Most common problems:

Brake fluid leaks

Hydraulic brake systems are prone to leaks which can compromise braking performance and safety.

Brake fade

Overheating of the brake system can lead to reduced braking efficiency, especially during prolonged or heavy braking.

Brake pedal sponginess

Air in the hydraulic brake lines can cause the brake pedal to feel spongy and reduce braking effectiveness.

Engine misfires

V8 engines, especially older models, can experience misfires due to ignition system issues or fuel delivery problems.

Oil leaks

V-shaped engines like the V8 can develop oil leaks from gaskets, seals, or the oil pan over time.

Cooling system issues

Older vehicles can suffer from clogged radiators, failing water pumps, or thermostat problems, leading to engine overheating.

Timing chain/belt wear

High mileage engines may experience wear or stretching of the timing chain or belt, affecting engine performance and timing.

Fuel system problems

Given the age of the vehicle, fuel injectors or the fuel pump may start to fail, leading to poor fuel delivery and engine performance issues.

Exhaust manifold cracks

V8 engines can develop cracks in the exhaust manifold, leading to exhaust leaks and increased engine noise.

Oxygen sensor failure

Older engines may have failing oxygen sensors, which can affect fuel mixture and emissions.

Lpg conversion issues

If the engine has been converted to LPG, there may be additional complications such as fuel delivery problems, tuning issues, or valve seat wear.
