I have a 2000 Maxima SE, 5-speed. Over the past month I have been noticing a clicking noise coming from the engine bay on the the passenger side. It is inconsistent in when it occurs and in volume and, but its only really noticeable when idling (whether thats because I can't hear it while driving, I don't know). It doesn't only happen on cold starts, and sometimes doesn't happen until it gets warmed up. Sometimes it loud enough to hear in the cabin, sometimes not, and some days I don't notice it.

Here is a video w/sound. This is not at its worst, but it is noticeable. I actually had to start and idle the car for a few minutes before it would start.

In my search of past posts I have seen everything from low oil, to knock, to timing chain. Does this description and video give anyone any idea as to what it may be?

Thanks!

 

Sounds like your timing chain.

 

lots of people have a similar sound on startup due to low initial oil pressure. Check your oil level or you may need to change to a different oil viscosity
