Noise in the transmission or engine when can is on neutral

SOURCE: Front End Noise in 2005 Nissan, Maxima

it would not hurt to check rear tire wear due to misalignment
cupped tires will cause a faulty bearing type noise or humming.

It's the throw out bearing. They probably call it a Clutch Release Bearing.

Envision a round large thick tube. On this tube put a bearing at the end of it. Now put a thick metal doughnut on that bearing. The thick metal tube stays stationary, and the metal doughnut spins.
The bearing this 'metal doughnut is riding on, is bad.

Solution? Have this throw-out bearing replaced.

1st check the the oil level and the vehicle's oil type.(owners manuel) 5w30-10w30
10w 30 is a thicker oil and could possibly be causing this.(Moves more freely through the engine heats the oil)

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.
