Does you engine sound like this it the morning? If it does, you might need to look at your valve adjustments. Detroit recommends to have your valves adjusted at 100K miles and then at every 500K miles.
I definitely do not agree with this, I recommend to have your valves looked at or have a compression test done every 100K to 150K miles as part of your regular maintenance. It is a lot less expensive to have your valves adjusted than to have your cylinder head replaced or possible engine failure because of a dropped valve that can wipe out an engine.
These newer emissions engines are not like the old school Detroit Series 60, Cummins N14 or CAT engines. I know it’s not what we want to hear but it’s the times we live in.
I have a question for you may be you know
Why dd15 has problem with 6th cylinder head intake valve 90 percent in cases? Why they worn faster than others?👆
Truckers don’t spend money for adjustments, expect breakdowns
@@JoseMartinez-jl1mk sad but true. Those break downs get expensive
Manufacturer suggests VALVE LASH ADJUSTMENT**
ADJUST AT 100,000, AT 500,000 AND THEN EVERY 500,000 THEREAFTER.
Those used truck only did the first time @ big transportation company, then sold to the market. Most of them don’t do this maintenance until breakdown.
They don’t know it hurts engine and one box.
In my opinion,Hard to start, bad emission smells. Those symptoms means valves lash tight,fuel can’t burn completely, it goes to one box. That is why the one box failed fast after 600,000miles for someone.
@@JoseMartinez-jl1mk truth.
My DD15 just recently hit 500,000 so I need to get this adjustment? I just happened to be in the manual and saw 500,000. What does a shop usually charge for this? Thank you.
Valve adjustment typically costs $450 on up.
I had a customer just come in our shop for a valve adjustment. His truck just reached 501K miles.
There were a few intake valves that were tight, so we proceeded to adjust all the valves regardless. This way the adjustment is done across the board.
@@CarlosDieselElectric Thank you. I will get it done.
Best on youtube

@@CarlosDieselElectric ruclips.net/user/shortshVMRLZVtlnU?si=eTlIG_ut_5mVU7ub not many people can find problem VOLVO D13 2018 and UP only at regen progress you can see cracks
4:13 Don't need a laptop to tell ya it's got a dead hole. Just listen to the cadence cranking over. That skipped beat is a cylinder with zero compression.
Which cylinder it is is irrelevant. One ain't squeezing right adjust them all. If it still aint' squeezing right, head's coming off for a valve job do all six holes.
@@TestECull I agree. Heads going to have come off either way. Customer is trying to buy some time before the engine gets repaired correctly or a newer truck. California has some strange rules when it comes to 2011-2013 trucks
@@CarlosDieselElectric I'd be surprised if it was running on more than 2 or 3 cylinders truth be told. Diesels live and die by compression and with one completely dead hole and two showing only 20-25% what they should have it's a miracle that thing started at all.
Makes ya wonder why they're eating valves, though. This wasn't an issue with the Series 60 4-cycles or the 2-strokes before that. 'Course I have no doubt in my mind Commiefornia would have a siezure if you tried to register and use a tractor with a screaming jimmy in it today......
@@TestECull once the DD13 and DD15 switched to the single line on the intake cam. I noticed the valves get out of adjustment faster if not maintained.
The dual lobe cam on the intake seems to have lasted much longer.
How much does a valve adjustment usually cost? I ask a shop near me he is telling me is 1k is this about right?
@@turbovtec5390 for a DD15 around 400-450. For a DD13 in a short nose Cascadia, slightly more because of the lack of room. A DD13 has half the motor inside the cab area.
But $1000 is way too much. Even with a new valve cover gasket which costs $75 on the high side. You still are not anywhere near $1000.
Find another shop. We all need to make money but that seems excessive for a valve adjustment on a DD engine.
hey bro.. can you do a video to reprogram ECM on cummins swap engine to reprogram correct VIN
Bro...
GHG21 dd15 manual showing valve adjustment every 500k.
Not sure ghg17 but used to show 100k then every 500k after.
Funny how ghg21 engine has issue and has recall on it.
I honestly think there is an issue with the design or the recommendation when it comes to intervals and when they need to be done.
If Detroit thinks you can adjust at 100K and then at 500K miles. They are crazy. That is a big leap in between.
If all cylinders come very close to a 100% during relative compression test - do you still need to do a regular valve adjustments?
@@ofilippov probably not. But if you are concerned you can check just to be sure.
This truck Def level lights put tape there. It needs to upgrade to clean truck or out of Ca. Carb will request smog twice a year for registration.
@@JoseMartinez-jl1mk you caught that. Yeah, there are a few of those out there.
Thank you 🎉😊
You dont necessarily need a new head. Just replace valves, valve seats, and guides with a bit of machining.
@@MarcoSandoval-sj4sv true. As long as the cylinder head is good to rebuild. That will save some money.
Put a rebuilt head on get rolling, time is $$$ ... or so I've been told.
Is there a similar test on cummims insite?
@@jamal-ce5yf depends on the engine. For ISX series. Yes. It’s a cylinder performance test. Goes through all 6 cylinders and is pass or fail.
So similar yet slightly different
When is the first valve adjustment after an engine has been overhauled?
Every mechanic is different on what they want. Some want you to bring it back for the first oil change to follow up.
Then some 50K miles want to check the valves.
But if you go by Detroit recommendations. 100K miles.
@@CarlosDieselElectric thank you for your reply
Is Jpro better or OEM software better?
@@IvanRodriguez-fg7wk I personally like the OEM software. But have heard good things about JPro. They seem to have good wiring diagrams included with their software. Detroit does not. That is a separate subscription which I think is weak.
Cummins does offer diagrams and wiring with troubleshooting
OEM software is always better vs any aftermarket one.
