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.
