Problems:
Cooling system issues
V12 engines generate a lot of heat, and the Jaguar XJS is known for having a cooling system that can struggle to keep up, leading to overheating problems.
Fuel injection problems
The 1986 Jaguar XJS uses a complex fuel injection system that can develop issues, such as clogged injectors or failing sensors, leading to poor performance and fuel economy.
Electrical problems
The electrical systems in older Jaguar models, including the 1986 XJS, are known to be unreliable, with common issues including failing sensors, wiring problems, and faulty ignition components.
Oil leaks
V12 engines have a large number of gaskets and seals that can wear out over time, leading to oil leaks that can cause engine damage if not addressed.
Timing chain wear
The timing chain in the V12 engine can stretch or wear out, leading to poor engine timing and potential engine damage if not replaced in a timely manner.
Vacuum leaks
The complex vacuum systems in the Jaguar XJS can develop leaks, leading to rough idling and poor engine performance.
Exhaust manifold cracks
The exhaust manifolds on the V12 engine can develop cracks due to the high heat, leading to exhaust leaks and reduced engine efficiency.
