You have a timing chain in your 2zr engine. I’m not certain if there’s a recommended mileage to replace the timing chain. Though, if you have no service history, you can remove the valve cover and put cylinder 1 at top dead center and verify the chain. If there’s slack at cylinder 1, then it’s time for service. This includes the timing chain guides, vvt sprocket on the intake cam and oil pump.

 

Thank you

 

It should tell you in the owner’s manual.

 

I looked in the manual and it didn’t mention anything about it. It mentions to inspect driving belts. I’m at 120,000 miles

 

In the old days, many American made cars' timing gears were plastic coated. After the chain wore a certain degree, the coating would flake off, throwing the timing off and the engine either barely ran or wouldn't run, but that saved it from crashing the valves. Replacement of the chain and gears was the remedy- if you knew what to fix. Otherwise a lot of them went to the junk yard with about 100,000 miles on them. Your Toyota is not like that.There you are going 150,000- 200,000 miles and the timing chain is still good.

 

There might be a separate manual just for scheduled maintenance.
My ‘07 Camry has one.

 

If you just do regular oil changes (every 6-months or 5,000 miles), you'll never have to worry about it until many years from now. Our old Corolla (2008) is going on 200,000 miles and running like a champ.

 

Guy at work has a 2011 with just shy of 300K miles and has never even removed the timing cover. Quiet as can be.
