Hi guys im having an issue when im up in the rev range i have a horrible noise, almost like a gear is slipping or the clutch is running out, I dont know. Luckily i dont do much work past 3000 rpm but how long before it becomes 2800, 2600, so on?

Any opinions welcomed

Can you describe the noise in more detail? How loud is it? Where's it coming from? Etc... Very difficult for people to contribute without more info.

What I can hear from the cab is like a high speed scraping metal sound from the general area of the engine/ transmisson. Its louder than general engine noise but not by much.
Also i can get an everr so slight feel in th gas pedal, like a vibrational clackity click type feel.
Happens with clutch out and when out of gear too.

What about with the clutch pushed in? Does it disappear?

Well it鈥檚 probably not the clutch or gearbox then. Has the clutch been worked on recently? Thinking perhaps a flywheel bolt worked loose? Or something inside the bell housing rubbing on the flywheel? Otherwise, engine. Bad bottom end bearing?
