Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers, leading to decreased braking efficiency.
Brake master cylinder failure
The master cylinder can wear out over time, causing a spongy brake pedal or complete brake failure.
Brake caliper issues
Calipers can seize or leak, affecting braking performance and causing uneven brake pad wear.
Brake pad and rotor wear
Regular wear and tear can cause brake pads and rotors to become worn, leading to decreased braking ability and potential safety hazards.
Misfiring cylinders
V8 engines can experience misfires due to ignition system problems, fuel delivery issues, or mechanical faults.
Oil leaks
Older V8 engines, like the one in the 1990 GMC Sierra, are prone to oil leaks from gaskets, seals, and valve covers.
Overheating
V-shaped engines can suffer from cooling system problems, such as radiator clogs, thermostat failures, or water pump issues, leading to overheating.
Timing chain or belt wear
Over time, the timing components can wear out, potentially leading to engine performance issues or catastrophic engine damage if they fail.
Fuel system problems
Issues with the fuel injectors, fuel pump, or fuel filter can cause poor engine performance, stalling, or starting difficulties.
Vacuum leaks
Vacuum leaks can lead to rough idling, poor acceleration, and reduced fuel efficiency in V8 engines.
Exhaust manifold cracks
V8 engines are prone to developing cracks in the exhaust manifolds, leading to exhaust leaks and increased engine noise.
Carbon buildup
Older engines can accumulate carbon deposits on valves, pistons, and combustion chambers, leading to reduced performance and efficiency.

Other Engine Info
LPG conversion can be accomplished on the engine.
Problems:
Brake fluid leaks
Hydraulic brake systems rely on brake fluid, and leaks can cause a loss of braking power.
Brake fade
Overheating of brake components can reduce braking effectiveness.
Brake pedal feels spongy
Air in the brake lines can cause a spongy brake pedal feel.
Vibration or pulsation during braking
Warped brake rotors can cause vibrations or pulsations when braking.
Engine misfires
Worn spark plugs, faulty ignition coils, or fuel delivery issues can cause the V8 engine to misfire.
Excessive oil consumption
Worn piston rings or valve seals can lead to higher oil consumption.
Overheating
A malfunctioning thermostat, radiator issues, or coolant leaks can cause the engine to overheat.
Timing chain/belt issues
Worn or broken timing chains/belts can lead to engine performance problems or failure.
Fuel system issues
Problems with the fuel pump, fuel injectors, or fuel filter can lead to poor engine performance.
Lpg conversion complications
Improperly installed or maintained LPG systems can cause performance and reliability issues.
Transmission problems
Issues with the transmission, such as hard shifting or slipping gears, can affect overall vehicle performance.
Rust and corrosion
Given the vehicle's age, rust and corrosion can be prevalent, especially in the brake lines and body panels.
