Timing chains are designed to normally last the life of the engine and are replaced when the engine is rebuilt.
The timing chain on a 2000 BMW Z3 typically does not require regular replacement like a timing belt, as it is designed to last the lifetime of the engine. However, it’s essential to inspect it for wear or damage during regular maintenance, especially if you notice any unusual noises from the engine or if the vehicle has high mileage (over 100,000 miles). If you experience issues such as engine misfires or performance problems, a timing chain replacement may be necessary. Always consult the owner's manual or a professional mechanic for specific recommendations based on your vehicle's condition.
The BMW z4 replaced the BMW z3 in late 2002. The BMW z3 was introduced in 1996 shortly after staring in a James Bond movie. Not as easy on the eyes as the z3 but just as nice.
the general rule of thumb is at or around 100k miles. this varries with manufacturer, but it is best to always replace no later than 125k
