When would you replace Timing Chain?

[Bugdude]

Having to replace the motor in my '93 Toyota pickup. Got a motor out of a wrecked '94 with 60,000 miles on it. Was wondering at what mileage would you all suggest replacing the timing chain. Had considered replacing it before the motor went in, but not enough time to do so. So I will be doing it at another time.

So what mileage would you all suggest?

Thanks.

I would change it out when the engine hits 100,000 miles.

Timing chains should be replaced every 75,000 miles. Timing belts should be replaced every 100,000 miles.

Other way around. belt at 75K chain at 100K. Most people dont bother changing the chain at all unless there a problem with it.

I didn't replace my chain on my 1992 toyota pickup untill i had 120,000 miles on it. It started making a clicking noise so i changed it out and everything is fine again.

Here's the latest word on timing belt maintenance from Toyota.

How do you come up with these off-the-cuff comments and then in your second post provide a link that proves it?

Well, the 75,000/100,000 comment was from memory. I have a service manual for '85-'93 Toyota trucks and SUVs. I used to read that book all the time, and thats how I remember that number.
However, when people tell me Im wrong, I tend to go in search of undeniable proof.
Thats how I came up with the link. Solid evidence like that tends to shut people up very quickly!

I guess there are a whole host of factors that go into that answer. I have 165,000 miles on my 21 year old original chain whitout any problems. I personally know two people with 250,000 and 209,000 on their original chains without any problems, but I just talked them both into changing them recently. I have heard of them breaking as early as 75,000 miles and lasting beyond 360,000 miles. I think it all depends on proper maintance (ie oil changes, good quality proper anti-drainback valve oil filters....mabey even synthetic oil) and driving styles.

I replaced mine at 89K miles (22re). The chain didn't break, but the little plastic guide did, which allowed me to hear the chain flapping against the cover. Personally, if nothing is wrong with it, i'm not going to change it at a pre-determined interval...primarily because you have to rip nearly the whole damn engine apart. I did manage to do it without taking the head off though. That saved me quite a bit of time.

timing belts need to be replaced every 60k-75k depending on the engine. interference types should be replaced at MAX 60k.
timing chains don't need to be replaced unless they're causing a problem... i know of a toyota that's daily driven and has the original chain after 290,000mi,

[Bakemono]

Right, thats why Toyota says to replace the timing chain "as needed".
