Do you hear the chatter behind it all?

Kind of hear what sounds like lifters. When was the last time they were adjusted?

 

[tacojoel]

I think it's the other noise like pulley or tensioner bearing going south.

Never. as far as I am aware

 

[Rock62]

Must be a journal bearing on one of the connecting rods in the process of dying.

 

[JayQQ97]

That doesn't sound good at all

 

[Rock62]

Maybe a main bearing on the crankshaft.

 

[Rock62]

Ok....seriously.

Sounds like a bearing going out in the serpentine belt system.

Quick way to check. Remove the serp belt, then run the engine for a few minutes. If the noise goes away, then you have narrowed the search. If the noise persists, then reinstall the belt and look to other possible sources.

Don't bother asking if the belt can be removed with one arm. If you can't find an able body who can.

 

[JayQQ97]

that doesn't sound good either!

Are these engines warrantied at all to 100k miles?

Most likely have exceeded the time limit.

At this point probably find a good mechanic to diagnose the problem. You have too many different opinions on a poor quality video. Everyone is just guessing.

would that lifter fix/adjustment involve removing the valve cover?
is diy possible for it?

Unless you know what you are doing, take it to dealer. You could screw it up. Not like old school motors.

 

[Rock62]

Careful. The subject is posted in the 70,000 mile topic.............

Agree with TacoKen. Take it to a dealer.

 

[JayQQ97]

will it throw a CEL code if it gets out of normal?

 

[Rock62]

I'm sure if it gets bad enough the ECM throw some code.

But, the code may indicate a separate problem that is a symptom of the valve clearance.

Go to a Toyota mechanic. Or just run it as is. I'm sure the engine will eventually fail confirming a problem.

You could always dump in a higher viscosity oil to mask the sound. This is an old trick for selling clapped out rides.
