SDPC Tech Tips: DOD/AFM Delete 101 

Bert Kreisher is the master of the LS

If you're going that deep, remove the AFM lifters and solenoid cover, change the oil pump to a standard one and never worry about it again. The internals on the LS swap over pretty easy. Would also be a good time to put in a non AFM cam. Surprisingly easy to rebuild one of these engines

What about removing the safety relief valve and adding a plug in the oil pan?

You Answered all my questions in one video thanks man!!

great info... I believe a greater volume pump would be a improvement over stock... AFM delete and a slightly improved cam would make a very dependable runner...

If you’re in Metro Atlanta area, for same price or less than the cost of a Range module.. get a base tune. ✅More power ✅Raised speed governor ✅Quicker trans shifts ✅Less pedal lag for DBW ✅Disable V4 mode on AFM engines highly recommended with no loss in mpg. ✅Adjust for bigger tires & or gear change GM 99 to 2015 with 4.8, 5.3, 6.0 & 6.2 great value for $150. Newer Years DM your year and model for pricing. This is performed by recalibration of the drivetrain computer(s). Completed usually within 20 minutes.

All this dod BS makes me want to just go with a classic 350 sbc

Too bad GMC didn't just step up and fix the problem for us when it was under warranty and complained out the lifter noise.

After this operation will the patient still need 8 quarts oil?

Why would want that gives you a v4 aren’t you building it for up not fuel economy

I have a 2011 Sierra and truck is just sluggish with the afm when it kicks into v4 mode .. doesn’t tick much at all unless it’s super cold out .. it has 170k on it now .. would it be hurting something or potentially end up hurting something if I just do the plug in afm dod DISABLER? Or would I essentially be pissing in the wind ??

Thank you sir for very informative vedeo i learned a lot now i can do it my own.thank you very much.

Quick question this might be a little bit off topic but what do you think about getting a range for a 2020 suburban to get rid of the V 4 mode

I have a question and hopefully I can get a solid answer. I have a range dod disabler and a non afm valley installed but still running the dod lifters and cam. Blocking the oil tunnels going to cause problems with the engine or build up pressure and activate the lifters. Thanks in advance.

My local tune shop wants 1000 (cdn) to tune out dod if I replace the cam/lifters in my 2017 Sierra. They want 450 just to turn it off. Why the significant increase in price? Why cant you just replace the afm lifters with normal roller lifters, leave the oe dod cam, and simply turn off the system?

I got a 2010 Silverado. Never had 1 issue up till this week and -20 reg air temp. Now I'm getting the p3400 code which is this. Can cold mess with dod and afm? I have no tic no tap it did fall on its face and miss. A few times. Would cold mess with it at all? 141k never ever missed a beat. Up to literally now

I want to purchase a lifter and camshaft kit for my 2017 Chevy Silverado . Do you know any website with great review and products to go away from AFM DOD delete.

Okay so I have an 09 LH 6 even though I don't have to change the oil pump do I still have to do anything about the oil relief in the pan? Or do I just leave that alone?

Does the oil bypass in the pan have to be plugged?

I did a DOD delete and plugged the holes and used a flat-type manifold cover. My question is what do I do with the electrical connector that plugged into the DOD factory manifold. I have a 2009 Pontiac g8gt. Thanks

With the l99 engine from a 2010 camaro do I have to plug the valve in the oil pan?

Hey Scoggin, i just done a DOD/AFM delete on my 2007 Suburban 5.3... Its a Texas Speed kit that comes with everything "Cam,lifters, valley cap etc" after startup i have smoke "doesn't smell like oil or anything" and does have power starts right up and runs so smooth @ idle but under throttle it acts like its running on 4 cylinders instead of 8. Will I need my suburban tuned to get rid of this issues or is the issues somewhere else?

I am wondering how to find someone to tune the computer after the rebuild is finished

I want reliabilitt. Increase in horsepower qould be bice too. Not looking for noise either

Why not just get a Range Technology dongle that disables V4 mode for $199 and be done with it. You can unplug it for smog inspections and plug it back in after you pass with no problems. What’s the need for all these extra parts and expense???????????

Pour in marvels mystery oil or sea foam in your crankcase but not both at the same time be sure to read the instructions ....your problem is sticky engine deposits that keeps the lifter cup in a stuck down position leaving clearance for the push rod to rattle around and then tap when the clearance is taken up

I’m going to do this on my g8 with the l76, and I’ve been looking into the Btr stage 2, can I use stock pushrods or do I need to install different ones

Thanks for the info

If you’re in the metro Atlanta area I disable this feature for $150 up to 2016 models. 2017 & 2018 add $100. Less pedal lag, raised speed limiter and more power included at no additional charge.

What is the part number for a stock replacement cam for my 08 5.3. An where can you get it. Thanks

Tons of people going with a plug in dod tune delete or so that’s how it’s advertised. When adding this plug in you’re still using the afm lifters and cam so you’re essentially wasting your money correct?

I put (non dod ket) on my 2015 tahoe, and I deactivate dod program, but I get P0011 camshaft position!! what is the wrong for that?? Thanks.

If you replace the valley cover to a non dod do you just leave the connector disconnected? and it won’t throw a check engine light ?

What’s the difference between the ones you mentioned and the Gen V LTs? Same system, different results? Thanks. Great info.

It’s a terrible design they had to make for bs epa and fuel economy standards and it saves literally .5-1 gallon of fuel 😑 should’ve come factory with LS7 hydraulic roller lifters would never fail. Now I’m stuck doing a AMS racing DOD delete kit this weekend cause of this terrible lifter design 😂

Where can I get this done? Who can generally do it? How much does it cost?

I have never heard of replacing the camshaft. If you have to place the camshaft which I can not fathom why you should have to. I also believe that when you are replacing the lifters & push rods, & rocker arms, all should be replaced than only on the cylinders de-activated by the ARM, DOD, DDOD systems.

System is shit and crap u only save a gallon per full tank of gas on this system..and when it fails which mine has, cost me 2000.00 in parts and additional $$$ in labor...garbage system 💩💩💩

Tap and thread the oil towers in the valley with 3/8-16 ( only with engine completely apart)

Why the cam I've deleted this system by plugging the holes , the vehicle ran fine.

What I'd like to know is how GM came out with such unreliable garbage? It's no wonder why the Japanese are selling all the cars!

Nice vids. I'm from the philippines. I already have disabled the AFM via HP Tuner. I started scanning my computer and it starting to trow codes like P3401, P3425, P3441, P3449 and P3400. Is this normal?

If you guy want I have a niche in this DOD stuff I would love to work with your company. Colab with you via parts sales perhaps. I could help push your products if you give me or my customers some sort of incentive. Contact me if you interested in working something out. Good video btw wish I would have did so nicely on my first few on this system.

That system is a piece of Junk Don't Sugar coat it! It leads to premature engine failure and not much better MPG at all! GM tell the EPA to cram it the next Silverado you Build and Give us a real small block back.

What do you need to do with the electronics, if anything, when you do the mechanical delete? I have a 2011 1500 with a 5.3.

If I use the kit with the plugs I noticed you guys don't say anything about what valley cover to use? Do you take apart the original and remove the dod stuff attached to it or you have to do the non dod valley pan anyways?

Solenoids fail and valley plate screens clog

Does anyone who does this in denver, phoenix? Albuquerque?

Nice video. Been reading a bit that some guys who have the oil pan off are running a threaded plug of some type to block oil flow up to the old valley pan. Doesn't make sense to me, as the oil pressure sending unit is fed off of that too. Anything on this?

Ok I would really appreciate some input, so I bought a truck for 7 grand and it had a dod delete well it has a misfire light going off check engine light is flashing 2007 Tahoe so come to find out he did the non dod lifters and blocked the towers but didn’t do the camshaft, so what I wanna know is do I just need a tune or do I need to do a camshaft, and it ha low oil pressure like 15 psi at idle 40 when driving on road so I did the oil pick up tube gasket and that didn’t help so do I need an oil pump or do I have low oil pressure cause the camshaft wasn’t replaced

Cual es el precio del kit para quitar el AFM de una silverado 4.3 2016 ??

What about a Non dod valley cover with the O ring, on a engine that still has the dod lifters and cam intact?

My care light problems .. On .. What off.

I got a question can I use the cams and lifters from an o4 avalanche has lm7 heads to do a afm delete

I bought an edge pro Ht2 programmer and disabled the afm. I have an "10" sierra 1500 with 5.3, it also burns oil, and used to eat sparkplugs before I disabled the afm. Will it continue to still eat sparkplugs, and burn oil? I'm looking into the delete kit and found a mechanic to do it. I'm at 120,000, does it sound like anything else should be looked at before pulling the trigger? Ps I just bought the truck🤦

When he said, good system...works fairley well.....Lost all respect

I have a 2007 Impala 3.9, the lifters with the springs failed. For replacement I got the regular lifters along with the full gasket kit and the lifter retainers. Can I use the Camshalf that is already in the engine? and do I have to have something to block off the oil?

Do you need to deactivate this function in the software ? What about the injection and ignition cut of?

Will this kit fit a 2007 chevy avalanche LT 5.3 FLEX FUEL 2WD DRIVE? thank you!

Do you guys have 2007 caddlic escalade 6.2 kits i want to do the lifters and the cam i just want the best thing for my caddlic 6.2 it has some miles now im around 190k and I just want to refresh everything in it

Good Video! I have a 2007 tahoe with 180,000miles, I installed the AFM range disabler and replaced the updated valve cover back when I bought the tahoe, close to 8 years ago! The last six months ive noticed higher than usual oil consumption and a strong vacuum from the oil fill cap when car is running. Local shop did a quick check on the pcv valve and completed a smoke test for leaks all good there. They even checked the compression on the cylinders and also ok, there's no check engine codes, no white smoke from the tailpipe and no other noise that would indicate failing lifters. They shop said oil rings are the culprit for the oil consumption. My question for you guys is do you agree with the diagnostic and what is your recommendation moving forward, make repairs now or is there something else that could be done before they open her up?

With the "bullet" pressed in plugs, can you reuse the dod valley cover, or do you still need a non dod cover?

Lifters are under the haeads and a pain in the ass to replace plus super expensive

Is it recommended to change the timing chain as well?

I want to delete dod only and not the VVT so mechanically do I have to replace the Cam shaft and the lifters ? If I leave dod connector unplugged would the engine work normally with the dod lifters there ?

Is this the same kit for the l83 engine?

I'm putting a 5.3 ls out of a chevy Silverado 2010 with 6l80 transmission also it's going in a 1997 s10 pickup single cab can I use the stock oilpan from the Silverado without having to cut my s10 or do I need to change the oilpan if so which one do I need I really need your help

What's the cost of deleting the dod system with the kit and a new regular/mild camshaft?

Having a hard time locating a Cam non afm dod non vvt 07 5.3l would you happen to know?

If my truck is running fine currently , will a simple custom tune turning off dod prevent this issue from happening ?

I have a 2005 envoy Denali I think my DOD was disconnected from the factory I have the valley cover but it's not plugged in so do I have the dod lifters probably in there?

Would I have to get it tuned or reprogrammed?

So I've done my share of these lifter replacements and one common issue that was not mentioned is the lifter guides and what happens to the lifter as the guide wears out .but thats not my question .So when the ECM can no longer control the DOD it puts the vehicle in limp mode .You didn't state anything about this .How do you get around this issue?

Fuck gmc sierra motor problems!!!

AFM is the number 1 reason I have no interest in trucks newer than 07 "Classic body style"

I can't seem to find an answer as to why this kit is needed if it can disable DOD through the ECU for significantly cheaper? Not being snarky, just trying to understand.

These PoS AFM systems dont last past 150k. If the owner of the vehicle is lucky the best they can hope for is those 'special little lifters' stay collapsed and not cause further damage.

What are the chances that the steel taps would make the valley crack over time? I see the concept but the other valley cover seems better.

I have a 2017 Silverado with the 6.2, I bought a Texas Speed DOD Delete kit with the stock non DOD camshaft and GM performance ls7 lifters. Am i ok to use the stock pushrod length(7.850") if everything else is stock or do i need to buy the tool and check the length? Also is anything else needed to be done to the VLOM cover if youre using the 8 DOD plugs?

Do i have to plug the pressure release valve in the oil pan ?

I have a low pressure on a 2007 tahoe 4.3 i already change the sensor the oil pump and the tube and gaskets at the oil pan Some one told me this part may be the problem do you know if this part cause low oil pressure???

So what years for trucks does this fit?

so what does the kit to delete the afm syestem cost?

if you do the DOD delete kit, do you have to flash the PCM to erase the management system

Hi there, does it apply to escalade 2023?

Does the DOD delete require a new tune?

I have a 5.3 and got a plug in afm disabler, can I still use 0-20 oil or would I need to upgrade to 5-30? Vehicle barely has 50k miles

I have just purchased a 2022 Chev. Silverado. What do I need to do to eliminate the AFM system on this truck? What's it gonna cost? It has low milage. 17,000. The other thing is, will it mess with my warranty?

I will be deleting the DOD and VVT what kind of timing set should I go with? Do you offer the timing set? I have a 2014 Chevrolet Silverado 1500 LT. I also want a 3 bolt cam possibly stage 1 close to stock so I won’t have to change the pushrods or springs.

Why do you need to remove the cylinder heads? I thought you could remove the lifters with them in place.

Hey does it matter which way you put the non dod lifters in as far as oil hole position

Very helpful

I have a 07 3.9 impala and I installed a 09 3.9 motor so basically I deleted the afm right and I also put the computer out the 09 in there so what else will I have to do because with me having a different motor I already have the stuff that I would have to change on the 07 motor

I understand this video was 4 yrs ago but I have an issue today, changed everything on the dod delete kit stock cam, lifters, gaskets, 4.8 valley cover on a 08 1500 and for some reason I keeps throwing codes for the 1,4,6,7 solenoids and is preventing those same injections from working. I bought the little box off the internet & the issue remains

Great video. Do I need to tune the truck after installing the kit?

I did a dod delete I chang the cam and lifters still ticking and low oil level

Don’t they sell completely dod delete engine now . Thinking about getting long block for my 2011 5.3 instead of paying for new lifters and valve job

I have a che ticket suburban 2010 5.3 with a VVT sprocket, I changed the selenoid cover for a flat one / it does not have an AFM deactivation sensor / and now 4 cylinders do not work / what can I do?

Where can I find price for a delete kit with VLOM,lifters,cam and oil pressure relief valve?

Just flash the ecu to disable dod thats all no need to replace parts
