At what mileage did you change your v6 timing chain? - Toyota 4Runner Forum

I'm just curious. What's your mileage when you changed your timing chain? I'm at 150000 miles now and change my oil every 10000 miles or 1 year. So far, I've never had a problem. If you can share your experiences, I would really appreciate it. Thank you.

There's no need to change your chain.

You change your oil every 10,000 miles?

I was thinking the same, better off at 5k intervals

Changed my at 125k - was having a check engine light

Yup no need to replace your timing chain, only timing belts need to be changed.

In addition, start changing your oil every 5k-6k (if using synthetic oil) and that will prolong the life of your timing chain.

I replace my oil twice a year (5-6k). Once before winter and once before summer time.

Im still on the original timing chain at 254k miles.

Hopefully I never have to do this.

Your best defense is staying on top of your oil changes. Read: Timing Chain Stretch: It Is The Oil's Fault!

10k is probably fine with a synthetic, but oil is cheap and oil changes on our v6s are easy. I change every 5k with a full synthetic.

I changed mine at 150k.

For reference I change my oil every 5k with a synth-blend. Engine is just over 250k with nary a tick.

Timing chain is original and should outlive me. My biggest problem is I've never changed the trans fluid, but it is on my list to do a fluid exchange in the next couple weeks before spring.

I replaced my chain after it stretched at 120k. The dreaded P0016.

I'm at 513,535 miles, and I still have the original chain. Also, not that this suddenly on oil change thread but I use Mobil 1 Extended Performance and change every 15k+.

I’ve had oil analysis done on various synthetics and the TBN is still quite high after 6-7K miles. The oil is still comfortably within spec and hasn’t sheared down.
10K is no problem on the V6 with any reputable brand of synthetic oil.

I think checking the level frequently and topping up is probably just as important as regular oil changes. If the chain is starving for oil it’s going to heat up and wear out faster.

I’m also on the original chain.

That's always wonderful to hear! I hope I get many miles out of my 08 T4R. I also used MOBIL 1. I use it on my motorcycle chain instead of chain lube. Thin coat applied as needed. No wear on sprocket or chain in over 13k miles. I am hard on the throttle too! The claims Mobile 1 state are fact

What model year? Any other issues? Head gasket?
