Problems:
Oil leaks
The 3MZ engine, especially in older models like the 2004 Lexus ES, can develop oil leaks from the valve cover gaskets and oil pan gaskets due to age and wear.
Timing belt wear
The engine uses a timing belt that requires periodic replacement. If not maintained, it can cause severe engine damage.
Coolant leaks
The V6 3MZ engine has been known to develop coolant leaks from the water pump or radiator, which can lead to overheating issues if not addressed.
Ignition coil failure
Ignition coils can fail over time, leading to misfires, rough idling, and poor engine performance.
Carbon buildup
V-shaped engines, including the 3MZ, can suffer from carbon buildup on the intake valves, leading to reduced performance and fuel efficiency.
Oxygen sensor failure
Older models like the 2004 Lexus ES may experience oxygen sensor failures, which can result in poor fuel economy and increased emissions.
