1. Is it normal for the car to shake a bit while you slowly disengage the clutch on first gear? Or is it because the clutch maybe worn out.

2. Whenever i turn the car off, i hear a clicking noise. Is it because of the belt is made out of chain instead of rubber?

3. Everytime I engage or disengage the clutch i hear a clicking noise aswell.

4. Everytime I am in 4th gear and i let go of the gas, I hear a whining noise. It only happens on 4th gear.

 

Clicking noises while the car is cooling down is a normal thing. As things cool there are expansion joints in the exhaust that shrink back down to normal size.

Can't speak of the other issues.

 

Bump!
