It’s the gift that just keeps giving the whole year through.

I just want to know if the valve failure is occurring on the same cylinder every time.

Absent any causation info from Ford, I guess idle speculation is appropriate.

Remember spring & much of summer when the 2.7 was "constrained"? The forum was agast that Ford had not anticipated its popularity in the order logs. Maybe it was a different problem entirely...maybe significant numbers of 2.7s were scrapped coming off the Lima line? For whatever reason.

Ford kinda showed their cards with MIC 1.0 - with glaringly obvious flaws they kept production humming for months. Even shipped many before opening dirt mountain.

Perhaps the MIC & 2.7 are cuzzins? :)

No, One tenth of 1 percent! In six sigma terms 0.1 Way too high!!
Their math also doesn’t account for the fact that there are probably way more nonB6G members hitting this — so even in that optimistic 24,000 2.7L delivered and 23 B6G member failures reported, it’s a minimum failure rate of ~1/1000 which is wayyyyy too high. If there are another 120 or so nonB6G failures out there, that’s 1/200 chance of getting a dud. I would not take those odds.

On another note, is there anyone that has an engine within these build dates & mileage that could get their probed and see if there is any early signs of cracks or possible damage

Real shame Ford isn’t working with Bronco owners to try and diagnose this — you could easily get a service department to scope the cylinders if Ford was paying an hour or two labor rate to do so.

No 22/24000 = 0.00091 = one hundredth
edit: I’m confused I’m just leaving this here LOL

1/2 is 0.5 = one half = 50%
1/10 is 0.1 = one tenth = 10%
1/100 is 0.01 = 1%
1/1000 is 0.001 = 0.1%
1/10000 is 0.0001 = 0.01%

its roughly 1/1000 at this rate by those rough estimates because it’s ~24/24000 which is 1/1000 or 0.1%

As part of the replacement, I would ask them to inspect the oxygen sensors and the face of the catalytic converter. It there is damage to either this will cause more problems down the road. We should put together a list of things that shall be replaced and things that should be looked at. Imagine a chunk of valve or massive oil deposits on your converter.🤮
