The BMW Z3 typically has a timing chain rather than a timing belt, which generally does not require regular replacement like a belt would. Timing chains are designed to last the lifetime of the engine, though they can wear out or become stretched over time, especially if the engine has high mileage or has not been properly maintained. It's important to monitor for signs of wear or noise, and if issues arise, a replacement may be necessary. Regular oil changes and maintenance can help prolong the life of the timing chain.
