Slight Humming Goes Away When Clutch Pressed?

[Wacky Dee]

Hey Guys

ever since I bought my car I've noticed that there's a very slight humming (like aircon fan turned on the lowest setting) coming from the center of the car (transmission?) But if you press the clutch pedal in all the way the noise disappears. If you depress the clutch it comes back ..if you press the clutch it goes away again etc

What could this be a sign of? Cheers

throwout/spigot bearing?

is that a question lol? Because I wouldn't have a clue which is why I'm asking .. are those 2 parts of the tranny and if so, is this a sign of a serious issue looming around the corner or common on 10+ year old cars? cheers

Input shaft bearings.

The throw out bearing will only make noise when you push the clutch in if it's shot.

It's nothing to be overly concerned about.

Pretty much every Skyline I have been in has that. I got my current R34 at about 60,000km's and it had it then, so I don't think it's anything to worry about.
