Loud clicking noise coming from .......
 

I have a 2004 Maxima with 93K miles....recently (last 3 weeks) there has been a clicking noise that sounds like it is coming from inside the engine....but what do I know.
I have checked the oil level and it is fine. The noise is getting louder......any ideas?

Has anyone had any issues like this?

Friends have suggested checking out the serpentine belt or transmission.

Any input would be appreciated.
