Other Engine Info
LPG conversion can be accomplished on the engine.
Problems:
Leakage in brake lines
Hydraulic brake systems can develop leaks in the brake lines, which reduces the pressure needed to stop the vehicle effectively.
Brake fluid contamination
Over time, the brake fluid can become contaminated with moisture or debris, leading to reduced braking performance.
Brake pad wear
Regular wear and tear can cause brake pads to thin out, reducing their effectiveness and necessitating replacement.
Warped brake rotors
Heat generated from braking can cause the rotors to warp, leading to vibrations and reduced braking efficiency.
Overheating engine
V-shaped engines, especially older models, can suffer from overheating issues due to clogged radiators, faulty thermostats, or failing water pumps.
Oil leaks
V8 engines, like the one in the GMC Sierra, can develop oil leaks around the valve covers, oil pan, or rear main seal.
Ignition system problems
Older V8 engines can experience issues with the distributor, spark plugs, or ignition coils, leading to misfires or poor performance.
Fuel system issues
Converting the engine to run on LPG can sometimes cause fuel delivery problems if not done correctly, affecting engine performance.
Exhaust manifold cracks
V8 engines are prone to developing cracks in the exhaust manifold, leading to exhaust leaks and reduced performance.
Transmission slippage
Older vehicles like the 1993 GMC Sierra can suffer from transmission issues, including slippage and hard shifting, especially if the transmission fluid is not regularly changed.
Corrosion
As the vehicle ages, corrosion can affect various components, including the brake lines, fuel lines, and body panels, leading to further mechanical issues.

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.
