Bronco 2.7 blown engine

[navi]

Supposebly a bad batch of valves from an outside vendor but ford is being a bunch of dick bags and not saying anything

How could it be a bad batch of valves when the blown engines were built over a 4 month period?

I’m just saying what was posted on hear bye a ford insider that all the blown motors have bad valves brittle and the engine is sucking them in

personally have not seen any blow-ups with this high a date, but many we don't know yet

range is about 160 - 216 . . . far as I've seen

Ok thank you for the information...hopefully they resolved the issue and was only an isolated issue with a small build range!!

link you have?

Why not just do it via Forscan? More versatile and cheaper.

Or just unplug from the negative terminal

The 2.7 in my 2016 f-150 blew with less than 30k miles. It took my local dealership 2 months to swap out the engine. Once I started looking into it I realized it's a huge problem with that motor. I'm surprised they still use it and there hasn't been a class action lawsuit filed.

Well good news for you then! It's not the same motor.

There is a distinct possibility that we are reaching an erroneous conclusion regarding the valves being defective given the range of failed motor dates. I want to see spark plugs, because I am suspecting that these failures are occurring typically in cruise or light loading situations where the engine is under boost, where detonation could easily destroy a rod bearing and result in piston to valve contact. If the OP has his Fordpass app he might be able to see some of the error messages from the engine.

Are you suggesting we avoid cruise control? I know from experience it apparently lowers mpg through the mountains

They issued the TSB in January 2018, a long ass time after the issue was well known. The TSB procedure was to compression test every affected motor: if it passed, you got an updated gasket. If it failed, you got a new small block. I’m well versed in the RS issues man, I’ve had a 2017 RS since new. My point was that Ford is incredibly slow when it comes to doing the right thing on engine failures like this.

Sounds like the time everyone knew BMW designed their E90 M3 rod bearings wrong and they refused to publicly acknowledge it even after a lawsuit and then when your engine blew up just driving around town BMW would courteously offer you the option of installing a new motor for $24,000. Ask me how I know.

Sorry to OP. Winning engine lotteries sucks.

That is not entirely true-- yes there were some failures with the 2.7 but over all the engine ha been quite reliable. I also experience a failure on the 2016 F-150 which was note d in Ford TSB 17-0007. This was a limited number of 2.7's built from 4/1/16 until 1/1/2017. The other other issue with the 2.7 which was far more common was the leaking oil pan. Over all the 2.7 has been quite reliable.

Worst, it wasn't the first "S" variant of a BMW engine to have substandard rod bearings...
