Jaguar Land Rover (JLR) approve the use of thread inserts on all engines except V6 Cologne, on all areas of the engine except power conversion elements, for example, pistons, crankshafts, con-rods etc.
Where applicable please use this method of repair. Do not replace the affected component, for example, the complete engine or cylinder head.
Extra care should be taken, especially during the tapping phase of the repair. This is critical to make sure the repair is correct.
