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.
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.
