The 3RZ-FE engine was developed in 1994 and turned out to be not only the most powerful, but also the most successful example of the “RZ” series of motors. In this engine, Toyota designers managed to optimally use the main advantages of the I4 inline 4-cylinder layout (low manufacturing cost, simplicity and reliability of operation) and at the same time minimize its disadvantages due to the use of a complex balance shafts in the design.
As a result, Toyota received a fairly powerful and inexpensive gasoline engine, which was successfully installed on jeeps and numerous minivans of the company for 12 years both domestically and in other automotive markets of the world (Europe, North America, Asia and the Middle East).

Frequent problems
The 3RZ series of motors are designed in such a way that during their correct operation, serious problems almost never arise. The secret lies above all in the at the same time simple and at the same time reliable design of the engine and its components.
The main thing is to regularly carry out maintenance, adjust the valves in a timely manner, fill in oil from only a trusted manufacturer and refuel with high-quality gasoline. With this approach, you can forget about major repairs forever.
The durability of the unit often exceeds 400 thousand km. However, we must not forget to check the timing chain for relaxation every 200 thousand kilometers. Typically, the problem is accompanied by a characteristic sound.
