Timing Chain Tensioners:
Early AJ26 V8s are known for plastic timing chain tensioners that can degrade and fail, leading to catastrophic engine damage. This is a critical item to inspect/address.
Head Gaskets:
Potential for head gasket leaks, particularly on the 4.0L engine. Symptoms include coolant loss or white smoke.
Nikasil Cylinder Liners:
Early AJ26 engines used Nikasil liners, which could be susceptible to wear from high-sulfur fuels. Later versions and remedies exist.
Transmission Issues:
ZF 5HP24 transmissions can exhibit harsh shifting or failure to engage if not properly maintained. Regular fluid and filter changes are crucial.
Dsc Module:
Dynamic Stability Control (DSC) module failures can occur, affecting traction control and ABS operation.
Heritage Summary:
Jaguar has a long-standing reputation for luxury, performance, and elegant design in the automotive world.
