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

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.

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

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

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

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

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

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.

The Toyota 22R engine is known for developing oil leaks, particularly around the valve cover gasket and the timing chain cover.

Over time, the timing chain on the 22R engine can stretch and wear out, leading to poor engine performance and potential engine damage if not replaced.

The 1984 Toyota Celica with a 22R engine may experience problems with the carburetor, such as clogging or improper fuel mixture, leading to rough idling and poor acceleration.

This engine can suffer from head gasket issues, which may cause coolant leaks, overheating, and white smoke from the exhaust.

Vacuum hoses and lines can become brittle and crack over time, causing vacuum leaks that lead to rough engine performance and increased emissions.

Issues with the distributor, spark plugs, or ignition wires can result in misfires, poor fuel economy, and difficulty starting the engine.

The cooling system, including the radiator, water pump, and hoses, can experience leaks or failures, leading to engine overheating.

The exhaust manifold on the 22R engine is prone to cracking, which can cause exhaust leaks and increased engine noise.

The mechanical fuel pump can fail over time, leading to fuel delivery problems and engine stalling.
