Are Cylinder Deactivation deletes a thing yet?

[Murrk847]

Are there kits to physically remove the '21+ Cylinder deactivation yet? Looks like it would all be work under the valve cover but I am not a mechanic. From what I read there are oil solenoids that deactivate specialized rockers? So maybe would be a rocker swap and capping off/deactivating the oil solenoids? Not sure if the oil solenoids are something you can simply pull out. I am just spit-balling here.

I haven't seen any issues with CD but time will tell. Has not caused me any issues but might be something to consider when my warranty expires if it starts grenading engines.

I haven't seen a "kit" to do that (yet). Aside from the couple of ways to temporarily turn it off (ex. use tow/haul drive mode) there are few performance programmers now that can disable it in the tune is all.

Looks like it would all be work under the valve cover but I am not a mechanic.

And there is probably some software involved to know when to activate/deactivate it.

Yep, pretty much, sounds so simple..... here is a video that helps explain the system Ford 5.0 Cylinder Deactivation Explained

So maybe would be a rocker swap and capping off/deactivating the oil solenoids?

From the pictures I've seen, that seems about it, plus the programming so it knows it's not there and set off a code or something.

Spit-balling is what festers ideas

Livernois tune solves the issue. I’ve been meaning to do it for awhile now but $700 is a hard pill to freaking swallow.

Yes, get a tune.
I had the Livernois done with CD gone, plus the added bonus of smoother transmission shifting and an uptick on power.

Why would you want to? I have yet to hear about a problem with it.

I dont want to, but every AFM engine has fallen at its face. The chances of this one being bullet proof are slim to none.

My uncle's Chevy engine destroyed itself with cylinder deactivation gone wrong.
It isn't without issues across all brands, but such events are a rare thing.
Have not seen any posts online of Ford issues with it. Everyone comes to the internet to complain so I would expect several posts if it was really an issue.

Fords system shares absolutely zero in design with its pushrod competitors. This is like saying because your neighbors CertainTeed roof failed your GAF roof will fail lol. There is no basis for it.

I'm surprised to hear they are still using pushrods at all! Wow. That's ancient tech.

Take a close look at it for yourself!

I'm NOT a mechanic so I'm seeing the same thing YOU are seeing here... A bunch of engine parts that mean very little too me.

But... I DID do the "research" before I dumped my hard-earned money into an “experiment”.
I wish I could say the same about the “jab”!

And I “learned” that Ford’s amazing engineers not only “took a page” from the GM “cylinder deactivation disaster”… but they ripped it up, burned it, pissed on the ashes and started over from scratch.

And I ALSO learned that they did the same thing with their Starters for Auto Stop Start.

That horror show you see in the photos I posted in the link are from poor Canadian Q.C. while manufacturing my Valves. NOT from “poor engineering” from Ford.

I NEVER disable “A.S.S.” and I DON’T run in modes that disable cylinder deactivation (you CAN) and I have made it a point to beat the living shit out of my GEN14 5.0 at every opportunity just to make sure it’s 100% before my Warranty is up.

IT IS!

Don't worry... you're "all good"! Just enjoy your new 5.0 and be careful! She bites back!

Just because it is different does not mean it's better. It has yet to prove itself long term. If my neighbor had a GM roof and it failed I am not going to automatically assume my new Ford roof is fail proof just because the shingles point a different direction.

All I am asking is if there is an option to consider in the future. If ford offered a "CD delete" from the factory, 99% of the people in this sub would take that option, but since you cant everyone is quick to cope with it and defend its design when they have no idea until majority of 21/22's starting hitting high mileage.

CD helps meet federal emission and mileage standards. You know... so Ford can continue offering the V-8's.

Yes, people don’t realize how many 5.0 F-150’s Ford sells. As of 2024 the market share of the 5.0 is going to spike up to 35-40% with Fords new product structure which now mandates the V8 for towing pack in low trims, and the 5.0 is also now the premium engine in STX, as well as being standard on Tremor. Even at the old 25% figures that’s about 200,000 5.0 engines.

To put that into perspective Toyotas total sales for all tundras were 112,000 for 2023. That means 2X F-150 V8 were sold compared to all Tundras sold in the US. That’s a huge effect on corporates average. Mustang sales are normally 30-50k, so the F-150 engine has way more bearing. CD on 200,000 engines helps. And now that’s going to be more like 300,000-400,000 engines. Ford is pushing more V8 (idk why with the way of things) but they are. I think the ultimate solution is offering an optional hybrid pack for the 5.0, as many of us V8 loyalists will buy that before a turbocharged smaller engine.

Im not afraid of the CD, it’s a well thought out system that has been used on several Ford OHC motors for the last 5-7 years. Issues are not reported in the European market where it’s been used for many miles now.

the pisser is it is no longer an option on the King Ranch for 2024

CD deactivation was the main reason for me purchasing a tune.
Added performance and transmission behaviour took a close second.

One reason was because it's an unproven system, although in theory I do believe in it and the second reason was because I have aftermarket exhaust and constantly having to slip into sport or tow/haul was getting old. I also didn't enjoy the behaviour of both modes for everyday driving.

Now, I don't need to constantly flip my drive mode when I turn on the truck and a big bonus of the truck transmission shifting wayyy better plus there's definitely a noticeable improvement on power.
