Problems:

Oil leaks
The KA24DE engine is known for developing oil leaks over time, especially from valve cover gaskets and front and rear main seals.
Timing chain noise
The timing chain on the KA24DE can become noisy due to worn tensioners and guides, leading to a rattling sound.
Overheating
The 240SX can experience overheating issues if the cooling system is not properly maintained, including problems with the radiator, water pump, or thermostat.
Idle issues
The idle air control valve (IACV) and mass air flow sensor (MAF) can cause irregular idling or stalling problems.
Head gasket failure
With age and high mileage, the KA24DE engine may develop head gasket issues, leading to coolant leaks and potential engine overheating.
Power loss
Older engines may experience power loss due to wear and tear on internal components or issues with the fuel injection system.
Exhaust manifold cracks
The stock exhaust manifold can develop cracks over time, leading to exhaust leaks and reduced engine performance.
Egr valve problems
The exhaust gas recirculation (EGR) valve can become clogged or fail, causing rough idling and increased emissions.
Sensor failures
Sensors such as the oxygen sensor, crankshaft position sensor, and camshaft position sensor can fail, leading to various engine performance issues.
Fuel injector leaks
Over time, fuel injectors can develop leaks or become clogged, leading to poor fuel efficiency and engine misfires.
