Problems:
Oil leaks
Older engines, especially from the late 80s like the 1989 Jeep Comanche, are prone to oil leaks due to worn gaskets and seals.
Overheating
The cooling system in older vehicles may become less effective over time due to radiator clogging, thermostat failure, or water pump issues.
Vacuum leaks
In-line engines with multiple cylinders, such as this 6-cylinder engine, often develop vacuum leaks which can lead to poor engine performance and fuel economy.
Worn timing chain/belt
As vehicles age, the timing chain or belt can wear out, leading to poor engine timing, misfires, or even engine failure.
Fuel injector problems
Older fuel injectors can become clogged or fail, leading to poor fuel delivery and engine performance issues.
Ignition system issues
Components like the distributor, spark plugs, and ignition coils can degrade or fail over time, causing misfires and starting problems.
