For owners of the Ford Ranger with the 4.0 engine, one issue that hasn't been mentioned yet is the tendency for the engine to develop oil leaks, especially around the valve cover gaskets. This can lead to oil dripping onto hot engine parts, causing smoke and a burning smell.

Another potential issue is the failure of the thermostat housing, which can cause coolant leaks and lead to overheating. Keeping an eye on your engine's temperature gauge and inspecting the thermostat housing during routine maintenance can help catch this issue early.

Lastly, some owners have reported problems with the mass airflow sensor (MAF) becoming dirty or failing. This can lead to poor engine performance and reduced fuel efficiency. Cleaning or replacing the MAF sensor can often resolve these issues.
