Sorry, I'm new to the site and cannot figure out how to search for a specific issue already delt with #1.
#2, I have this clicking in the very front passenger side of the engine, not in the engine. Clicking I cannot find; car runs fine but did just have to replace 1 MAFS. I put a long steel rod to components up front but cannot find it. Lubed belt but does not sound like that.

Mileage? High mileage could be a stretched timing chain

It has 60K miles, do I just need to replace chain or other parts with the chain? I do all my own work (most of the time) is this hard to do?

60k isn't enough for timing chain

I thought 60k was a bit low for the chain. Any other ideas from anyone. Standing in front of the car, to the left (passenger side) it has this click,click,click sound. Loud enough you do not have to open hood but not so loud you can hear it passing by somone (if that made snese). It must be warmed up before you can hear it. Thanks for the help.
