Engine click sound

[imactj2004]

please look (listen) to the two videos. what is the cause of the clicking sound in second video (4835.mov)? should I be concerned?

Havent been able to determine any pattern to this behavior, but seems to be there 50% of the time.

I don't hear a clicking sound in your video.
Unless you're taking about the constant ticking?
However, I do have my own weird clicking sounds on mine that I have deemed normal.
