2020 GMC Denali 3.0L Duramax P0016 Code. Oscilloscope Test Proves Timing Was Off
A 2020 GMC Denali 3.0L Duramax came into my shop with a check engine light. Code was P0016 for crankshaft and camshaft correlation. Vehicle had 120,000 miles and they just bought the vehicle from the dealership. From my research for this engine with this code I was not able to really find anything regarding diagnostic. The only way to see if timing was out was to go into the engine and physically look at it. So I did a oscilloscope test before tearing down the engine to get a known bad waveform. At the end of the video I show the good waveform and explain the difference. Knowing the good waveform will help diagnosing this code again in the future for this engine. Hopefully you found this information useful and are able to use this in your own diagnostic procedure of this code for this truck.
Hope You Enjoy and Godspeed ✌️

where is your shop
Did you replace the seal on the timing cover for the oil pump selonoid if so what’s the easiest way to do it without the special seal installer my truck has 66k miles 2017 the dealership did the timing cover leak job messed up 2 got it right the 3rd time now my oil pump selonoid is messed up gotta replace the oil pump by myself cuz them or the warranty company won’t do anything about it 4600 miles after the had the timing cover off 3 times now it randomly looses oil pressure but still actually has oil pressure throws a po6DA code oil pressure selonoid check failed so gotta replace the whole thing myself any advice from anyone would be much appreciated starting this Friday night Aug 30th
Yeah I replaced the oil pump solenoid seal. I usually lube it up with some sil-glyde or you can use oil. I sometimes can work it in by hand or use a little hammer to work it in. But make sure to double check the circuit because I believe that P06DA code is a circuit code. That wire runs along the front of the engine behind the belt and sometime techs won’t secure it properly and will damage that harness that controls the solenoid. Either way I hope you get it fixed!
Awesome job man! I wonder how many of these out there have chain stretch. My 2020 LM2 is just about to hit 30k mi on it. I don't drive much. Got rear-ended at the start of the plague and had to get a new truck. Post-plague is still mostly WFH except long trips for those corporate "team building" exercises. It's a dull life these days, but guys like you are still doing actual work. 👨🔧
I appreciate it! But yeah that is a good question. This is my first time doing this job and don’t work on too many LM2 to know if this is a common issue or not. My guess is probably how the truck is being used. If it being used to haul heavy stuff that is definitely going to put more stress on the chain unlike the other heavy duty trucks that are gear driven. But I have also seen a lot of other GM vehicles having stretch chain issues 🤷🏻♂️ so maybe GM don’t make good chains for their vehicles.
You had me excited until about halfway through the first video when you started doing the timing cover, then I realized there is no way I can do this at my house. It went downhill from there. I want to get a car with a simple motor, haha. Question. I have a 2017 explorer 2.3l ecoboost that has a head gasket leak, but its leaking very little water and the engine hasn't overheated. How much does it cost to just replace a head gasket, without milling the head or getting a new engine block? If its insanely expensive, im honestly debating on just using some head gasket repair sealer and just taking a chance, if it seizes my motor, oh well.
Yeah they don’t make simple motors no more unfortunately 😂. I believe this head gasket job on a 2.3L is about 20 hours. Depending on the labor rate it’s going to be around $3,000 just for labor. I think I saw ChrisFix did a video about using head gasket leak fix. That might be a good watch for you to determine if you want to go that route.
@@godspeedautoshop i had just watched it today before you commented. I think I'll get a tester kit and make sure its coolant getting in the head and then do it. Thanks for the reply.
@@godspeedautoshop i mean it too, really, thanks for the reply, you answering the hours and approximate cost helped. I appreciate it. :)
When priming, Is there a specific reason to go through disconnecting the fuel pump rather than just using the "clear flood" function built into it by holding the accelerator to the floor (keeping the injectors from pulsing)?
Honestly I know about the flood mode, but never even thought about using to prime the phasers 🤯. I think you are right in it would be easier to do flood mode after doing the repair. I’m definitely going to start doing that from now on! Appreciate your comment
Uhh forgive me but Ive already seen this done without taking the whole thing apart. I’m sorry but I don’t like this video.
It’s ok you are forgiven
Hiw do you do it without ripping the entire dash apart. I have to replace this
Hello sir. Thank you for this video. I have a question. Is this condition that happens to the engine due to high pressure on the engine or is it considered in many car manufacturing companies as a (manufacturing defect). Knowing that the car is still new as we see in this video of the 2.3 Ford engine.. Is it possible for you to explain to us the reasons. Thank you
Yeah absolutely good question! The head-gasket has a big job in keeping the engine running properly. It keeps the oil and coolant separated and seals the head and engine to have a combustion chamber. Head-gasket is always experiencing pressure from oil, coolant, and the combustion while engine is running. Now with these Ecoboost engines (1.5L, 2.0L, 2.3L) they have a turbo which forces more air into the combustion chamber. This of course will dramatically increase the combustion chamber pressure and more pressure on the head-gasket. Now it’s not the turbo neither is it really the head-gasket fault they are just part of the equation. The point of failure is really the way the engineers design these short blocks. I showed in the video that there are slits in between the cylinders for coolant to pass through. So the cross section of the head-gasket between the cylinders is very small. So after a while that specific part of the head-gasket between the cylinders, which is the weakest, will leak coolant into the cylinders. So a couple of years ago when most of these vehicles with these engines were still under warranty, the fix would be replacing the short block because they re-designed the block to remove those slits and drilled holes to allow coolant to pass through.
@@godspeedautoshop For Ford. Does this problem occur in all engines that are designed with a turbo system? And how is it for other engines 2.7 - 3.5. And does this problem also occur in engines that are not equipped with a turbo system?. ... Thank you
@Benbenford I really only seen this problem on the 4 turbo cylinders engines. The 2.7L V6 don’t have the slits, and 3.5L have the slits, but they don’t really have coolant intrusion in the cylinders problem. They got their own problems lol.
Hi there, when you moved the turbo out the way, the service manual says to discard both turbocharger oil return tube and turbocharger oil supply tube along with the coolant supply tube, and the turbocharger oil supply filter, do you have to replace these tubes and filter even if you're only moving the turbo out the way? Also, you mentioned that discharged the AC system, is there a reason you did that? unless I'm missing it, I don't see anywhere in the service manual for the head removal procedure that any AC part has to be removed except the removing the compressor belt. Here is the list of parts I have out the service manual that it mentions to inspect or discard only when replacing the head gasket, the majority on the list are discard and replace only: EJ7Z-6051-B - GASKET - CYLINDER HEAD, CONFIRM CYLINDER BLOCK TYPE BEFORE ORDERING. SAW CUT OR CROSS DRILLED, FOR SAW CUT BLOCK ONLY, SAW CUT BLOCKS WILL HAVE A SLOT BETWEEN EACH CYLINDER ON THE TOP SURFACE OF THE BLOCK turbocharger coolant supply tube turbocharger coolant tube O-ring seal catalytic converter nuts catalytic converter flange gaskets catalytic converter gasket (turbo to cat)EJ7Z-6L612-A turbocharger oil return tube FR3Z-6L092-C turbocharger oil supply tube GB5Z-6K679-C turbocharger oil supply filter BB5Z-6C683-A turbocharger gasket EJ7Z-9448-B intake manifold gaskets CJ5Z-9439-A high-pressure fuel tube high-pressure fuel pump bolts high-pressure fuel pump O-ring seal high-pressure fuel pump drive unit gasket valve cover gaske t BB5Z-6584-A Motorcraft® High Performance Engine RTV Silicone / TA-357 (WSE-M4G323-A6) crankshaft front seal CM5Z-6700-E crankshaft pulley bolt 1S7Z-6A340-AA Motorcraft® Silicone Gasket and Sealant / TA-30 (WSE-M4G323-A4) cylinder head bolts
For the turbo lines it depends how easy they come out in order to move the turbo to the side. (In most cases the lines always get damaged/bent from removing them.) As for as the A/C system I decided to evacuate the Freon to remove the A/C line above the front cover. So when going back together it is a little smoother going back in with the RTV seal. Defiantly not a must just made that part a little easier.
What do you do when your strip the vct bolt
i have welded a nut to the bolt ,heat conduct through the bolt. intake left side was a sucker to get off, the cam tool even spread out
these videos are fantastic! I hope you get lots more subs. Extremely helpful!
Appreciate it my friend!
Awesome vids with great detail! About to tear into my 2.3 in my RS which the headgasket failed on for the 2nd time. It's now out of warranty of course but just over 55k miles. Keep up the great work!
this is an incredibly well put together video. I am astonished it does not have more viewership and engagement. Wish there was a part 3 for the rebuild.
I appreciate it! There is indeed a part 3 of putting everything back together.
Hi Im about to replace the door lock actuator on my 98 LS400. Your other video was really helpful when I was replacing the fronts. I just wanted to ask how does the door handle connect with the door lock actuator to open the latch? on the front it was connected by a rod but I didnt see that anywhere here.
Glad it was helpful! To answer your question there is a little lever that is part of the exterior door handle that will disengage the latch. At 16:30 you will be able to see that little lever on the handle top middle of the screen.
Hello, I saw your video and it caught my attention. I have a 2018 Ford F150 Lariat 3.5L and I am having problems with that noise and the transmission. What part of the country are you!! I would like to solve those problems.
Great video series, I watched all 3. Do you have to replace any bolts, hoses or gaskets other than head gasket? or can you reuse? I know that Ford sometimes says to replace some parts like bolts or gaskets in their service manuals
Yeah there are a couple things that should be replaced when doing a job like this, like the exhaust gaskets, intake gaskets, crank seal, valve cover gasket, and certain o-rings.
@@godspeedautoshop thanks, i have to do the same thing to my engine in my explorer, i had a cylinder 3 misfire and after everything else checked out good, i looked inside the cylinder with an endoscope and sure enough i have fluid intrusion around the gasket only in this cylinder. I have the service manual from ford, but i think your videos will be more helpful to me, thanks for posting these videos🙌
Does anyone know where I can buy the clips for the top trim piece of the door?
Great job !!! 👍
Thank you! 👍
Is it the same process for just removing the intake? (Remove turbo?)
I’m not quite understanding your question. Are you asking if you have to remove the intake to remove the turbo?
Yeah you can do that with out doing the majority of that 😂
“It should expose these nutz” very insightful 14:30
You seem to know your way around the EB motor, nice job. I see a Colorado D-Tag on your wall, are you near Denver?
Thanks I appreciate it. Good eye and yep in the Front Range of Colorado.
Thanks a lot brother you’re a legend ❤️
Any time
I'm probably overdue for a timing chain and belts so if maybe do that at the same time, what's the life on the water pump? Worth doing that while you're in there?
Kind of depends how miles are on the water pump. If I was doing this on my own vehicle I would just go ahead and replace water pump and thermostat while I am already in there. Peace of mind knowing that I don’t have to replace soon after I did timing.
How long approximately did it take you to do this with all the camera changes etc? How long normally? How long for the weekend warrior? Besides the pulley puller, cam locker and the Long Reach Harmonic Balancer, what if any other specialty tools needed?
Took me about a day in a half with recording everything. Usually can get the job done in one day if there is no hiccups. For a weekend warrior very possible to get it done in two days. Definitely would want a torque wrench.
I really like your video and music !!
Thank you!
Is there enough play in the AC lines that you could keep the condenser connected and just push it to the side or is removing those 2 lines a must?
I think removing those two lines are a must if you want to position the cooling module to the side. The A/C lines do have play, but I don’t think enough without damaging or compromising the integrity of the lines.
What tool did you use too put back that crank pulley?
It’s called a Long Reach Harmonic Balancer Installer Tool
@@godspeedautoshop thank you!
What's the name of the tool you used to slightly rotate your VCT to allow the install of the Camshaft holding tool?
It’s an 11mm impact ribe bit socket.
Why did you not use the new phasers?
I was wondering the same?
So long as they're the HL3Z-CD phaser they're the same as the ML3Z-A. The ML3Z-A is what you're thinking of with the cage over the spring. The ML3Z-A otherwise is the same part from a different supplier.
Probably Warranty job lol, they need to get them off the shelves somehow
@@BuckChoklitt Wrong! The HL3Z are the OEM parts that WILL fail. The improved parts are the ML3Z phasers with the cover and (hopefully ) failure resistant. I just got my '19 back and physically saw the two side by side, The dealer used the new Motorcraft ML3Z pieces and it was done at ~46,000 miles under Ford's TSB 23-2143 at no cost to me.
There is an updated cam phaser out that should eliminate the rattle. You replaced yours with the same defective model 😮
I made sure that the customer has all the important part numbers that I installed in the vehicle for the record keeping of their vehicle. Sometimes that is all I can do in the position that I am in. I mentioned some videos that explain the VCT failure in part 1 that I believe is very valuable. Hopefully more people will be more informed like you my friend. Thanks for the comment!
@@godspeedautoshopnice job. Sorry, from your response to the other person, did you suggest the new ones and the customer said no, or they specifically asked for those? I'm just unclear about what you meant. Are there any advantages to the older ones? Also I've seen several mentions they were getting discontinued after the new ones came out!?
Good work keep it up and don't stop ❤
Thanks, I appreciate it!
Super helpful video!! Thanks!
Glad it was helpful!
Insanely helpful, working on my 01 ls430 and I haven’t gone to it yet but I can already tell you this is 90% of the process if not the exact same. Thanks for showing all helpful details and cutting/speeding up where needed this is perfect my friend
Update, just finished taking it off, it’s basically the same just look around and you’ll find what they changed it’s pretty obvious
Cool man thanks for the update! I’m sure this would help a lot other people out wondering if it’s almost the same process for other years and makes. Glad it all worked out
Very helpful. Thank you!
No problem!
Big job. Is is eaiser to remove the radiator? Would like to do this with out messing with the a/c system or trans coolers. But with it removed- job looks hella eaiser.
Good question! I haven’t done the repair by just removing the radiator before. I know when I used to do the repair from the top removing the cooling fans gives you more room especially removing turbo pipes. But if you asking if you can remove the front clip without touching the A/C system or trans cooler lines. You might be able too. You can reposition the trans cooler out the way towards the bottom. Then once removed the front clip you can maybe swing the condenser like a door to the left to give you more room.
@godspeedautoshop I should have stated is the job easier to do with removal of the front clip vs not. Thanks for the information.
Oh yeah a lot easier with it removed in my opinion. Once I learned it to do it this way I never done it any other way.
@@EcoBelkin there's another tech who seems to remove the whole body when doing this job, looks like crazy overkill. I like this, sitting in the engine. 🙂
@supastyles1 yeah- that's how I've seen it done- cab removal. Not sure that's doable with an expedition...
Great video. Is the rattling noise just a nuisance, or does it indicate a future failure? I have a 2023 F150 with the 3.5 EcoBoost. I did my first oil change at 4000 miles and plan to do it around every 4000. Is there anything else you recommend to keep that engine running solid?
Yeah at this time it just mostly a noise concern. And as far as maintaining the 3.5L consistent oil changes goes a long way. 4000 miles interval is perfect and a lot better than the manufacture's interval which is 7,500-10,000 miles in my personal opinion. And maintain the other fluids as well like the coolant, transmission fluid, differential fluid, just to overall keep the vehicle in good shape. Thanks for the comment!
You have a 2023, they updated the phasers (not used here). You have a slim chance that yours will fail.
You must need to be incredibly experienced to put that all back together.
It might look daunting, but luckily they give you workshop manuals just in case you forget.
Thanks a lot bro!
No problem!
Really well done and explained 👏 Thanks
Glad I can help out!
Would it be the same on the ls 430
Honestly I’m really not sure for the ls430. But from taking a look and comparing the ls400 and ls430 rear bumper it looks very similar where it mounts to the rear quarter panel. So the procedure might be the same to remove it, but it might have some more fastener locations or in different places. Sorry I couldn’t be more of a help, but hopefully your able to remove it.
@@godspeedautoshop thanx anyway
No problem
Great video and informative! You deserve more subs!!!
I appreciate that!
Thanks soooo much for this. My exterior door handle linkage came loose (white clip broke). I have replacement clip but haven't been able to put the clip back in place. Thanks to you, now I know I need to pull the interior trim and remove the window and guides to get easy access to the handle. Somehow, many years ago, I was able to replace a cracked door handle without taking out the window. I just remember it was a very long and frustrating job. Also, I don't know how you manage to pull the main door panel off the door intact. Every time I do that, some of the plastic mounts glued to the door just come right off, or they crack apart and I have to epoxy them back on.
I’m glad it was helpful man and was able to provide a visual! Yeah I think it might be possible without taking the window out, but like you said it can be frustrating. I like taking the window out just so it’s a lot easier. And those plastic clips those are always a hit or miss with them staying intact, but good thing you were able to fix them up. Godspeed ✌️

Hey man good job on handling that one I have a question as an future apprentice what the work would be i hear that you need all the patience
Thanks man! As for your question it really depends where your apprenticeship will be, - like if it’s at a dealership than your going be more focused on a couple of makes of vehicles and working on little more newer stuff, and R&R (Remove&Replace) - Independent/ Specialty shops are going are going to be a little bit different type of work. But I guess a piece of advice no matter what area you go in is to - absorb all the knowledge that is being taught to you -ask a lot of questions -focus on doing it right way - and yes patience…your patience will be tested a lot
