How often or common are these things going bad? I have noise from my motor and someone suggested the timing belt tensioner.1 day it will sound like a slight bearing tapping or rapping and the next like a heat sheild sound from the side where the timing belt is.Any Idea's

 

Just from a touch or visually does the timing belt seem loose?

 

I'm just going by the noise of it.It sounds like a faint bearing noise but it has changed from day to day.1 day like a bearing constant and the next like a metal tin rapping or vibrating on and off.It has just started this noise the last 2 weeks.The car doesnt burn any oil and has all kinds of power.

 

Aaaa..... You should not drive a car that is making wierd noises (unless you know what they are)

Take it to a mechanic if you can't figure it out.

How many miles?
Last T-belt change?
Tensioner done with it?
