2.7L blown engine failure list . . 68 so far [Updated: December 13, 2022]

[DrBriGuy]

My
Engine was built nov 15 why don’t ford issue a recall so we can get our vehicles in instead of breaking down on the road and not only blowing the engine but destroying 2 turbos in the process. Seems it would be cheaper if they just issued the recall

Financially a full recall just doesn't make sense unless Ford already believes a huge percentage will fail.

By definition, there are 2 orders of magnitude difference at 1% replacement (fixing broken) vs. 100 % replacement (recall). This is just an example - no one knows the true failure percentage and we won't for a long time.

I'm going to use fictional numbers here so I don't get crucified - just an exercise. And if you don't like these back of the envelop exercises please just keep scrolling...

Let's assume 50,000 engines at a cost of $5K parts and labor (cost to Ford - not price to you - and just an estimate)

recall all: 50,000 x $5K = $250,000,000
fix 1% when they break: 500 x $5K = $2,500,000

Of course they have to value in lots of other stuff (value of human loss if a safety issue, reputation, loss of new customers, etc.).

Better question was asked earlier: would they just recall the valves? Probably not financially competitive with just replacing 1% of all engines, but maybe a good hedge for them. I don't know what those parts cost but assuming intake, 2 per cylinder, 12 overall and probably 2-3 hours of labor? Someone who has done this repair would have to comment if that's a reasonable estimate.

12 valves at $100 apiece = $1200
3 hours labor ($125 x 3 = $375)
$1575 per vehicle x 50,000 = $78,750,000

All numbers are just for perspective since so many people are clamoring for a recall. I think it all comes down to how much liability is on the road for Ford.

Do you think all the aa engines will be replaced bye a recall are all aa engines no good

Is this what is meant by an AA engine?

Yes

So I did a little research when I got some time today. Here's some of what I cyphered:

Complete cyl head assy: ML3Z-6049-K LH, ML3Z-6049-J RH. no need to compare w/F150, you can see from the prefix those are Bronco only

Ex valve: JT4Z-6505-A
Valve spring: FT4Z-6513-A
Keeper: FT4Z-6518-A
Lock: FT4Z-6514-A
Rocker: FT4Z-6564-C
Lifter: BR3Z-6500-A

Got all those #s from repair link, thats when it got interesting...no intake valve listed! So I called my local parts dept that I buy from regularly. The guy I got i know I've talked to before, and is knowledgeable. Gave him the last 8 and asked for intake valve part #. 1st he asked me "this isn't one of those 2.7s that blew up is it?" Which I asked him "have u guys seen any of these?" He said "WE haven't, but I've heard about it" anyhow, his system didn't show a part # for an intake valve either...just an engineering #. The engineering # doesn't lead anywhere, but if he crosses it manually it comes back as FT4Z-6507-A.

The only PN I had him cross over to F150 was the exhaust valve, and they are the same, so the $64k question? Are the failed 2.7 valves all intakes? Don't know we will ever get a clear answer to that, but it sounds like they used a different intake valve and there was a manufacturing issue...heat treat etc. The service PN may be on hold till they decide how to address the issue...revert to previous parts, or trust the new intake valve manufacturer to fix the issue.

Wow yeah very interesting does really make you think there has been a change for that part in some way. Nice detective work!

Someone could start a Google spreadsheet for this forum where we add a row for each user, their engine build date, and mileage. If we can get people to occasionally update their mileage (I.e every 1000 miles) That may help us eventually see a failure rate.

I would do this, but I’m not sure how to host the Google spreadsheet publicly.

Yes

So, the thought now is that engine version AB will have been fixed? Just my two cents. If it is valve train related, it would seem to me that Ford would recall the engine to the shop to fix the problem. I know, this has been said before but honestly, for this kind of failure, a blown engine is not the only concern for Bronco owners. Do you know how cold it gets in Alberta Canada where I live? We have already had temperatures well into the negative 30 C range. (that's -22F). Two winters ago, traffic was stopped on the Trans Canada Highway 1 for 18 hours in the middle of a blizzard. Imagine being in a Bronco for 18 hours, without heat. Yikes!

I am not sure nor is anyone else at this time. And is the AB the 2022 model year which mine is? Meaning the 2022 year gets a AB run motor but its just the AA only the AB classifies it as a 22?

From your lips to Ford's ears

Same I got 615 on mine lol took delivery dec 17 with 3 miles on it

Mine's a MY22 that's an AB and a date of December 20, 2021. Picked it up this weekend and have only 350 miles on it.

As an MBA- taking into consideration this is based of mental math. You're 100% right. There's a reason why people make 6-7 figures a year doing exactly what you just did- but with highly accurate forecasting and research data.

ok, so if Ford is unlikely to pony up lol, for a recall, it seems to me there is no way in hell they would release any data/statements about engine failures.
That would leave us twisting in the wind indefinitely, adding our failed build numbers for little benefit.
