Title: Tapping sound
Post by: Lorsar on December 30, 2021, 02:34:25

This tapping sound started recently.

It appears to be in the front by the fan.  Any suggestions on what it might be or where to start troubleshooting?

it seems to be synchron with one belt turn ?
Mark one belt each time and try to count?

Yes, it is in sync with the engine rev and goes faster when you increase the rev

So you can identify what belt is involved and have a look all around it and find what tilt it

Sounds a lot like an exhaust leak to me.

Had some warmer weather for a  few days so I was able to get it up on ramps and look from underneath.  It looks like the alternater belt is slapping and upon closer inspection, there is a few chunks missing in it.  New belts are on order.
