We have a 2.7 in my wife's F-150, I also frequent the F-150 forums. I can count the number of dropped valves on the F-150 reported on the fingers of one foot.Isn’t the 2.3 to 2.7 ratio something like 1:5? I would expect the 2.7 to have a higher reported failure number due to the overall imbalance.
Something is not right (statistically speaking) with the 2.7 in the Bronco.
