Its intermittent so I cant record the sound.
It basically happens after firing the car up on ignintion , as per normal, the rev counter goes up and then begins to drop.
Now occassionaly, on this drop there is a faint clunk.
Primarily happens on cold starts, but has known to happen, after the car has been off for say an hour or two after driving and then upon restarting.
The noise is coming from engine bay area.
Any questions please ask.
What could this be?
Just had full inspection two about two months ago.
