You'll have to rig up some noise pipes/sticks
and track the noise down. IE: a piece of PVC
pipe makes a decent stethoscope for trying to
narrow it down.
The first thing I would be suspecting would
be bearings in whatever.. Belt tensioner, belt,
alternator bearings, etc.. But there is only
one way to find it and that's to listen real
carefully.
engine noise
Linear Mode
