Since the first models, Toyota Corolla engines are known for their reliability, performance and long service life. To date, 12 generations of power units have been produced. Toyota’s ZZ inline engines are equipped with a pair of chain-driven camshafts. The cylinder head is 16-valve. The volume of the power unit of the 4ZZ-FE model is 1.4 liters, while the power reaches 97 hp. at 6000 rpm. The 4ZZ FE engine was based on the earlier 3ZZ. The previous generation powertrain was fitted with a smaller crankshaft. In fact, the 4ZZ is no different from the three previous versions.

- Oil burnout. A characteristic feature of motors manufactured before 2002. The main reason lies in the oil scraper rings. It is better to replace them with analogs released after 2005, and there will be no problem. Decarbonization is not applicable in this case.
- A dull sound in the motor. Most likely, the timing chain was stretched, which is not uncommon after 150 thousand kilometers. We need to replace it. The chain tensioner drive itself may also fail. Valves do not knock.
- Floating turnovers. The problem can be eliminated by flushing the throttle delay module as well as the idle valve.
- Body vibration. The rear engine mount can cause this. Although the motor might just vibrate by itself.
The disadvantage of units of this series is their extreme fear of overheating. Because of this, the cylinder block can move. As a result, it will need to be replaced. Boring in this case is not welcomed and is not approved by the official manufacturer. In general, the engine resource is also not very long – only 200 thousand km. However, in most cases, copies released not earlier than 2005 are completely serviceable and problem-free in operation.
