Toyota warranty issues have revealed at least two engine failures in the GR86 sports car, which is related to the Subaru BRZ and is powered by the Subaru FA24D four-cylinder engine. Owners have reported potential problems with the car’s lubricating system, and at least one has opted to investigate more.
Brian Armstrong, the owner of a 2022 Subaru BRZ, claims to know three different people who have blown their cars’ FA24 engines on track, which prompted him to conduct this testing.
Armstrong fitted up two oil pressure sensors with data-logging capability to his and another’s vehicle in separate positions on the engine to try to pinpoint a potential problem. This data can be overlaid with engine RPM and other information when connected to the vehicle’s CAN bus.
