a favor and just drop the pan and check the wrist pin on that cylinder seems to be building to much pressure in that cylinder and blowing bushings/ bearings in wrist pin

I’m a 35 year Detroit tech and I approve this message. I’ve seen this multiple times. The problem is that warranty won’t pay to drop the pan and inspect for this. after the adjustment screws are replaced and you still hear popping out the intake then you check for spun cam lobes because the lobes are pressed onto the shaft the increased pressure due to the exhaust valves being closed all the time they can spin. But when I’ve seen this happen the wrist pin bushing will come apart and crack the liner and let coolant into the oil. Detroit ruined the DD engine with the gen 5. They are going to put them out of business. These changes are all due to the new EPA regulations. I’m all for clean air but enough is enough.

Great mechanic, you really know your craft. When I need work I’ll be coming to see you guys.

Well done Adam....very informative...

Dude knows his stuff.

Very.helpful. these are the checks im looking into rt now but yours goes more in depth. Thanks much

Thank you Adam. Good job. Some people would think this is a bad design for a valve failure with just over 400k miles. They have to remember, it's not just the miles, it's also the added hours of running idle. Have a blessed and safe week to you and your family. Happy Thanksgiving.

You're Awesome, nice video, explaining very Professionaly. Thank you

This video really helped me a lot

Very good information

Thanks for the info brother

I wonder if he got carbon build up from a leaking EGR cooler. That would cause a cold intake valve and allow contaminants from the coolant to build on the backside of the intake valve.

You guys are awesome

Awsome again ace mechanic 😇😁

That was awesome!

For sure stopping by

Great stuff brother 👍🏼

Well Done! I really would like to come to your shop!

Adam, I apologize for so many questions. What service information do you use? Mitchell? If so, how good are the wiring diagrams? Do they have good identification for location of components like modules, connectors, and grounds? How good are the wiring diagrams for the network (J1939 CAN Bus)?

Great Video Adam, can you share an estimate on this trouble shooting process?

Boy this guy is very knowledgeable. I wonder if I can afford taking my truck for repairs at their shop. I hope they are not too expensive.

Idk about this for sure but it seems to me it seems these newer trucks are only designed to last out IRS depreciation time frames without major issues. Not the million plus miles the older trucks were. I'm seeing early corrosion issues for certain 2 years in.

In case you have damages, wear, corrosion on the firedeck of the head. It is possible to rework the head by 0.2 mm. You have to reset the gearlash by loosening the boots on the topmost gear spindle on the block. The gearlash can be adjusted by rotating this spindle.

Hlo sir your videos are very helpful to me thanks for that will you please tell me which computer i should buy for diagnos

Great job. I have to ask. How much that job cost and how long a driver will have to wait from check in to ready to drive again. Thank you

Hope you answer me this cause I’m curious couldn’t you just grind the valve and re-seat it instead of recommending an entire new head for one valve that’s not properly closing???

My truck been blowing smoke up hills and loss of power. hours earlier it was making a loud noise whenever I accelerated and the jake brake sounded similar

Assuming the customer is skeptical, could a leak down test be performed before pulling the head? Would it show a difference or just a waste of labor time?

If you plan to purchase a DD15 auto with a 500k to 700k what would you look at before purchasing? And after purchase what is you recomation?

As always I've learned something new today, thanks Adam, by the way i have a cat C15 accert 2005 you guys work on those right?

This is interesting, What would be the best maintenance to have good valve seating? I have seen a few DD15 have low compression on cylinder 6 from engine with 300k miles to engines with 700k? Have you found what is the root issue of why cylinder 6 have these issue? ( poor lubrication, poor fuel flow to this cylinder,etc)

@bryanlowery2456

I'm pretty sure he stated that is was that the valves weren't seating (sealed) and that's why it had low compression

Hey Adam I have a question that no one has been able to solve yet. A few months back the number one injector went bad on my dd15. I had it replaced and ever since whenever I'm under a heavy load the engine will cough a couple of times when going back to throttle when coming off a hill. The problem is sporadic. And as long as I crowd into the throttle it doesn't happen , it's only when easing back into the throttle. And it's only when I'm loaded heavy 35000 Plus. The scenario goes something like this, I pull a steep grade reach the top and cruise back down off throttle. When the terrain flattens out and I ease back into the throttle to maintain speed the truck shakes violently for a couple seconds then Smooths out but if I stomp down on the throttle and then back off it doesn't do it. I've asked several mechanics and other drivers with dd15 and no one seems to have had this issue.

I’ve plugged it into computer and got SPN1327 as the lookup code indicating cylinder # 5 misfire. Is it my fuel injector? Does it have to be replaced or can it be cleaned? I also think it could be due to a leak coming out of my high pressure fuel line? I have pictures if anyone could tell me what this is. Thanks
