I'm assuming these white smoke and Coolant loss events are secondary to the initial failure. Valve drops, chaos erupts and a hole is punched in a cylinder wall or water jacket. I've personally seen engines with a hole in the block still run...very loudly. And it appears some people's engines...
I agree...and we've already shown failures past that date. This could be as simple as a wide band O2 sensor part change and a small tweak in the PCM Is needed to read correctly...if you have the problem.
Also, I agree with @flip , don't run to the dealer with this list. Just be aware your not...
Almost all the ones that mention Ranger and Bronco are on the 2.3L or non-engine related. The one I'm referring to is Bronco 2.7L and requires reprogramming the ECU and/or replacing the upstream O2 sensors. There are a few other non-engine related TSBs that everyone should read and check their...
I poured over these last night. Only interesting one was a software update for a lean condition. But engines have failed in Broncos built after the date listed. Could still be a problem though.
If the redesign story is true, I'd suspect a SSM will be posted in the near future.
However, I'd say redesign may mean anything...could just mean a different specific component needs to be sourced...such as an intake valve.
I wish we had this data on all 26. I've DM'd a few with no response. The next best data point is model. I don't think it matters, but more data is best.
"Winch out services: includes pulling a vehicle within 100 feet of a paved or county maintained road. No recoveries."
Don't think Ford is hauling you off a trail.
I guess it's not really who pays for it rather than the headaches involved...
Kudos to you making a MFG pay for a tow that took 3 days to happen because you were at 13K feet.
My Bronco is my wife's daily driver. I haven't told her about any of this...whats worse, her freaking about about every weird sound or acting normal when a vehicle shuts down? Struggle with that like I am...
We'll get through this. It isn't ideal and we all know the first year blues and...
Not sure if we know that.
Theory, or at least mine based on what @flip said, is a valve retainer or stem is failing, dropping the entire valve into the cylinder and boom, it's over. That then causes timing chain failure and thus multiple cylinder valve failures on all cylinders on that bank...
