Cripes, given your name I’m guessing you know stuffs about cars and things. You’re making me paranoid.
I don’t know if my ‘09 Corolla has a single or double row. I did a ton of research on Toyota Nation and the consensus there is that ‘09 corolla with my engine has a 400k + life unless you hear “the noise.” Which is loud and distinctive.
I have been working on cars (boats and anything mechanical)for
over 45 years (yes, I am old).
Your Corolla, with proper maintenance, should go 200k without
any problem. If, however you hear a noise (usually at start up), it should be checked out.
Replacing a timing chain proactively can create more problems
since the engine needs to be opened up.
No doubt, your Corolla will go as long as you want to drive it.
