Bronco 2.7L Failures

Recommended Posts

What's the scoop on the number of failed 2.7L being reported on B6G?  Anyone here have some insight?

The first I’ve heard about this, but the 2.7 has been around for quite some time and by all accounts a reliable motor, so that would be surprising.

Over 25 documented cases.  Seems to be in the valve train, with possibility of a keeper or stem failing.

Sounds like a bad batch of motors, as I haven’t heard of any major changes to this motor within the last few years, that would have resulted in some new components.

Based on some research of others on the board it appears some of the valvetrain components and oil pan are specifically different than the F150 2.7L.  I have not independently verified that.

In comparison to how many of these engines they make, I'd guess that this falls well under 1% failure rate. I think it's the hyperbole associated with BG6 that this has gotten legs. I hear it's a valve issue. Maybe a bad batch came out? Ford obviously is aware of these and until we get a TSB or recall, we'll have no idea how many engines are effected.

Agree.  Just interested if anyone in this community had some info to share.  As a 2.7L Bronco owner, it be nice to know if I'm on borrowed time.

I do not know the number of failed engines, but Ford estimates the engine defect affects 25, 538 Bronco’s:  https://fordauthority.com/2022/06/ford-bronco-2-7l-v6-ecoboost-engine-failures-explained-exclusive/
