Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or wheel cylinders, leading to reduced braking efficiency.
Brake pedal feels spongy
Air in the hydraulic brake lines can cause a spongy or soft brake pedal, reducing braking performance.
Master cylinder failure
The master cylinder can wear out over time, leading to brake fluid leaks and compromised braking power.
Warped brake rotors
Continuous use and heat can cause brake rotors to warp, resulting in vibrations or pulsations when braking.
Engine overheating
In-line engines, particularly older models like the 4ZE1, can experience cooling system issues that lead to overheating.
Head gasket failure
The 4ZE1 engine is prone to head gasket issues, which can result in coolant leaks, engine overheating, and loss of compression.
Timing belt wear
The 4ZE1 engine uses a timing belt, which can wear out or break, causing engine misfire or severe engine damage.
Valve cover gasket leaks
The valve cover gasket can deteriorate over time, leading to oil leaks that can cause engine performance issues.
Fuel injector problems
Fuel injectors can become clogged or fail, leading to poor engine performance and reduced fuel efficiency.
Egr valve issues
The Exhaust Gas Recirculation (EGR) valve can get clogged or malfunction, causing rough idle or engine stalling.
Ignition system problems
Older ignition components like spark plugs, ignition coils, and distributors can fail, leading to misfires and poor engine performance.

Problems:
Brake fluid leak
Hydraulic brake systems are prone to leaks due to worn seals or damaged brake lines.
Spongy brake pedal
Air in the hydraulic lines can cause a loss of pressure and a spongy brake feel.
Warped brake rotors
Excessive heat and wear can cause the brake rotors to warp, leading to vibrations during braking.
Brake pad wear
Regular use causes brake pads to wear down and they need to be replaced periodically.
Valve cover gasket leak
The 4ZE1 engine is known to develop leaks around the valve cover gasket over time.
Timing belt failure
The 4ZE1 engine uses a timing belt that requires periodic replacement to prevent engine damage.
Head gasket issues
Older models can experience head gasket failures, leading to coolant leaks and engine overheating.
Exhaust manifold cracks
The in-line configuration can place stress on the exhaust manifold, causing it to crack over time.
Fuel injector problems
The fuel injectors may become clogged or fail, leading to poor engine performance.
Ignition system issues
Worn spark plugs, ignition coils, or distributor components can lead to misfires and rough running conditions.
Rust and corrosion
Older ISUZU Pickup models, particularly from the early '90s, are prone to rust and corrosion, especially in the chassis and body panels.
Cooling system failures
Radiators, hoses, and water pumps may develop leaks or fail, leading to engine overheating.
