Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers, leading to decreased braking efficiency.
Brake fade
Overheating of the brake components can cause the brakes to lose effectiveness temporarily.
Worn brake pads
Brake pads wear out over time and need to be replaced to maintain proper braking performance.
Engine misfire
V-shaped engines with 8 cylinders can experience misfires due to issues like faulty spark plugs, ignition coils, or fuel injectors.
Oil leaks
V8 engines, especially older ones, can have oil leaks from the valve cover gaskets, oil pan, or rear main seal.
Overheating
The cooling system may become less effective over time, leading to engine overheating, especially in older models like the 1991 CHEVROLET GMT-400.
Lpg conversion issues
Converting the engine to run on LPG can introduce new problems such as fuel delivery issues or compatibility with existing engine components.
Timing chain/belt wear
Over time, the timing chain or belt can wear out, leading to potential engine timing issues.
Vacuum leaks
Older engines can develop vacuum leaks in hoses or gaskets, causing rough idle or poor performance.
Fuel pump failure
The fuel pump can wear out and fail, leading to engine starting issues or stalling.
Intake manifold gasket failure
V8 engines are prone to intake manifold gasket failures, leading to coolant leaks or vacuum leaks.

Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, calipers, or master cylinder, leading to reduced braking performance.
Worn brake pads or rotors
Over time, brake pads and rotors wear down and need to be replaced to maintain effective braking.
Air in brake lines
Air bubbles in the hydraulic brake lines can cause a spongy brake pedal and reduce braking efficiency.
Vibration during braking
Warped rotors or uneven pad wear can cause vibrations or pulsations when braking.
Engine overheating
V-Shaped engines, especially older models, can suffer from overheating due to issues like a clogged radiator, failing water pump, or a malfunctioning thermostat.
Oil leaks
V8 engines are prone to oil leaks from valve cover gaskets, oil pan gaskets, and rear main seals.
Fuel system issues
Older engines, especially those converted to LPG, can face fuel delivery problems such as clogged fuel injectors or failing fuel pumps.
Ignition system failures
Problems with the distributor, spark plugs, or ignition coils can cause misfires and poor engine performance.
Exhaust manifold cracks
V8 engines can develop cracks in the exhaust manifold, leading to exhaust leaks and increased engine noise.
Timing chain/belt wear
Over time, the timing chain or belt can wear out, leading to poor engine performance or even catastrophic engine failure if it breaks.
Poor fuel economy
Older V8 engines, particularly those converted to LPG, may suffer from reduced fuel efficiency due to wear and tear or suboptimal tuning.
Emissions issues
Older vehicles may struggle to meet modern emissions standards, especially if the engine is not properly maintained.
Electrical problems
Aging wiring and connectors can lead to various electrical issues, such as starting problems or intermittent faults.
