Problems:
Head gasket failure
The 7M-GE engine is notorious for head gasket issues, often due to insufficient factory torque specifications on the head bolts. This can lead to overheating and loss of engine compression.
Blown head gasket
Due to the head gasket failure, you may experience coolant mixing with oil, white smoke from the exhaust, and loss of engine power.
Oil leaks
The 7M-GE is prone to oil leaks from the camshaft seals, valve cover gaskets, and oil pan gasket. This can result in oil dripping under the car and low oil levels.
Idle control valve issues
Problems with the idle control valve can cause rough idling or stalling, especially when the engine is cold.
Timing belt wear
The timing belt on the 7M-GE needs regular replacement to avoid the risk of it snapping, which could cause severe engine damage.
Fuel injector problems
The electronic fuel injection system can develop issues over time, like clogged or leaking injectors, affecting engine performance and fuel economy.
Crankshaft pulley failure
The crankshaft pulley, also known as the harmonic balancer, can fail, leading to misalignment of the timing belt and potential engine damage.
Coolant system failures
Weak points in the cooling system, such as the radiator and water pump, can lead to overheating if not properly maintained.
Throttle position sensor (tps) issues
A faulty TPS can cause erratic acceleration, poor fuel economy, and engine stalling.
TOYOTA Supra 1987
The 1987 Toyota Supra Turbo is a classic hatchback featuring a 3.0L inline-6 engine with a turbocharger. Powered by the 7M-GTE engine, it delivers a thrilling performance with electronic fuel injection and dual overhead cam design. Manufactured in Japan, this iconic model remains a favorite among car enthusiasts.

Problems:
Head gasket failure
The 7M-GTE engine is notorious for head gasket issues due to insufficient factory torque specifications on the head bolts.
Rod knock
Over time, the connecting rod bearings can wear out, causing a knocking noise, especially if the engine has been subjected to high power levels or poor maintenance.
Turbocharger problems
The stock turbocharger can wear out, leading to issues such as oil leaks, loss of boost pressure, and decreased performance.
Idle issues
Problems with the electronic fuel injection system or sensors (such as the idle air control valve) can cause rough or unstable idling.
Crankshaft pulley failure
The crankshaft pulley (harmonic balancer) can develop cracks and eventually fail, causing engine vibration and potential damage.
Oil leaks
Common areas for oil leaks include the valve cover gasket, camshaft seals, and front main seal.
Cooling system problems
The cooling system can develop issues such as radiator leaks, water pump failure, or thermostat problems, leading to overheating.
Sensor failures
Various sensors (e.g., oxygen sensors, coolant temperature sensors) can fail over time, causing engine performance issues and check engine lights.
TOYOTA Supra 1987
The 1987 Toyota Supra is a classic hatchback featuring a 3.0L inline-six engine with electronic fuel injection and a dual overhead cam design, crafted by Toyota's renowned 7M-GE engine line. This sporty three-door model offers a compelling mix of performance and practicality, all while maintaining a gross vehicle weight under 6,000 lbs.
