New Motor

[Jeff Ross]

So I was happily driving along in my 2024 Ecoboost Premium with just under 5K. All of sudden it started misfiring and got engine light. Bummer!
Turns out, I am told, a part of the #4 spark plug broke off and trashed the cylinder and turbo.
Got it back with new (“single use”) long block and turbo.
I’ve put about 100 miles on it, and noticed hood flutter and on a close look the hood is a bit out of alignment. I was so focused on looking for dents and paint chips that I missed it. Called service and they said they will send a tech to my house to fix it and also do the BCM recall. So that’s cool.
Anyway it took 30 days to get the car back, but seat of pants says it’s running just like it did before. Of course for 30 daze I had to answer everybody the question “where is your Mustang?” - very embarrassing. I’m 72 never had a motor let loose on me - I guess my luck ran out - hope I have better luck with this motor.
My question to you all - what does “single use” long block and turbo mean?
Thanks!

Hm , you should have lemoned it. Ford would have either offered you money (few thousands) to keep your car and still try to fix it or a full refund (buyback). It happened to me with my 23 EB. It ended up as a lemon. Then got the GT. Much happier.

"What does “single use” long block and turbo mean". Basically you got a new fully factory assembled EcoBoost engine not like a separate 4 cylinder engine, separate turbo and assembly done at dealer. That is my understanding. But I might be wrong

I think single use means the bores are not machinable due to the coating that's used. I may be wrong.
I'm not familiar with lemon laws, but common sense tells me they would not cover the failure of a third party component such as a spark plug.
Which, BTW, is something I have never seen. Although I have seen a plugs threads strip and blow it into the hood.

Fords ‘97 - ‘03 5.4 Triton V8?

Fords ‘97 - ‘03 5.4 Triton V8?

4.6L V8s of the same era were also equipped with the ejecto-spark plug feature. Good times for all.

For the OP's sake, I'm hoping this replacement EcoBoost powerplant will alleviate any future 'EcoBoom' headaches and provide many miles worth of enjoyment.

No, Pommie stuff. I was in the trade in the 60's and 70's

I'm surprised this is common. What was the cause? Any particular brand?

Never seen a plug break off. Likely already compromised prior to installation from mishandling. Sucks man, but sorry to hear.

Having a spark plug break and destroy an engine is unusual

Having an ecoboost fail with low mileage and normal use is not

IMHO they are pure garbage and most dealer techs would agree with me.

Longevity and ecoboost are never said in the same sentence

The ecoboost in the mustang is a modernized open deck version of the 2.3 engine ford and mazda developed that they put in the mazda speed 3. Back then it what gave mazda the zoom zoom boom stereo type.

I had sparkplugs rattling in my 2.3 focus rs. Very wierd. Removed plugs and 2 of them rattled. The porcelain on top slid up and down. It was a well known performance brand but not ngk.

Not sure if focus st has the same engine as mustang, but i bought one new and sold it with 215,000 miles on it. Pretty sure the new owner has it close to 300k. No engine work, valve cleaning, etc. Original turbo. There are success stories.

Actually, the Ecoboost is more reliable than the Coyote according to this source (skip to 5:28):

 

[Neggytive]

again, ask any Ford dealer tech how many ecoboosts he or she sees with major issues vs a Coyote

no shot. go to any ecoboost forum or subreddit, a good 1/4 of the posts are just asking about issues, problems, or warranties.

Shit motors

Lo

Lol you think a 4 cylinder pushing 18-20 pounds of boost is more reliable than the most bullet proof v8 on the market?. You do realize ford tested the coyote at 800 hp and certified that it met its 100k miles tests. You can literally rag on the coyote every day and it will be fine as long as you check the oil every 1-2k miles and top it off.
