Problems:

Oil leaks
The KA24DE engine can develop oil leaks from the valve cover gasket, oil pan gasket, and front and rear main seals.
Timing chain rattle
Over time, the timing chain and its tensioners can wear out, leading to a rattling noise, especially during startup.
Head gasket failure
The head gasket can fail, causing coolant leaks and potentially leading to overheating and engine damage.
Fuel injector issues
Fuel injectors can become clogged or fail, leading to poor engine performance and misfires.
Coolant leaks
Coolant leaks can occur from the radiator, hoses, or the water pump, leading to engine overheating if not addressed.
Idle air control valve problems
The idle air control valve can become dirty or fail, causing rough idling or stalling.
Mass air flow sensor failure
The mass air flow sensor can fail or become dirty, affecting the air-fuel mixture and leading to performance issues.
Crankshaft position sensor failure
The crankshaft position sensor can fail, causing the engine to stall or not start.
