HOW TO: CHEAP LS AFM/DOD CONVERSION. CHEAP, CHEAPER AND CHEAPEST OPTIONS. CONVERT FOR PERF CAM SWAPS

[@Dougduke8469]

On past LS1 cam swaps I’ve done we used the dowel rod method to pin the lifters up after spinning the cam to push the lifters up. We obviously weren’t changing lifters so we weren’t pulling the heads and we didn’t want the lifters to fall especially on those high mileage motors. I was always on edge hoping the lifters wouldn’t fall being the cars were F-Body and didn’t want to drop the cradle to get the pan off.

[@shadowopsairman1583]

Yeah i will be facing that on a swap to the Texas Speed Chopacabra in my LR4 (4.8L LS1 Iron Block). Really don't want to take the heads off at all as they have mls gaskets and im not replacing the lifters anyway

[@bluecollarhotrods9781]

@@shadowopsairman1583 get a piece of dowel rod and cut it in half. You spin the cam to knock the lifters into the trays. Then slide the dowel rods in to keep them from falling down. I've been doing that with an $0.88 piece of dowel rod for over a decade. It works well and doesn't harm anything.

[@LucoreAuto]

What freaking fantastic timing for this! We are literally just putting a 6.2 Denali back together that suffered from a failure even "with the dongle installed". It's terrifying how many of these trucks are out there even well cared for that have the ticking time bomb of AFM/DOD under the hood. Doing it outside the truck is certainly a lot easier to do than when it's between those big honking fenders. However. If you HAD to do it in a truck, how would YOU do it? Pull the cab and work on it in the chassis? Or disassemble the nose and attack it through the front? The kit we prefer is the full boat from Texas Speed, new lifters, gaskets, bolts, "hammer home plugs", no more factory installed GM failures! We're cab off kind of folks, but maaaaan the internet know it alls HATE it! Great video as always Richard always appreciate you giving some good honest real world experience in these videos Sir!

[@2010bigfathen]

Taking the cab off of a 1500 GM to work on the engine is very unnecessary. I never remove body sheet metal but if I were going to it would be the inner fenders and I’m thinking they’re plastic covered with some sort of cloth

[@catbird1759]

Richard, I don't like just the cover and orings blocking of the oil ports on top. #1 is possible warpage of the plate.#2 oring failure. Piece of mind is plugging them. The nice plate can still be installed. Thanks for all the educational videos.

[@grominwithrob1339]

I am kicking myself in the butt. A few weeks back I did an intake manifold gasket and had to retort the valley cover because it had some loose bolts. I wish I would have plugged the ports and used the ITC cover. I disabled DOD with HP Tuners long ago. I used HP Tuners because I knew I would do the full delete at some time and wanted to be able to tune a new cam. I am planning for the spring. If I am taking the engine out, I am going to do a complete tear down and replace all the bearings, lifters, springs, head covers, headers, exhaust, cam and HF/HV oil pump. The works, because if I’m going in, I’m going all the way. I’ve never tore down an engine before, but good lord, the LS engine is stupid easy to work on,…besides rusted header bolts!!🤣😂🤣😂 I really love the LC9 in my pickup although I wish it had 799 heads, but I can’t complain with my lower compression reliability. 😂😂. Oh, I also want to do the torque converter at the same time as well as replace all my coolant lines and hoses to braided and silicone. I also want to upgrade my existing trans cooler to a larger one just for giggles. I know it is going to be expensive, but I really don’t want to do it again because I missed the perfect opportunity to do it with the motor out and wide open, easy access to every thing. Thanks for the awesome content and for covering so much on the cams!! I am pretty sure it’s the BTR TruckNorris for me. I want to retain as much down low torque as I can because this is still going to be my daily driver for scooting around the city. I also don’t care about crazy top end power because I am not interested in Racing or I would pick a different vehicle. 😂😂😂

[@stephenhodge6441]

[@kevinshasteen5682]

Cheaper DOD Delete would be an A-37 wheel bearing like a Timken37, or WTA-37 wheel bearing; cut the race and use the taper shaped hardened steel bearings, tap them in as well with a hammer. One of your commenters mentioned the A-37 wheel bearing already. An even cheaper option is to tap the holes w/a 3/8-16 tap and use set screws; use a vaccum while tapping to keep the metal from going where you dont want it to go. For good measure you should still use the valley pan w/their o'rings; so yes the ICT cover with its bling affect can still be used

[@shmuck66]

I know this is a year old comment, but fill the hole with grease first. It will absolutely prevent and trap any accidental shavings from going down. Then a blast of compressed air in the opposite hole will blast the chips up and out, along with a vacuum sucking it out too. Can't be too careful when doing this in an oil gallery.

[@alexanderjones6383]

I did the GM valley cover AND the plugs later on....just because I was worried that the o-rings might fail down the road and start to bleed off oil pressure. Never replaced the oil pump. C'mon now. 154K on donor LH6. Keeping it sloppy.

[@265powerglide]

The valley cover with the solenoids is called a Valve Lifter Oil Manifold or VLOM. Its job is to direct the flow of pressurized engine oil to the active fuel management valve lifters. The VLOM doesn't bleed off oil pressure from the lifters to collapse them. The VLOM actually applies pressurized oil to the AFM lifters via the eight towers cast into the block when cylinder deactivation is requested by the ECM. Using the the small plugs to block the flow from the VLOM is the best (and cheapest) way to deactivate AFM when doing a cam and lifter swap. The VLOM remains in place and is still connected to the ECM. As far as the ECM is concerned the AFM system is still working. If you replace the VLOM with a valley plate with O-rings the ECM will throw a code because it can't see the VLOM solenoids and the check engine light will come on. This can be corrected by reprogramming the ECM but this may cause a problem passing a smog check.

[@richardholdener1727]

thnx for the info

[@MonzaRacer]

Yeah but I've seen three come in with engine run ability when it tries to activate the damn lifters it kills the DOD cylinders corresponding injector if not dialed out in software. At least on a stock type vehicle. Had local guy that ALL he did with his HP Tuners was kill GM DO/AFM, never tuned anything. Wouldn't even kill antitheft for people

[@265powerglide]

Your correct. The ECM must be reprogrammed to deactivate DOD/AFM no matter which method is used to keep fuel flowing to all cylinders. @@MonzaRacer

If your lifters and cam are fine, I don’t see why you couldn’t just plug the ports and run it. You’ll need to tune it regardless. The software is going to deactivate those cylinders if it’s not tuned.

Hey richard I just watched your video on afr and timing, and it got me wondering. Have you done a test or have any data on the effect incremental changes in compression has on power? Im building a gen 3 lm7, and im putting flat top pistons in it to raise the compression, but i also know milling the head/block will also raise compression. I think it would be a very interesting test to see if there are diminishing returns to milling your heads to raise compression, or to see what the limit to shortening the head is. I assume there will come a point that the stock push rod length comes into consideration, and maybe piston to valve clearance on bigger cams?

[@richardholdener1727]

milling the heads is limited to deck thickness and intake fitment (bolt hole alignment), power gains are in the order of 3-4% increase per 1 full point

[@richardholdener1727]

[@miguelramos7352]

I'm going to do a DOD delete on my 2008 GMC Sierra Crew Cab 5.3, do I have to change the Camshaft and if I do why? Thank you.

[@richardholdener1727]

yes

[@Cherokee-sz7xi]

So can you just do the plugs,,,?

[@bobroberts2371]

I'm aware that the stock AFM cam is different then a non AFM and just installing regular lifters will cause the engine to run poorly. I haven't been able to find out what specifically is different with the AFM cam and why there needs to be a difference.

[@THEFERMANATOR]

The AFM cams have more lift on the lobes that use the afm lifters than the lobes that use regular lifters. So if you put regular lifters in them, you will have 4 cylinders with more lift and duration than the 4 non afm cylinders creating a power imbalance.

[@bobroberts2371]

@@THEFERMANATOR Thanks. So the AFM lifters are more " squishy " in normal operation and the lobe has higher lift / duration to compensate?

Do i have to tune after installing truck Norris cam?

Okay so I’m back with a question 🙋‍♂️ if I call BTR and explain what path i would like to take with my pickup would they be able to help me pick what I need over the phone

[@richardholdener1727]

yes-or you can ask here or on my live feed

[@TheWagRanch]

Wait, no lube on the cam?

[@Black__hoodie]

Do you have to replace the cam when doing this? I got a 5th gen I was just for now wanting to do intake headers and exhaust

[@richardholdener1727]

YES IF YOU HAVE A DOD CAM

[@mattcross428]

I'd love to see a video where you just change the lifters in a dod LS run it an see if you get misfires like everyone says. So dod cam ls7 lifters an turn dod off in the tune.

[@richardholdener1727]

dod cam has lobes specific to the DOD-why would you change the lifters and not the cam?

[@mattcross428]

@@richardholdener1727 I'd like to see it in a video that way I can show to my customers when the want to argue with me. I get the same response I've had it turned off in the ecm an it runs fine your just trying to get 400 more buck out of me for the cam.. see where I'm going. I get it but if I can send them a video of it causing miss fires maybe just maybe they'll believe me if they can see it. I live in missouri you know the show me state

Hey Richard great video So iv seen or read u can delete AFM with a tune im guessing this isn’t true after watching ur video. I have 2015 Silverado with the L83 and had lifter fail with 39,000 miles. I do get great fuel mileage seen 24.8 on highway and get 15 mpg average. Would it be the same process to delete my engine than urs. Please let me know Great stuff as always Thank you

[@richardholdener1727]

same basic procedure
