[Tigers] Metallic chatter noise

"Clatter gets worse as rpms increase but as I reach cruising speed the 
clatter seems to go away, although exhaust might be drowning it out. If I 
slow down and accelerate again it gets worse again."

Could come from many sources, a lot that you already mention. The thing that 
I come back to those is the comment above. As the engine accelerates the 
engine torques in its mounts. Over time the mounts can compress or tear. I'd 
still be incline to check the fan to shroud (or fan to anything else, my 
recollection is it comes close to the rack).

Hi

Been a while since I posted, but having a problem. I hope the attached 10 
sec video goes through.

Getting a metallic clatter from front of the engine.

I can not see anything making contact.

The fan, fan pulley and shroud are secure.

With a stethoscope I checked for internal clatter at the water pump, timing 
cover, generator and valve covers. All internals sounded to be running 
smoothly.

Clatter gets worse as rpms increase but as I reach cruising speed the 
clatter seems to go away, although exhaust might be drowning it out. If I 
slow down and accelerate again it gets worse again.








Thanks

Jim
