Oil Leaks:

Potential for oil leaks from valve cover gaskets, oil pan gasket, and oil cooler 'octopus hose'.

Nikasil Liner Wear:

Early AJ-V8 engines used Nikasil cylinder liners, which could be susceptible to wear from high sulfur content fuel. Later models switched to aluminum liners with plasma coating.

Automatic Transmission Issues:

ZF 5HP24 can experience harsh shifting or solenoid failures; regular fluid changes are crucial.

Suspension Wear:

Control arm bushings, ball joints, and shock absorbers are common wear items due to the vehicle's weight and performance.
