An external oil leak may lead to an engine bay fire
Several thousand Land Rover and Jaguar models have been recalled in the United States due to a potential oil leak. Lr039621
A recall notice published by the National Highway Traffic Safety Administration (NHTSA) reveals that a small number of Jaguar Land Rover models fitted with the British carmaker’s AJ20-P6 3.0-liter six-cylinder engine may have a cam carrier oil gallery that hasn’t been fully drilled.
As such, the oil channel could be blocked, potentially leading to the accumulation of oil against the pressure control valve’s rubber membrane. The problem could result in an external oil leak or trigger increased oil carryover into the air intake system. An external oil leak may lead to an engine bay fire.

The car manufacturer was first alerted to a potential problem on November 23, 2022 after it received a report from Ryobi Aluminium Casting in the UK that an oil channel had not been correctly drilled on a small number of engine cam carriers that it manufactured and supplied to Jaguar Land Rover. A stop-shipment was immediately issued for vehicles with the affected engine and the carmaker instructed markets to hold affected vehicles and inspect them for the problem.
The recall impacts a total of 6,644 vehicles from the Land Rover family. These consist of Range Rover models built between August 24, 2022 and November 30, 2022, Range Rover Sport models built between October 12, 2022 and November 28, 2022, Range Rover Velar models built from October 26, 2022 and December 5, 2022, Land Rover Discovery models made from October 14, 2022 and November 30, 2022, and Land Rover Defender models produced from October 13, 2022 and December 1, 2022.
In addition, 229 examples of the Jaguar F-Pace built from October 27, 2022 to November 24, 2022 are involved in the recall.
Lr036127 Owners of impacted models will be instructed around March 31 to bring their vehicle to a JLR dealership where a correctly machined component will be fitted if an incorrectly machined cam carrier is found.
