SDPC Tech Tips: 4.3L LV3 V6 DOD/AFM Delete
Вставка
- Опубліковано 25 бер 2021
- Nick goes over our new AFM/DOD Delete for the Ecotec3 4.3L V6 found in your 2014+ full size trucks, SUVs and fleet vehicles. These are almost direct copies of their bigger brothers the L83 and L86, just missing two cylinders. Unfortunately, they also inherited the dreaded DOD lifters to put it into 4 cylinder mode.
We have put together a delete package for your daily driver, or maybe you've decided to buck the trend of "LS Swap, bro!" and take one out of the salvage yard for a restomod, sandrail, rock crawler, or track weapon.

Working on a 4.3L swap, installing a cam or anything of the sort? TAG US! We'd love to see/hear these things in action.
What kind of power output do these cams add? I was looking at the stage 2
any dynos with these yet interested in stage 1

Nick, one thing you should do and emphasize to the viewers who may be shade tree mechanics and or first timers with doing engine work, is to make sure and clean the mating surfaces before applying the silicone sealer.
I recommend using acetone and a "white lint free" rag or as many as it takes, and apply acetone to the rag and wipe, wipe, wipe the mating surfaces, until the rag is NO LONGER picking up any oil residue. BTW..... why acetone ? Both brake clean and alcohol leave a residue. Brake clean has a propellant in the can. Alcohol is seldom pure. I used to do chemical anodizing of aluminum jet engine containment cases. The anodizing chemical will ALWAYS tell you if there's ANY contamination on the surface metal, because it doesn't etch if a contaminant is present. Acetone was the only truly effective cleanser. You'll be surprised how much oil that isn't visible and can't be felt, is trapped in the metal. That acetone will draw it out, to be wiped off, and the acetone will evaporate completely, leaving a perfectly clean surface for the silicone's acid to etch itself to. Silicone sealer will not bond well if there's any oil in the mating surfaces material. This is especially important for older engines that have some cylinder and piston ring wear, because there will be more blow by going into the crankcase, which can cause a positive crankcase pressure. When that happens any oil on the internal surfaces is going to find a way out. Which means, for instance the front timing cover, if it wasn't properly sealed, is going to leak. The customer or owner of the vehicle is going to be unhappy if his or her formerly dry clean engine, now seeps oil.
An ounce of prevention goes a long way...
Outstanding video. I hope you keep this up for many years. I really like this engine. I enjoyed all the tidbits of info about this engine. I hope I never have AFM issues.
This is very well done and explained. Very thorough and well narrated. I'm impressed. I'm impressed!
This is very interesting! My 1983 Chevy Impala has the second iteration of the 1st gen, small block based 90 V6, the 229 3.8 liter. I absolutely love the design. Effective power, in a simple, and conveniently compact configuration. Tough as nails, and always ready to go. It's awesome that it got an upgrade, in LS style architecture
Have a 4.3L in my '17 Sierra. Great engine. Saved $2000 CAD over the V8. Good power. Even with heavy LT 34" tires, loaded with my wife, 3 kids, 2 dogs and my 6000lb 5th wheel trailer. I don't see a lack of power, fuel economy is decent too. Granted I have done the intake, some exhaust work and a flash tune... Funny enough tho, I kinda like the V4 chug when I'm just rolling along through town at 1200-1300 rpm. Zero issues with the engine. Granted it's only got about 55k miles/90k kms...
@Edmund P. Lewis just a generic locally made straight through. Not sure the brand.
Where you get the tune?

Oh heck yeah!! I’ve been waiting so long for a kit to come out on this! Thank you guys!
You are really good at explaining this stuff. Thank you.
Great video! I’ve always loved the little Mighty Mouse! People can be cheap but I hope they will listen to your warnings!
U would have made a gr8 👍 teacher. Nice work . 👏. Robert Australia 🇦🇺
4👍's up thanks again for having us all over for the great news
Very interesting little motor.
Really stoked for these little engines. I'd love throw one into a lil s10 or blazer
I'm watching this and pricing the swap. A good complete wrecker motor is worth more than almost any s-10 or blazer. Definitely a passion project. In the midwest I'm seeing $4k average.
Looks. Pricey its fine if you already have it and need to do the delete
I just want a 03-05 4.3 swap but
there are not a lot of videos of
I personally use carbon fiber reeds from old two stroke engines as scrapers. They work surprisingly well on suck sealant.
On your comments regarding the balance shaft. 1,000,000% agree with you. There is ZERO REASON to delete the balance shaft. There is no benefit Horsepowerwise and no benefit Torquewise. The balance shaft is a great part for this motor and it only creates issues at install and removal. If you don't have time to deal with balance shafts, then stop doing motors.
The imbalance created by removing it would most likely ROB the engine of way more power than anything close to what deleting it may save.
Very informative! I have 2 suggestions. If the cam retainer plate and bolts aren't very expensive, it seems they should be included in the kit. How about including some sort of simple cam removal/installation tool. Would a 3D printed item be strong enough? Otherwise a simple drilled plate with t-handle.
I have the AFM delete kit and I am in the middle of a truck operation. I HIGHLY recommend getting a Chilton's manual or GM Service Advisories if you want to do this to a 2018 4.3 or 5.3 Silverado. The 4.3 2018 is a tricky beast to get to the actual work. The electronic steering rack and the front differential must be removed to get to the oil pan. It's easier than pulling the engine but still a lot of tedious work. I don't have the time to do a video on mine, but a full start to finish on the 4.3 LV3 - GEN 5 would be great to have online. Take pictures on your phone as you go through the disassembly, and it makes the rebuild much easier. I'm also doing short video clips on my phone to describe the process better than the manuals.
I got the oil pan down and I'm replacing the pickup tube and oil pump. I noticed that when I took all the bolts out to get to the tube it was loose! I thought it was supposed to be a press fit and I emailed tech support at Melling to ask their opinion and if they had a tool to insert their new one. The tube is 1.179" diameter, so the standard 3/4" tool won't work to press it into the receiver on the oil pan. Suggestions welcome on that one! - Thx!
I got a 14 lv3 v6 silverado. I'm currently on the predicament of engine pull or diff drop haha. May just tune out afm at this point.
No need to remove oil pan, or front differential or steering… not sure why your going through all that
I want this engine in my Grand National. It is a massive upgrade over the 3.8L or even the 3800 series 2/3. If I could find someone to modified an intake for me, I would buy a block and rebuilt it and slap one in my GN.
Use the stock intake. It works well.
The service manual says the oil pump alignment tool is not necessary if you are installing a new oil pump. Says it will "self align" I don't understand the difference. It simply says to push up while tourqing the bolts. Can you help me understand why this is?
I broker a head bolt so i took both heads of to take it out then I reused the new bolts that were stretched days before and now I have a huge oil dump when I rev the engine
loved the video, I am putting a LV3 in a jeep crawler, I have a ECM and Harness that has deleted the AFM/DOD. how many problems am i going to run into if i leave the AFM/DOD components in the engine?
Excellent video. Question im working on a 2018 GMC sierra 1500 4.3 lv3. 71600 miles the oil pressure is 40 psi but after engine gets warm maybe 20 mins later oil pressure go down t0 8 psi, i already replaced engine oil pump (with original ac delco) and still is doing the same thing. when i removed the oil pan everything was clean no metal shavings or dirt inside the oil pan, no play at rod berings everything was normal. note if i increase rpms the oil pressure go up. so what could be the problem
On my 2014 4.3, I often got a misfire code on #1. Then started getting lifter noise, again #1. Pulled the valve cover and found that the intake rocker had about 1/4” gap. Now I am in the middle of tear down and find that I can’t get that lifter out. It moves but has a dead stop with about 1/2” of lifter protruding from the top of the bore. I guess lifter will have to come out from the bottom. The DOD lifters never had a problem. I am planning on doing the delete, assuming the lifter bore is not damaged.
I wasted hours trying to get the dark links on the balance chain to line up for disassembly, make little sense why these weren`t lined up from Gm factory, your Video was very helpful.
I have this engine in a 2016 Silverado. Just turned 108,000 miles and no problems. Ignore the oil life monitor and change your oil every 5000 miles and change the PCV valve every 20,000 miles. Period. It will last. No $3000 deletes, no stupid OBD plug-ins, no catch cans needed; and no carbon build up with regular oil changes. The internet is full of 5.3 lifter horror stories, there’s no such litany of lifter horror stories with this engine. I found exactly one story of a lifter failure in this engine; it had close to 200,000 miles on it and had been starved of oil. This engine does not eat lifters like the V8’s do. Speaking to actual GM mechanics at four different dealerships and they relate that while they have done lots of lifter jobs in the V8 engines, they have never done a single lifter job in properly maintained LV3’s. Keep your oil changed and keep trucking.
Ok I’m curious now. I’d like to see this end up in a s10 blazer built for off road. Keeps it light and makes LS power
Really want to put this in my s15/jimmy street truck, should swap nicely
Someone needs to gave a swap kit for these to go in s series trucks. They're pretty neat engines
Gave =make
I placed my order for SDPC dod delete kit for my lv3 and selected a stage 2 cam with valve springs and upgraded high pressure lines for under the intake and will be matting it with a fresh 6L80 from dealership my only concern is where can I get a tune or who can tune after I swap everything please help!! Thanks in advance
I had some scuffs on my lifters and camshaft when I took them out. What's the root cause of the issue. Is it the VLOM itself or just the AFM lifters getting stuck? Cause my lifters weren't stuck when I tested prior to removing them. Should I also be replacing the oil pump?
Believe it or not 2014 4.3 one lifter collapsed and well yea I've changed oil and did a couple treatments to oil thinking it would go back to normal but it did not and I've been driving it from January 17th till now Oct 12th , still running the same, intermediate misfires and the lifter noise.
I have one of these and I just have it programed to not go into v4 mode. The oil pumps have a pretty severe issue of going out and they are extremely expensive to replace. It cost me 3800 at my local GMC dealer. Has anyone else had this issue? Also, would this potentially help save the oil pump?
How many lifters with spring does it use and how many with no spring? 6-6 or 4-8
Hey guys great videos I just tuned in after seeing you Dyno on the 4.3 . If I wanted just to buy one (lv3)from you (like the one on the Dyno turbo and all how much is it and would i need to supply the engine for the build? Thank you for your time.
NICE VIDEO.. SO WHAT R THE TORQUE SPECS FOR THE CAMSHAFT BOLT ACTUATOR PLEASE?
I just used the kit and fired the truck up after removing the AFM from the ECU. It's running really rough and I'm getting random misfire codes. The timing looked great and I took pics to record it, so I can share if you'd like to see them.
Well. Had to do a complete tear down again. I found out that I missed the timing any that caused the issue. We are all back together now and purring like a kitten.
I currently have a 97 sierra sl v6 (4.3L vortec) 5 spd. I have wanted to upgrade it and go with an aluminum engine. This would be great because it's all aluminum and makes some more power than my current 4.3L
Stick to yours
Just wanted to say thanks, gotta 2000 4.3 5 speed rwd It was garaged since 2007 I had a knocking in its idle wasn’t the plugs or the injector wires. What’s the deal at 42000 miles. It’s literally why I garaged it. I’m doing a restoration and have no clue how to make this vehicle my daily driver.

I first thought it was the DOD problem. I was going to try look for collapsed lifter but, did a Automatic Transmition Fluide flush of engine oil first, i think it may be slug.. I also checked the oil pressure screen, it was clean.
( I Don't know how well the oil was changed for the first 40,000 miles.)
I don't hear a lifter tapping but there is a lope or shake to the engine .... i think.
Did ATF flush but the engine light is still on.
The DOD does not switch from 6 to 4.
The oil pressure runs between 30 & 45 psi. I was wondering if the oil pump coil fails.. but you said it will put out 65 psi.
Is it possible for the ATM valve to fail.
can you help me figure this out.
I love my truck with this engine, I'm thinking about buying another engine to swap into my old firebird LOL
has anyone done a LV3 swap in early model S
10 like a 91 model ? i would love to have one in my 91 S 10
Could you use higher ratio rocker arms from a 5.3 kit and use on this engine to get more power since it's basically the same engine with 2 less cylinders?
I think they're identical anyway. These engines are near identical with the obvious parts that would be missing due to the lack of cylinders 7 and 8...
i have a 2016 chevy Silverado wt do i have this dod ?
The best ever.
Whats the torque. Spec on this heads. Thank you.
I've got an 18 raptor and have a MPT tuner , it's an animal . I would like to see a twin set up with some direct injection and aftermarket engine management run on the 4.3
Hmm
wouldn't this be a neat engine to substitute for the v8 in the Boss Hoss especially with a turbo like the Buick Grand National?
It's a pretty potent engine even in stock form. Basically equivalent to the older 4.8 V8. Super strong bottom end. Wouldn't bat an eye at 500hp under boost.
My dad's truck its a 2014 v6 lv3 yesterday on the highway loose power, traction control light,engine light start blinking all the time, they have a bad misfire cylinder 6 and start smoking. Do you think a bad dod system can be the problem and the dod delete kit fix my dad's truck .its just a question its because I don't know the symptoms wey the dod it's not working good

For Lv1 camshaft upgrade kits just fits straight in? no need to worry about lifters? also after some better springs and holley 650 inlet manifold for a buggy no injection or ecu etc but did ignition controller. It is to replace cracked scat v4.
Sorry to hear about the cracked V4 :(
The cam for the LV1 and LV3 are interchangable so you can run our Stage 1 and Stage 2 kit in your engine.
@@Sdpartscenter Thank you for the heads up as the Lv1 v6 is a dream come true as I always wanted to get the all alloy aftermarket TA Performace buick v6 block that used to be 5k usd till the Lv1 was available. The Lv1 is a beautiful simple lightweight engine but now to make it simpler carb, headers, ignition and stage 2 cam kit.
Dang it. Wish I would have watched this video before I took off the oil pump. We’ll I am still in the cleaning stage so I will reinstall the old pump and pan. Realign it using the old bolt marks and set up as best I can. Then set up the alignment tools against the old pump before removing again.
This is a Modernized version of the Chevy 4.3L V6.
Hi. I've got a '93 Chevy S10, 2.8L V6, 2WD, standard, and just had the T5 rebuilt. Also, just had to install a NuTech long block as the first ATK gave up the ghost after ~154k miles (drive it pretty hard with 2 leafs added to the rear to support shell, rack, lots of tools). I've kept up on suspension and drive train maintenance over the years, so I'm planning to keep it at least as long as the new engine will stand. Watching this video has got me wondering if one of these puppies could be shoe-horned in with that T5 stapled behind, Jesus take the wheel! Any thoughts? Thanks for the videos!
Sounds like a good idea to me. The new 4.3 is interchangeable with the old 4.3, which also went into the S10.
But then again, a 3.5 or 3.9L of the same engine family as the 2.8 would be pretty good, too. The 3.9 was put in Pontiac G6's and minivans, and had 240 HP.
@@andyharman3022 Thanks for the info. If I prematurely kill the NuTech, it will help me strategize. 😉

Does anyone know if you can use a commonly found LS flywheel locking tool on a LV3? A 2014 4.3 with 4x4. If not where to get one? Thanks
In all likelihood you should be able to. Same tooth count/diameter and almost identical bellhousing bolt pattern and starter location.
@@Sdpartscenter I did purchase one of Amazon and it was close, the teeth would not fully engage though so when I torqued on it to break the crank bolt loose, it slipped. I reformed it to make it engage the teeth better, (very soft metal) and it just bent and failed to hold the flywheel. I reshaped it again and welded a steel plate to the side of it to beef it up and finally was able to get the crank bolt loose.
Whats Interesting is these will be sought over engines, compared to the 2.7L turbo, when a turbo shells, you have no power.
Why not use the LV1 which doesn’t have DOD in the first place?
For simplicity's sake, yes getting an LV1 for your swap would be way more effective. But you'd definitely need to be on top of it when buying a pull-out because some people wouldn't really be able to tell you the difference.
We snagged this one so that we could see what all is involved in the LV3's AFM setup.
I have a 2018 4.3 anything for a custom camshaft kit?? Specifically a cam for boost
We are working on some custom grinds at the moment. It has been a tough going because of all the supplies shortages.

What bolt ons did you happen to find?
Very timely video. I'm thinking about doing an LV3 swap into a 4th-gen Camaro, replace the original 3.8L Buick. The LV3 hasn't gotten enough attention from the performance aftermarket. The LV3 was designed by GM to replace the Gen IV 4.8L V8. It makes the same power and torque with 0.5L less displacement. And it's E85 capable, and gains 30 HP running on the corn juice.
Its pointless. Get the 5.3. Or now the 2.7. The 2.7 wastes the 4.3
@@zackjay71 Not when you turbo the 4.3.
Sorry Andy. BIG correction. GM is FOS. No vehicle, even those labeled "E85", "FLEX FUEL" or similar can actually run on 85% ethanol. (They even run crappy on 10% ethanol) Illinois just initiated a class action against GM for this reason. DON'T USE E85!

We're working on that at the moment. We have a few performance grinds on the way.
@@Sdpartscenter please let me know when pre order is available! I have a wedding and a house tying money up, so a 5.3 swap is out of the question for the near future. If a custom grind is available for purchase with the kit I’d love to put a deposit in And be a guinea pig!

You can replace it, it would be about as difficult as doing an LS or LT swap just with a few different steps.
Since when do 4.3s have afm?; along with 4.8 and some 6.2s. Its cylinder deactivation mode, and drops from 8-4. Youre telling me they stuck it to drop 2 cylinders from 6 to 4??

Do all 4.3v6 have dod? I have a 2014 Silverado wt model, does my have it?
WT model should have the LV1 which does not have the AFM/DOD setup. It's the reason why we're able to do a delete at all on these.
Do you have a weight for the Long Block?
We do not know exact LV3 longblock weight. We need to find out, we should have that information soon.
Totaly forgot about this engine Looks just like the LS1 so Its basicly an 5.7 LS1 just with 2 cylinders less
Slightly larger bore than the LS1, plus all the differences of the LT engine series over the LS.
Could this swap in a 98 gmc jimmy aka s10 blazer
It's not a direct plug and play swap, but people have been swapping them into that platform already.
Wouldn't it be a lot easier to just get a good LV1 engine from a 2018-newer Chevy Express van? I have a 2021 Express Van and I'll tell you it drives like a V-8 but with better gas milage.
It would, the real challenge right now is in finding them because they get snatched up fast.
do you have a link for that oil pump alignment tool

What is the head bolt torque and rocker arm torque

would this 4.3L bolt up to a NV3500 or a T56???
There is not a pilot bearing provision deep enough. You would need to use a spacer from ICT Billet: sdparts.com/i-24502628
And a pilot bearing from a 5th gen Camaro SS: sdparts.com/i-19874014
If you don't use the spacer, you run the risk of cracking the block when you try to tighten the transmission down (we saw this happen on ls1tech).
@@Sdpartscenter thank you very much for that information
@@Sdpartscenter would it be better with the T56?
Does it need to be retuned when you did this delete?
Yes, just like with other DOD deletes, you need to disable those parts. You can't just use a OBDII dongle either, it has to be tuned.
Hey where can i find the part# for the dod delete kit because i see yall dont have it at the moment?
@@ismaelvillarreal6083 Hi Ismael, we're scrambling to get that taken care of. When we did the video, GM showed these cams in stock but then they suddenly disappeared. If you'd like, shoot us a PM on facebook and I'll try to keep you in the loop on when these cams show back up.
@@ismaelvillarreal6083 we have more cams on order, ill let you know when they are in stock!
@@ismaelvillarreal6083 We've got the parts back in stock!
Can you bolt up a V8 transmission to these?
Hi Mike, yes these come with the same automatics that the V8 trucks come with from the factory.
Manual transmissions require some additional steps to make them work, which we will be covering in a future video.
@@Sdpartscenter thank you for the response! I'm thinking a super lightweight combo with an LV3, QuickTime Bellhousing and TKX 5-speed (~100lbs).
You don't need to actually make the mistake to learn from the mistake!! 😙
Head torque specs for this one

💯
Thanks that cleared up alot for me let's ne know I'm not doing this myself
I would love to buy an aftermarket cam for mine
Hi Dann, it's in the works!
Could you just cut off the last 2 cylinders? Wouuld the layout jive with the shortened v8 cam?
@@safetyfirstintexas Lobe timings would be way off.
@@Sdpartscenter I'm watching this site!
Is this the same as the LF6?
Completely new generation motor. All it might share is displacement and that's about it.
Shame they didn't borrow heavily from the LT6!
Dohc would been nice!
If you'd like to do a 4.3 DOD delete in truck and make a video, I can do without my truck for a week. Only issue is I'm in Houston with stuck lifters.
What year is this motor
2014 and up.
It looks a lot easier when it's up in your teeth; working in the engine bay is still a little tight. Change a water pump and you'll know.
NASCAR BUSCH series used v6 engines when they had to put restrictor plates on the V8s and they were going 200mph.
Love the videos doing dod delete on l86 after watching some videos decided to order a dod kit and some other parts from scoggin-dickey called the salesman i talked to give me the info i asked for i asked if torque values where included he then advised me he recommended that customers should take it to a shop not knowing nothing about me. Needless to say i said ok thanks hung up phone and called btr.
That motor looks like it’s a green screen or something?
My ole 4.3 votrec gets fantastic gas mileage it’s in a Silverado wt with a nv3500 manual 5 speed. I get 514 miles to a tank of gas on the highway and 410 to a tank daily driving in town my wife Arcadia get 400 on the highway and 370 in town daily driving. Better on gas my ass. And my 4.3 with ported mercrusier heads is pushing 220 hp that’s plenty for me.
Such a Beautiful Shirt!!!!......Sounds Like You Need Some Oxygen??......Short on Breath??........Great Re-Build!!!......Lots of Good Information!!!!
5/16 equals 8mm
I'm going to get block for asking this. Why don't you just use HP Tuner to turn off DOD?
Some people do exactly that and will be just fine for some time as long as it is done before those lifters start to fail. It prolongs the life of those lifters but does not guarantee them from failing.
This kit is usually for those that want to delete it ahead of time or have had a failure already. We will have performance grinds soon to really help make this a worthwhile mod.
@@Sdpartscenter My question and your video made me use HP Tuner to raise my top limiter on my 2016 F165 (F150 2.7) to 120 mph. Wow, it is so much more fun than before. The stop/start stopped working for about a month for some reason.
What is D O D?
DOD = Displacement On Demand, or the fancier term is AFM = Active Fuel Management and now DFM = Dynamic Fuel Management
DOD/AFM is where a v8 equipped with the system will shut off 4 cylinders during low demand or cruising. The 4.3 LV3 V6 will shut off 2 cylinders.
DFM in the newer V8s can shut off any number of cylinders in any order, engineers with GM got it down to even just operating on one cylinder in testing.
@@Sdpartscenter how can I get some of the parts for this engine like the cambolt oil pump seal
5/16 is the same as 8mm. Just a fyi.
