Ford will recall 90,736 vehicles as engine intake valves in the vehicles may break while driving, the National Highway Traffic Safety Administration (NHTSA) said on Saturday.
The recall impacts certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA said.
As part of the remedy, dealers will perform an engine cycle test and replace the engine as necessary, free of charge, the regulator said.

So a supplier was sent valves that were made with metal full of impurities then. I wonder how many valves fell into the combustion chamber and seized the engine while people were doing 60 mph on the highway?
Quality control is for shit these days.
and replace the engine as necessary,
Honestly, it kind of feels like the industry should have figured out how to make a gasoline engine by this point in the product’s lifecycle.

Ford says the intake valves in these engines were made from a special weight-saving alloy called Silchrome Lite. These valves must be carefully heat treated during manufacture because getting them too hot can make the alloy too hard and brittle, increasing the risk of cracking and sudden failure. The Silichrome Lite alloy has since been discontinued and replaced with a different alloy called Silchrome that is less prone to cracking and failure.
I guess it was due to a new material and that they were probably using it due to fuel efficiency requirements, so I guess it’s kind of a new environment.
That’s an interesting argument, I usually don’t think of valve stem weight when considering the weight of the vehicle.
It more likely related to the valve being able to move faster with less force. That then allows the engine to run more efficiently.
Probably not low-hanging fruit for weight reduction, but manufacturers have been reducing weight across-the-board for decades, so I expect that the biggest wins have probably been done a long time ago.
Saw a similar number a few weeks back and had to double check, different vehicles this time. Ford really hitting these back to back. So glad we bailed them out years ago.
Ford == Fix Or Repair Daily.
As the owner of a 2014 Ford, I had to factory recall five times in its life. I didn’t realize how that’s not the norm until a bunch of friends sat me down and explained.
Yeah, I haven’t been able to get through to my friend on that yet.
