So 2 weeks ago I changed the oil and the power steering fluid too because it was making whining noises. I change the o-ring a year ago and that fixed it for a short period of time but the whining noise came back.
Now the engine is making this clicking noise that is probably unrelated to the oil and power steering fluid change but I just thought I would throw it in there for reference.

I checked the oil level and it is in between the lines. I used the same engine oil I have been using for the last 3.5 years of owning this car(pennzoil platinum).
I used the turkey baster method for the power steering fluid change. I put newspaper all around and was very careful not to spill anything.

Thanks.

 

sounds like a bad pulley or one of your belts (timing or serpentine)

 

Not too bad of a noise but definitely sounds like one of the pulleys, most likely tensioner

 

What's more likely to fail? There's the alternator pully, air compressor, power steering and serpentine tensioner. Is it common for the serpentine tensioner to fail after a certain period of time?

 

I've seen all fail at some point in time. Rather than worry about the statistical analysis of previous failures as a method of troubleshooting, you should focus on your current situation to determine the failure appropriate to your car.
