Are you kidding? Timing chains are generally lifetime. I've never had a vehicle with a chain needing to be replaced. I had a 91 Benz 300E that I sold with 365k miles, never touched the chain. Chains don't need maintenance and 150k is not even beginning to scratch the surface of timing chain life.
NO I am not kidding, understandable but this is what I do for a living been doing it for 45 years, I see the best and the worst. I have seen numerous times where timing chains have had to be replaced due to failure before 100k, whether that be due to a broken guide, tensioner failure or stretched/broken chain. Nothing is lifetime on a car, it may be intended to be but may not last.
