A trusted Mercedes mechanic says to change chains every 300k miles.

Since I'm at 120k miles, I've been wondering about this timing chain issue. Has there been any change on the thought of when it needs to be replaced?

The other issue I have is that I'm on my second short block which was replaced at 76k miles. What are the odds that Honda used a NEW timing chain when using the same head?

I've yet to read on s2ki anybody having issue with a broken chain. Looks like you'll be the one telling the rest of us when/if it needs to be changed, joe.

If you need to change the timing chain at around 100,000 miles, then why didn't Honda just stick with a belt on this engine? A belt is supposed to be changed around 90,000 to 100,000 miles anyway.

chains are basically good for the life of the engine. the only reason you'd replace them is when you rebuild the engine. the only thing that can go wrong with them is the links could stretch/deform.

This is just a thought but, if the HONDA SERVICE MANUAL doesn't list it as required maintenance then it doesn't need to be replaced...ever.

That's what I was thinking.

I would tend to agree with this. As an addendum, if you feel the chain is worn enough to warrant replacement, you should also consider replacing the drive gears too. If the chain is worn that badly, it's a good bet that the gears have significant wear too. Putting a new chain on a worn set of drive gears will significantly reduce the life of the new chain.

Just a thought!

Thanks for all the input! This is my first timing chain equipped vehicle and I just wanted to prevent the dreaded "timing-belt" disaster.

So who do I send the bill to when it breaks off and destroys my engine?
