The chain itself last a very long time. However, if your chain isn't going to wear out, then other parts will wear out. From my past experience with BMW engines running on timing chains, what needs to replaced over time will be the chain tensioner. sometimes the guide rails, After around 100-150K miles, the gears on the cams will start to wear out as well. The teeths will no longer be sharp an start to become round. Then you will need to replace the gears (might as well replace everything together including chain).

 

I have yet to hear any issues of chain snapping but there are disasters of chains skipping over the gears due to worn gear teeth and damaging the engine (valves open and close at wrong timing and it hit the pistons and got bent).

 

IMHO, its not possible for timing components (chains, gears etc...) to last a lifetime. Definitely have to replace some point of time one.

What are the disadvantages of timing chains compared to belts?

 

What are some cars still running on belts when chains seem to be more reliable?

Discussed to death already. Both have pros and cons.

 

Timing chain may also give you problem though need not change as often as belt. Some timing chain problem - cam chain tensioner kaput, chain guide problem, if chain snap will be worse than belt snap, chain is noisier.

 

Overall, chain is sturdier, requires less frequent maintenance. Most loved by Singaporean drivers.

Now most new models no matter the makes uses timing chain as standard. Unlike cars of olden days.

 

Maintenance is not an issue since most cars seldom lived beyond 10 yrs old. Such a shame that cars in new like condition is being forced to scrapped,

timing belt getting old tends to break, once break engine cannot start and may damage engine.

 

timing chain will not break, so far nvr heard of this case, it will give you abnormal "craggg craggg " sound to hint for replacement, it is safer

Hi All,

 

Sorry as my account is restricted have to use an old thread.

 

Recently when I went for servicing for my 05 Altis (COE renewed), the mechanic recommended me to change the timing chain tensioner. The price quoted to me was $200. I would like to know whether this is a fair price as I am not familiar with car repair prices except for normal servicing.

 

Thank you.
