soft "clack" sound at 40km/h
Anybody else hear this?
I encounter this every morning: I start a cold engine and I let it go through the warm up idle. Then when I drive off I hear a soft "clack" from the engine bay when the speedo crosses -40km/h (25mph). I don't hear the clack for the rest of the drive.
What is happening? Apologies if this has been discussed before.
