Need a new engine
My run of good luck with F150s with the 5.0 has finally run out. I never had any problems with my 2014 or 2016 but my 2018 is a different story. It just quit working on Saturday. I had it towed to the dealership where I bought and today when I went to see what was going on with it they told me that I needed a new engine. They figure that It either dropped a valve or snapped a connecting rod. The technician that took a look at it showed me the spark plug for it and the bottom of it was completely flattened.

Another guy on here had this happen to him a couple of weeks ago....dropped a valve and seized the motor.

Must be more than a few rolling off the line with weak valves (I'll be honest...the idea of a dropped valve is pretty ridiculous in a modern low-mileage motor)....kinda like the LS7...
Anyone know if the valves on 5.0 are sodium filled? I thought I read somewhere that they were (may have just been the stangs).

Yet another 2018 horror story!
The more stories i hear like this the less apt i am to buy another new F150.
What the hell is Ford using to make these new engines out of? Used chewing gum?
Where's the quality control?
A dropped valve? Far as i can tell, the only way that could happen is a broken spring, retainer failed, the valve itself failed or over revving.
A snapped connecting rod? Are they now using compressed powder connecting rods in the 5.0s instead of solid metal?

I had a 2015 that had to have the transmission replaced after 300 miles. I told the dealer I wanted a new truck. Filed the paperwork through ford and they bought it back from me. Took a few months but worth a shot if that’s a route you want to go.

Rev- limiters only prevent over revs on upshifts. A hiccup on downshifting or a mis-shift can over rev the engine easy. My 6R80 has downshifted to 2nd before when I was at the top of 3rd. My log showed I hit 8257RPM.
