Problems:

Oil leaks
Older engines, like the one in the 1984 Jeep CJ-7, can commonly develop oil leaks due to worn gaskets and seals.
Carburetor issues
This model year commonly features a carburetor instead of fuel injection, which can become clogged or out of adjustment, causing poor performance.
Exhaust manifold cracks
The exhaust manifolds can develop cracks over time due to repeated heating and cooling cycles, leading to exhaust leaks and noise.
Cooling system failures
Components such as the radiator, water pump, and hoses can wear out, leading to overheating issues.
Ignition system failures
Points, condenser, distributor cap, rotor, and spark plugs can wear out or fail, leading to misfires and starting issues.
Vacuum leaks
Aging hoses and gaskets can develop vacuum leaks, causing poor engine performance and rough idling.
Fuel pump failure
Mechanical fuel pumps can wear out and fail, leading to fuel delivery issues and stalling.
Timing chain/belt wear
Over time, the timing chain or belt can stretch or wear out, causing timing issues that affect engine performance.
