They Deleted the DOD and The Lifters STILL FAILED 🤔

Hey Good People,
I had a beautiful Chevrolet Camaro in the shop this week. It had the LT 6.2 engine with the DOD delete. Unfortunately, it still found its way to my shop for lifter failure. I couldn't believe it. Take a look at the video to to discover what happened....

Excellent vid, some serious diag skills, your customers are lucky to have you, a knowledgeable and honest mechanic. This is why as much as the sound of extra power is always appealing, outcomes like this or worse are always more common after doing such mods.

[@DADDY-ww4ox]

Thanks doctor, how about if you turn the crank shaft to the point there's no tension on that lifter then use the magnet to pull it out

[@feelgoodathletics2852]

I’m having the misfire in cylinder 2 and this going to be my next step to open to the engine more cause I’m still getting the codes after changing the fuel injector and spark plugs

[@S4flynlow]

I don’t have DOD and I lifter failure and rocker arm failure on a stock car. Oil changed every 5k with name brand synthetic.

[@qqq12qz]

Checks out. Why I quit being a mechanic. Every LS motor I worked on had at least 1 bent pushrod. Scam world to get you to buy another car in 5-10 years. If they built every Camaro like mine is now, they wouldn't make any money. It only cost a few thousand in parts to upgrade as well.

​@@S4flynlow Every Chevy V8 even the sticks still have the afm/dod its just deactivated in the manual at factory. Tuning it out doesnt fix the issue and will cost 5k to truely fix it. Needs normal cam, lifters, crank and retune. Gotta drop almost half the damn motor to do cam on the post 2008 LS3 V8'. The older LS was easy cam swap, not anymore.

[@mlieser1230]

Chrysler, GM and Ford are all having lifter failure issues. It appears that only one lifter fails, rather than several. I think that would rule out motor oil. The problem must lie in the roller needles. There must be a bad batch of needles. As with other components, I'm sure there are only a handful of bearing manufacturers. It's either a tolerance issue or a metallurgy issue. All can be narrowed down to one source. China.

[@mikevick7397]

So what it mean when oil shooting out the rocker arm ? Collapse lifter ??

[@Ben-yv7ir]

What causes that start up sound?

[@ramiroorona9027]

Mine sounds like that and it’s a 2023

[@turbotom416]

J.T. will be happy to see Ram isn't the only one with this problem.

[@AlexTheCarDoctor]

I know right! GM had it bad!

[@georgeluna8050]

​@@AlexTheCarDoctor do I have to replace the cam, if number 3 lifter when bad, because if I did, I remove the lifter on and check the cam by spinning little by little and it just had a little touch nothing like push in or scratch on the cam, cam look healthy?

[@AlexTheCarDoctor]

@@georgeluna8050 I will have to see something like that for myself to Judge

[@Mike__P]

ha! Yea but there's still a Ram in his shop.

[@AlexTheCarDoctor]

@@Mike__P double edged sword lol

[@antoniomarc7174]

Well hopefully 🤞 it’s a fix that doesn’t include a new engine…good work. Yikes 😳

[@SFCAMARO]

How much to fix it. ?

[@djadrian9318]

Do all the V6 Camaros have the dod for the fuel on demand system or active fuel management system how can I get away from that only with the four cylinder

[@MAD_BST]

Pretty much the same thing happened to my car bc someone cant do basic math. 7.600 push rod in an ls3 = no good. mushroomed lifter ruined the cam and lifter bore, wanted 10k to rebuild that engine, found a rebuilt engine for 5k and car STILL isnt together.

[@AlexTheCarDoctor]

Dang bro sorry to hear that

[@isnowyazn]

Update?

[@DIY-Mark-3]

Bad cylinder due to dark soothing color

[@MAD_BST]

if that car has an afm/dod delete someone did that shit wrong, @ 6:26 u can see the valley cover is NOT SMOOTH. thats ur first sign someone did NOT DO THE JOB RIGHT.

[@AlexTheCarDoctor]

They plug the oil ports,that was the first thing I thought too

[@leadfoot97]

GM was sued for the lifter issue with that start/stop tech.

[@user-zk8ox6qf9r]

Where’s the update ????👀👀

[@nykellesoutherland3214]

I’m saying

[@08turboSS]

Turning it all off wont solve the issue, you must swap lifters and cam.

[@AlexTheCarDoctor]

They did. Swapped Lifters and Cam and it still failed

[@qqq12qz]

@@AlexTheCarDoctor bought a car and it was a bit noisy(replaced yella terras because I heard they make noise with PRC rockers), but I had a second opinion and they think it's a lifter. Previous owner put in Lunati Link-bars. I'll be going with stock new ls7s. Check lifters before installs! If you google it, you will see that there is basically an industry wide failure due to manufacturing. We're seeing it everywhere.

[@Nodnarb69]

You didnt put the link in the description :(

[@AlexTheCarDoctor]

Dang my bad, what was it for. I can link it here.

[@Nodnarb69]

@@AlexTheCarDoctor its all good i found the video! Where is your shop located at?

[@Chiefgeargrinder]

Engine Parts probably made in China or the lowest bidder. Boeing is having similar quality control issues.

[@fkrr5]

China parts and UAW labor are a bad combo

[@atiashaunbaker3792]

Wow. A new engine ??? So it wasn't worth a teardown and replacing that faulty lifter ?? I don't trust GM products .. I've seen later model Cameros stuck on the side of the roads enough .. So a DOD delete / mod caused this???

[@AlexTheCarDoctor]

My guess what could happen maybe cheap oil or faulty/cheap lifters
