L3 engine modifications:
L3-VE (naturally aspirated):
- It was installed on mass-produced Mazda models, including the Mazda 6 and the second-generation Mazda 3.
- Easy to maintain and reliable engine.
- Main problems: oil leakage through the valve cover gasket and timing chain wear at mileage over 150 thousand km.
L3-VDT (turbocharged):
- It was used on sports versions, such as the Mazda 3 MPS, Mazda 6 MPS and CX-7.
- It was distinguished by its power and quick response to gas.
- Weak points:
- Turbine overheating under high loads.
- Increased oil consumption.
- Sensitivity to fuel quality.
Problems and maintenance of the L3 engine:
Oil consumption:
Especially on turbocharged versions. Check the oil level every 1-2 thousand km.
Timing chain wear:
The chain stretches at about 150-200 thousand km. Replacement is required along with the tensioner.
Turbine (L3-VDT):
Sensitive to overheating. Regular oil changes and the use of high-quality fuel extend its service life.
Sensors:
There may be problems with the mass air flow sensor (MAF) and lambda probe.
Advantages:
- Reliability and durability with timely maintenance.
- Good power and economy for its volume.
- Compatibility with various car models.
Engine life:
With proper care, naturally aspirated versions can travel up to 300–400 thousand km, and turbocharged versions – about 200–250 thousand km before major repairs.
