My 2019 let go with low mileage as well (possibly the one you are referencing). "Valvetrain failure" was all the info I ever got. It does seem like there is some component level issue - perhaps a metallurgy issue? that is causing some sort of valve failure and eating the engines. I suppose the real question is... Is this a bad component in some small percentage of production that always fails early, or is it something affecting a much higher percentage of production that can happen at any time and just happens early for some of us? Seems like the 2019+ engines are a lot better than earlier ones....except for this issue...whatever it is...
What was your build date?

Damn .
So sorry OP.

So much for the new and improved motor .
Maybe it’s another valve train issue ?

Anybody thinking of “upgrading “ because of the new motor from a pre 19 better think again .(Because of 3 engines?):cwl:

Worst case scenario if your pre 19 stock motor fails send it off to be built by a reputable shop to address the all the sub par stuff . Would still be cheaper than trading . Lol
Me personally I am “stock piling” voodoo motors(Instead of toilet paper ) - you will be surprised how affordable a short block build can be . Used heads are also fairly cheap so you can “upgrade “ the valve train too .
I looked at the “Gen 2 “ heads (same as they have on the predator ) but may be better off avoiding them (too much $$$ anyway ).

Is this the same engine that is in the new GT500 cars, but supercharged?

Seems to be a issue with a build part on the engine. As some has said, bad valves. A bad batch that was used in the engines could be this issue. Will be hard to see how many engines were built with these bad parts.

Mine was May 2019. I wish we knew when the bad batch of parts was introduced into the assembly process.

Mine was May, and I've been driving the hell out of it since day one.

I took delivery on June 11th and I'm pushing 12,000 miles. No oil consumption and two oil changes.


Mine is Ruby as well, but I ripped the stripes off.



OP, did you add that blue washer cap, or did they change it? Same with the air filter?

Shit, mine too. I’m pushing 2500 miles. Fingers crossed
You'd have to know the build date on the engine, not the car. ;)

No, I think you need to know which lots of valves and their dates were used on the builds. Ford should be able to track the lot numbers of the valves they got from the supplier and which engines they were used in. I expect more of this type of failure to happen.
