Most common problems:

1. overheating

The 1987 Jeep Cherokee with an in-line 6-cylinder engine is prone to overheating due to its cooling system design, which may include issues with the radiator, water pump, or thermostat.

2. oil leaks

This model is known for developing oil leaks, often from the valve cover gasket or rear main seal, which can lead to low oil levels and potential engine damage.

3. rough idle

The engine may experience rough idling caused by issues such as worn spark plugs, a dirty throttle body, or vacuum leaks.

4. fuel injector problems

Fuel injectors can become clogged or fail, leading to poor fuel delivery, misfires, and reduced engine performance.

5. exhaust manifold cracks

The exhaust manifold on this model can develop cracks due to thermal expansion and contraction, leading to exhaust leaks and increased engine noise.

6. timing chain wear

Over time, the timing chain can stretch or wear, causing poor engine timing, which can result in rough running or engine misfires.

7. sensor failures

Various sensors, such as the oxygen sensor or coolant temperature sensor, may fail over time, leading to incorrect engine management and poor performance.

8. coolant leaks

The engine may develop coolant leaks from various points, such as the radiator, hoses, or water pump, which can lead to overheating if not addressed.

9. crankshaft position sensor issues

A faulty crankshaft position sensor can cause starting problems, misfires, or stalling, as it affects the engine's ignition timing.

10. carbon buildup

Over time, carbon deposits can build up in the combustion chamber, affecting engine efficiency, performance, and emissions.
