Hi,
My gf's 96 Sentra has been making a clacking sound at idle, at all rpm's. It drives fine. No clacking when in gear. Her mech has "no clue" what the sound is. Anyone have an idea? Belts, maybe? Waterpump ?
Thanks
Timing chain tensioner causing slack in the chain possibly.

I had a '95 Altima that did that. My first thought was the timing chain, but it turned out to be the disintegrating accessory belt zinging around the pulleys. How long has it been since you changed the belts?
Good question. I asked the gf (it's her car) and she says she doesn't know, may have never changed them. With the old V belts, a drop of water on the friction side of the belt would quiet them down for a few seconds. I'll try that with this flat belt. Maybe it will indicate something. Thanks for the idea.
Clacking at "idle at all rpms" ?? What does that mean?
In Neutral, at any rpm, it clacks. It clacks at high idle and low idle. With foot on gas, and off gas.
And not when in drive ? That's odd. Is it a stick or auto ?
Auto.
Let me know what it was if you ever get it fixed
