I've been following your whole "DOD" system to stop. But you really do a masterful job. Your excellent educator. And your patient !

Thanks for your videos and detailed instruction on this problem. Thanks to you, I was able to use your tool to free up my lifter, modify the VLOM, and send off my PCM for reprograming just as you instructed, and I'm happy to report the truck is now working GREAT! I will say that when I first started the truck back up after putting the engine back together, there was a soft tick. I remember you saying that sometimes the lifters will fail again but I figured that if I just let the truck run for a bit, the oil pressure would build up and the lifter would free up...and it did. Purring like a cat now! If anyone thinks they can't do this, you're wrong. I'm not a mechanic, more of a handy man, but by following the instructions I was able to pull this off and save hundreds or thousands of dollars. Good luck!

Nice, man and I’m glad you’re showing the details of the DOD system. I’m debating whether I want to do the DOD delete myself in a Caprice that I have and your vid’s are swaying me to do the job myself. -Chris

Thanks man!! i watched most of your videos on the dod delete.... was scared doing it... i'd only worked on my own crap sbc 350's etc.... my 2011 yukon was not something i wanted to work on, but did it to save the money, and you definitely helped!! It is running perfectly after having a clicking afm lifter that got stuck. I used TSP components, and replaced the oil pump as well...

Love the siphon trick to get coolant out of the heads! Great tip!

Great videos. I am rebuilding my LH6 that I swapped with a LQ4 inside a saab 97x. I drove it with a collapsed lifter for over a year and was actually relieved when it spun a crank bearing. I hated the dod with a passion. It collapsed when I checked my oil and it was normal and then the same day it began tapping. Checked oil and was dry. Added a quart then drained it with only 2 quarts. The motor ran so well before it collapsed but I got comfortable with believing it would never happen. The engine is super clean but pistons for dod were caked in carbon. They sound like Subarus with an exaust.

If you are going to replace certain push rods, rocker arms & lifters, you should replace all lifters, rocker arms, push rods just to be on the safe side.

I bought my 2015 Sierra and the day after getting it, it started running super rough and engine light started flashing. Used a obd2 reader and it was a misfire on cylinder 7. Thankfully it was under warranty and got it fixed but i am soon going to delete the DOD system

Great videos. I particularly like how you show a clip from a previous video when you reference to it instead of having to run back and look at it trying to find what you are talking about. But it also prompts to actually go watch it after finishing current video.

Good talking with you today. Thanks!

pay 40k + for a truck and this is the crap they sell you wow

Reverse thread drill bit and an ease out is much easier than welding to get that exhaust bolt out.

ok, I had the almost the same thing. Took my valve cover off just now and one of the rockers for cylinder #4 was not moving but was not lose as in your video but it was not moving as the engine cranked. I was just about to remove the intake and cover to try the "push rod fix" but saw this video. i tried the Seafoam in the oil routine and it also did not work (after 1 day). I took Seafoam for carburetors and stuck the straw down the #4 push rod hole and sprayed as well as down the hole where the rod sits. Then I used an 3/8th extension 8" long and hammer to softly tap the rocker above the top of the push rod. At first it bounced like I was tapping in a spring. Then it went solid and I stopped. I tried other rocker arms above the push rod just to see what it felt like. They all felt solid! did I fix it? YES IT WORKED!! Cranked it over and the rocker rocked just like all the others! Now what caused it???...dirty buildup in the lifter or a bad VLOM? This engine has 170,000 miles on it and it is a 2009 Tahoe with police package (probably a lot of idle time).

been with you since the 1st vid... glad to see your channel growing

what we do in our engine machine shop with aluminum heads, and this is only if there is material to do so, is to drill to the next size up, helicoil it and get a stronger bolt and a stronger steel insert. Don't use loctite on an exhaust manifold bolt, use anti-seize.

Not sure about the ls based engines but most engines have a antifreeze drain on the side of the block if you pull those out you end up with less than a cup of liquid left in the cooling system hence no antifreeze mess to contend with

Dietec Grease on the tips of the spark plugs will prevent the wires from sticking to the plugs.

This is the type of stuff I enjoy. Great Video.

I like the anti freeze drain trick

Great videos. I have a 07 6.0 vortec. Cylinder 7 misfiring. Pulled value cover and lifter is not working so I’m assuming collapsed lifter is the issue. Your videos have been AMAZING. Few questions. I’m debating on whether to just buy your tool, fix the lifter and possibly just tune out DOD without doing a full delete kit. So what would cause me to choose to do the full delete kit and not just release the lifter? What do I need to do to ensure the current VLOM is working correctly and won’t collapse lifters again if I don’t do the delete? If I keep current system and just tune out DOD, do I need to do the mods to the current VLOM you described in other videos? Right when the misfire occurred and I was driving it home, dash started buzzing stating engine had no oil pressure and to turn off engine immediately. I was 100 yards from the house so just got it home. That night, When the engine was cold it did not have any engine oil alarms like that tho. Is that something to point me to my VLOM is having issues and I should look at a delete kit? Will be pulling off the intake in a couple days to check for the loose VLOM bolts but the front two seem tight (can’t spin with just my hand or a socket and my hand). Thanks for all the videos and help.

Thank you for the video. Might I ask the labor cost to do this job?

I wouldn't say it's a bad system. Just certain setups, the valves in the L77 and L98 hold up pretty well with the dif lifters , but yeah if you own the earlier models... DOD delete for sure.

There are so many kits out there its hard to figure out which one i need

Nice, I have one to do next week. I haven't diagnosed it 100% yet but I think a non AFM lifter roller locked up and wiped out the cam.

I’m currently doing the delete on my 5.3 only thing is my new lifters have oil guides on the sides not like front back the way the afm was when removed was I sent the wrong lifters ?

I have a 2015 Tahoe AFM/flex 114000 miles with ticking on the passenger side with "No" codes or misfires. Am I a candidate for a stuck lifter? Do you make a delete kit yet? The oil sender filter is in a different location correct?

Enjoyed the video! But would have loved to see zoomed in some. Thanks

Hello sir I swapped engines in my 2011 gmc sierra 5.3. To a 5.3 deleted jasper engine with 10,000 miles on it. I swapped out the engines and I got the computer deleted at a local shop. And now I am getting mass airflow low code. And bank 2 issues with the cat o2 sensor s. I swapped out the mass airflow sensor and it was good for a short drive after i deleted the codes. I am just looking for another option of what to do thanks Dave.

I used a easy out and the first two broke on me. One was flush and other was above deck. I got that one out with channel locks

My friend, how are you? I am happy to follow you. I ask you to answer my question. I have a Yukon GMC 5.3 May 2008. I changed the machine and installed a 2011 machine. Capacity of 5.3 was light oil. I changed the package to Denali high pressure and the pressure did not rise. The same did not change, and when it turned from 8 Cylinder to 4 cylinder works backfire and looks at code p3401 p3441 p3425 and asked the owner of the machine he told me that the machine is iron and not its size

Awesome video and great work! 👏

Got a 2012 silverado 5.3. Currently doing a dod delete. Factory gm cam and lifters. I know I need to have the dod afm disabled in the ecm. My question is, since I'm just putting in oem replacement non- dod cam and lifters, do I have to get it tuned as well? Thanks

Need a little insight , if you have time, I had a lifter on cylinder 1 start ticking, I looked over the cam through the holes for any type of cam failure , haven't found any signs as this truck did not run more that 1 seconds once the lifter started ticking, I ordered new AFM lifters, i have put them in and a new Vlom plate, my issue is i have the motor put back together, and none of the AFM cylinders are opening or closing and makes truck have multiple misfire and dies, Its like it is stuck in v 4 mode, any input will be appreciated.

I had my DOD delete on a new crate motor and ever since then NOBODY knows why I’m having exhaust problems. Should I put back factory setting? I changed cats and o2 plus fuel pump FCMS. Help please.

I'm going to do the same thing but I would much rather take the engine completely out put it on a stand replace the rear main seal on the engine and the front transmission seal on the transmission clean out the torque converter in drain. Much easier work on.. on a stand. If I ever remove the heads I always take the engine out.

Hey! Thank you for making these vids, they have helped so much! I'm in the process of tearing down my 09 sierra 5.3l (ly5) collapsed #4 and cam damage. Yeah I bought it that Way ... but there are so many choices of cams to replace the dod cam with. I want stockish drivability but dont want to lose what hp I have. How does the lm7 cam work? Or maybe an ls9? I dont want to destroy it. Just wanted to bump it a lil since I'm there. What's your thoughts?

You’re a boss. Thx for this video

Can't imagine how much this job would cost, laborwise.

@crazedperformancerepair so I'm looking at an 08 suburban. Owners said it had loss of oil pressure. They replaced oil pump. Water pump. Timing chain and the lifters on the right side of the engine. Take note it was a mechanic who did this repair. Anyway. It all started with a misfire. With that being said they said that when they run the truck the lifters get louder. I seen a video u made of a stuck valve and lifter. I happen to have a 2005 yukon with the 5.3 and that suburbans got the 5.3. Could I pull the lifters from the 05 and use them in the 08? Apparently their burb is still showing a low oil pressure warning. What would you best recommend? I'd like to drive it home. It's a state away and a good price. Also. If I wanted to. Could I possibly swap the 05 engine into the 08 body style? It'd be my first LS set up. Don't know much about them but need a 4 wheel drive. My mom's got an 08 suburban I've been driving lately due to snow. And fell in love with the quality of these trucks. I'd love to own my own burb or tahoe. T.i.a.

Was wondering I have a 07 Silverado nbs vin code M all aluminum block and heads. What kit should I get to do a dod delete, if you can can you give me part numbers on what to order? Thank you in advance

I have a 2011 Silverado that I need to delete the dod on, where is your shop located?

So I'm working on this truck and did all the diagnostics because it had a miss. Come to find out it had this pos dod motor. Found your advice which was extremely helpful. The push rod on number 6, that was the cylinder that had the miss, which led me to your videos, is now tight like it should be. This truck was sitting over the weekend opened up, could it be possible it released itself? Or should I still talk it like you show?

Great video! Thank you for making it. Getting ready to do the same on my truck. Would you recommend going with one step colder plugs?

Can the vehicle still pass admissions with a stage one camm from Texas speed and another thing why I think they fail a lot the lifters is because they don't run E85 like they should all the time

Is the process the same for a 2015 GMC gen5 5.3?

I guess if replaced all of them 'll not be issue to keep it on order clean work thanks

Question. I'm looking at buying a 07-09 era Avalanche 5.3. Assuming the truck I find has no current issues with the AFM or signs of a lifter noise.... disabling the AFM with a tune or flashpaq or something would be a logical step? Seeing your explanation of the failure certainly leads me to the conclusion that disabling it means its much less likely to crap out and is a no brainer. Its a second vehicle for me and i probably won't drive it more than 25k before I resell it. I'm a master tech so doing a full AFM delete is no big deal.. but I don't do a ton of GM.

first off thank you for sharing your trick. I have a couple questions with the time frame as far as what is the best approach first do I send in my pcm i assume I won't be able to drive my truck without it. order your kit can you tell me exactly what to ask for when I send off my pcm? I have read lots of the comments to try and get the info but I just want to make sure I don't miss anything. I have A 09 1500 collapsed lifter on # 4 assuming its intake. thank you

Thank you so much. Your channel is super helpful. What's the best method you used to adjust the rocker arm with AFM?

hello. I need your help. chevrolet Tahoe 2012 is it possible to remove the AFM system without changing the camshaft?

Hey, loved your tutorial! I just did this on a 2013 Suburban and #4 valve was bad -- the exact same one as the one in this video. I put it all back together and then disconnected the brake boost wire to keep it from going into 4cyl mode. it started right up and the issue seemed to have been resolved until I started driving it down the street and the lifter got stuck again. My question is: doesn't unplugging something like the brake boost wire keep it from going into DOD mode? I ask because if I delete the AFM and get the lifter unstuck again, will it be permanent?

If you’re in the metro Atlanta area, I disable the V4 mode.

Does this make 09 5.3s fairly reliable?

My 2011 escalade 6.2 had a lifter failure and wore the cam lobe. Which cam kit would you recommend to do the full DOD delete?

Many kits sold have the VLOM that does not have the solenoid plug. I reached out to many AFM DIYers and they said they never got a CEL or codes just leaving the connector unplugged. 2 questions: - do you know a specific way to avoid any codes on the first startup? - if using HPTuners, can you write up or show a quick video on what to do in the software to avoid any codes or no throttle response on first startup? If

Is it worth it dod delete as a car you drive everyday 2007 caddlic escalade 6.2

I have good oil pressure in my 07 avalanche with a 5.3 and no engine light on... But I can definitely hear the push rod slapping the rocker arm! the noise seems to be from the drivers side. Its bad news no matter how you slice it, the noise started as a tick and its loud now, and i want to park it! My question is does the cel light not always come on indicating the misfire code?

How the hell you get the lower back head bolts out!

awesome videos, glad i came across this channel. thank you for your time, expertise, and knowledge. it sure helps

Great video series I followed your cam swap series and they were a great help in installing my cam on my 15 Sierra l83. I recently finished everything up had my ECM tuned and I am getting error codes for coil control circuit on cylinders 1,3 and 5 I’ve moved plugs and wires around checked for loose connections including the two grounds on the drivers side head. Just curious if you had heard of anything like this or had any insight to what could be going on? Thanks again for the great videos.

I'm going to do mine. I hate that system

What is your opinion on the oil pump leave the high pressure and plug the relief valve in the oil pan or get a standard oil pump and plug the relief valve in the pan ?

I just purchased a 2011 Yukon with 170k miles. I have noticed a misfire at idle is it safe to say that I need to have this done or is possible all I need is a basic tune up.

Question what do you do with the left over conector

Okay we did the dod delete kit from yall on our 2008 Chevy Tahoe hybrid and we are having issues still.....no power when driving when in idle shakes badly and when it is in very low idel we have a bad rattle grinding type sound....got into computer and the dod inside the computer was showing disabled already what else are we missing??? We have also replaced the cam shaft with a different one that came out of a ss camero

Is there a delete kit for the new L84 5.3 yet? I've been looking for camshaft and lifter kits for it and can't find anything.

Do you think using the needler vibrating tool straight on the push rod would release the collapsed lifter ?

I’m sorry brother, but I’m in the middle of one of these on a 2019 sierra. And I’m not getting the info on where to put these plugs, this is an lt engine not an ls. Please help

I'm having the issue of p304 I changed the fuel injector, coil, spark plug, and wire. Still showing a cylinder #4 misfire, no noticeable lifter tick, Not sure what else to check other than taking off the head and seeing if there's an issue with a lifter

Thanks for the videos. What causes it to stick like that? It's catching towards the bottom, but if it's not grime build up is it getting warped over time and that is causing that extra tension not letting it release and if so why are the others which are always in use not having the same issue, because they are more regularly lubed?

Could you please help me out, which cam can i use when deleting dod/afm? i have an L92 and L9H, can i use one of thhem? escalade 2010 (e85)

Could bad afm cause vibrations when engine goes to V4 mode?

CPR, I did a DoD delete with new cam, new lifters, new VLOM, and flash for my ECM. For the second time, the ECM has shorted out and the car won't start. Any ideas on what could be causing this. It is expensive to tow it to a shop, have the ECM replaced and flashed, then limp on 4 cylinders down to the tuner shop to get the new ECM flashed. Help!

Might be a stupid question but do you need to change the cam shaft position sensor?

Hello love your videos! I replaced bad lifters on left head#1 misfire on number five now the dod activates all the time number one misfire .i changed installed new valve lifter pan under intake put back together and still have the #1 misfire both valves stop upon start they rotate 3 time and I assume go into dod mode and shut those lifters down. . And traction control activate. I have a 301 misfire code. And heavy skip. Any suggestions

Thanks for all your videos. They was a lot of help through the process. I have a 2012 Chevy Suburban that I done to AFM DOD delete with camshaft swap, kept VVT. Also had the ECM tuned. Had a question to see if you could help me out with. Everything seems to be fine, runs and idles fine but once the engine starts getting warm if I barely touch the accelerator The engine idles up high and hangs (2,500-3,000rpm) at a high idle for 5 to 10 seconds and then slowly comes back down. Do you have any idea what may be causing this issue? Do I need to relearn cam? Thanks

I am working on my uncles truck 2010 with a 5.3 he has a lifter that is collapsed and it has 20 pounds of compression on number four and number two has 170 pounds what I was wondering do you have any recommendations to slow down the oil consumption once I fix the lifter problem I have heard about the driver side valve cover and the deflector shield that goes on the oil pan what is your recommendations to help slow down the oil consumption thanks I really appreciate all your time on these videos you do a excellent job

I have a misfire on cylinder 4 along with loud lifter tick. Would this be the same issue? I checked plugs, wires, coil pack and all are good. Will this kit fix my issue? Thanks

Really appreciate your videos. I have a 2012 Tahoe and just installed a DOD kit and the truck will not start. I’ve called the people that I bought the kit from and they said that it isn’t starting because I soaked the lifters in oil. Does that sound correct? All brand new lifters installed. Thanks in advance!

Will it trip codes if you do the DOD kit prior to disabling the AFM with a tuner or will it run?

Didn't know I'd be watching brain surgery.. Awesome detail!

How many miles on this vehicle? I see these videos all the time but people never mention the miles. And wouldn’t this AFM system benefit from more frequent oil changes than these modern maintenance intervals systems call for?

Hey man I did a full delete using cam springs lifter ect. Its been tuned an running good for about 2months then I got a p3401,p3425 code but the volm was replace with a flat non afm cover when the sawp was done ..do you have any ideas what is wrong

Are you suppose to replace the lifter trays when replacing the lifters

while im in process of doing this myself and while I do more research, is that cam solenoid at the end of factory cam needed after a cam swap? 6.0 cam swap for my 5.3

Does anyone know if I would have to do a vvt delete if I do a dod/afm on 2013 suburban

How do I use my 2000 dbw harness an computer with a gen 4 engine

Gas the Music your voice is way more important.

Can we camm are Chevy suburban in California

So theoretically you could disable it and and never have an issue as long as those parts are in good shape?

That motor already has a dod delete valley pan

Is there a way to deleted or manipulate the computer with hptunes thanks

yes i am buying my lifters to remove my dod off my 2007 suburban with 5.3 lc9 engine when i look up ls7 lifters on internet will any work or are there diffrent ls7 lifters

Do you guys have Emissions there? We had an 07 silverado with a dod kit that we ended up not being able to pass emissions because of it. Ever had any issues with that? We’ve done like 5 valve jobs because of afms so this should save us a ton of time and money. Thanks man. As long as it doesn’t pop any codes from it and the monitors all set we can get it thru emissions I’m sure. I forget what the exact reason was for it not passing.

Can't you just somehow reset the computer system to not run with advance fuel management.

So question: when you do just tune and tune out dod will the chance of lifter collapse still exist since it’s never asked to collapse again? Thx

I wonder what GM does nowadays for that DOD system

Sir where is your shop located

Bro question::: 07 Tahoe LTZ 5.3L with over 200k miles. Been thinking about getting the engine change but am confused in whether get a used engine and break it down to replace all major parts to bring it to a new state as in 0 miles or just find a used engine with low miles and throw it in? Thanks

at 6:30 what are the symptoms if they are worm out? does it make sound?
