RW> RS> Was wondering I recently have one heck of a noise and shake comming
RW> RS> from my
RW> saturn 1.9liter engine From what i can see at looking at
RW> RS> the Belt tensioner  it seems to be Jumping

RW> RS> it possible that the bearings in the tensioner may
RW> be shot and this
RW> RS> is what is causing the shake

RW>Yeup...

RW> RS> , and the really bad rattle
RW> noise , its like the exhaust heat
RW> RS> shield is rattling , but if you drive it

RW> RS> goes away ,

RW>The bearing is worn and loose, but is re-tensioned by the change in engine

RW> RS> its mainly when your at idle or put it in

RW> RS> reverse especially it vibrates like crazy I didnt notice any of the
RW> RS> mounts on the engine to be bad

RW>Buy a new tensioner and replace it or have your mechanic do it for you.
RW>That should fix the noise and shaking.

That was my thought also. As I recal the maximum load in on the
tensionor with the engien stolled ans runing at Idel. As the engine
speeds up the loading on the Tensionor lightens up slightly
