RE: Thumping Sound

No a thumping sound isn't normal.. and could be caused by a lot of things.. does it increase with engine speed? is it "loud"? Get your ear down there as close as you SAFELY can & try to localize it better.

Broken engine mount maybe?

RE: Thumping Sound

A busted engine mount *might* be the cause.. grab hold of the engine as well as you can while it's idling & see if that makes the thump stop.

Is it a metallic sounding thump or more muffled? Is the belt in good condition?
