Problems:

Oil leaks

Common in older engines, and the 5M-GE is no exception. Gaskets and seals can wear out, leading to oil leaks.

Overheating

This can be caused by a failing radiator, water pump, or thermostat. In older models, clogged or corroded coolant passages can also be an issue.

Timing belt failure

The 5M-GE engine uses a timing belt that needs regular replacement. If not maintained, it can break and cause significant engine damage.

Fuel injector issues

With electronic fuel injection, clogged or failing fuel injectors can lead to poor performance and reduced fuel efficiency.

Vacuum leaks

Old hoses and gaskets can develop leaks, leading to rough idling and poor engine performance.

Head gasket failure

Older engines like the 5M-GE may suffer from head gasket issues, leading to coolant and oil mixing, overheating, and poor performance.

Ignition system problems

Worn out spark plugs, ignition wires, and distributor components can cause misfires and poor engine performance.

Sensor failures

The electronic fuel injection system relies on various sensors (e.g., oxygen sensor, throttle position sensor). Failure of these sensors can lead to poor engine performance and increased emissions.

TOYOTA Supra 1985

The 1985 Toyota Supra GT is a sporty hatchback powered by a 2.8L inline-six engine with electronic fuel injection, producing between 145 to 175 hp. This rear-wheel-drive classic features a dual overhead cam (DOHC) design and manual seat belts. Manufactured in Toyota City, Japan, this model exemplifies Toyota's engineering excellence from the '80s.

Problems:

Overheating

The Toyota 5M-GE engine can be prone to overheating issues, often due to a failing radiator, water pump, or thermostat.

Head gasket failure

Due to the age of the vehicle, the head gasket may fail, leading to coolant and oil mixing, which can cause severe engine damage.

Vacuum leaks

The complex vacuum lines in the 5M-GE engine can develop leaks over time, causing rough idling and poor performance.

Ignition system problems

Faulty spark plugs, ignition wires, or distributor issues can lead to misfires and reduced engine performance.

Fuel injection issues

As the engine uses an electronic fuel injection system, problems with fuel injectors, sensors, or the ECU can lead to poor fuel economy and engine performance.

Timing chain wear

Over time, the timing chain can stretch or wear out, leading to poor engine timing and performance issues.

Oil leaks

Commonly, valve cover gaskets and oil pan gaskets may wear out and cause oil leaks.

Egr valve malfunction

The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, leading to increased emissions and engine performance issues.

TOYOTA Supra 1984

The 1984 Toyota Supra GT is a classic hatchback powered by a 2.8L in-line 6-cylinder engine, delivering 145-175 hp. This rear-wheel-drive car features electronic fuel injection and a dual overhead cam design. Manufactured by Toyota Motor Corporation in Toyota City, Japan, it embodies the sporty spirit of the 80s with its sleek design and performance capabilities.
