When should I change my BMW 740 timing chain?
I asked a service rep at Classic BMW in Plano that question and he said "never". The 740 has a timing chain, not a timing belt. Cars with timing belts usually have to change it every 80-100k miles, but this does not apply to timing chains. If your timing chain is intact, you should not have to have it replaced. Chains do not stretch or wear out. More likely, if you have a E38 (1994-2001), the timing chain may rattle, which is NOT an indication of a problem with the timing chain. There is a timing chain tensioner that loses its ability over time to apply proper tension to the chain, and that is a relatively easy and inexpensive replacement. Another well-known problem is that you may eventually need to replace the timing chain GUIDES, which is plastic and can wear and break off over time.

The 1990 Volvo 740 GLE is equipped with a B230F engine, which is considered a non-interference engine.

Regular maintenance of the timing belt is still crucial to ensure the engine operates smoothly and reliably.

Not mine , I was doing about 70 when my belt broke . It took me 4 hours and $20 to know for sure boy how aggravating not knowing if my valves were bent or not.
