re: 2012 Honda Accord timing chain

Unless it's making noise or your check engine light is on with a related code I say leave it alone. With proper maintenance, such as regular oil changes, a timing chain will last to 150,000 miles and beyond. I say save your money! Hope that helps! Jim

Frequent oil changes will help your timing chain last longer. Chains have hundreds of small parts that wear. Any wear makes the chain stretch which will eventually cause a chain rattle. Changing oil at long intervals only saves money in the short term.
