My wife's 2011 Sequoia had a strange engine noise only when the vehicle is cold, and it only lasts for a few minutes after startup. The noise has been getting worse over time.

I've changed the idler and tensioner because they were original and needed to be replaced (they were making a bit of noise as well) and I didn't change this noise (figured it wouldn't).

I'm thinking it might be a lifter, but I just don't know enough about this motor.

Thanks in advance for any help.

Well, after digging around a bit more, I found this video.


Looks like it could be either a VVT solenoid or maybe more likely the chain tensioner?

Have anyone had this issue?
