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) Link to video 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.

Hi, My 350z has just recently started making a quiet whining sound at 50mph and above. I don't believe its engine related as the whine doesn't change with rpm just speed and I don't think its gearbox related as it still makes the sound in neutral/with the clutch press in and in all gears. Does this sound like a wheel bearing or differential issue? The sound gets louder the faster I go and disappears below 50mph. Any help would be appreciated. Thanks
