350z engine noise ticking

[chris_h]

I bought this car about 3 months ago and it has always had a tick, the engine works perfectly and has no other issues. The car also has full service history from dealers,  The oil pressure is where it should be and had a service around 3000 miles ago.

 

I searched the topic and looked through a few forums and people usually mentioned the fuel dampers. injectors being loose or loose cam chain tensioners. But they say that if you rev the engine it should tick quicker however mine doesn’t seem to do that.

 

I’ve attached a link to a video of what the engine sounds like (YouTube has compressed it so it sounds a bit deeper than it actually is)

This is while the engine has been on about 5 minutes.

 

Any opinions on what I should do next to diagnose or any input would be appreciated.

 

The sound is loudest above the heads at the top of the engine.
