Pcv System:
The PCV (Positive Crankcase Ventilation) system, integrated into the valve cover, is prone to cracking, leading to vacuum leaks and rough idle.
Cooling System:
Water pump and thermostat failures are common, often with plastic components degrading over time. Requires replacement with the entire assembly.
