I�m going to get so help from my minions to test while I listen.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all... 2001, 996 Cab with about 134K miles. Engine runs strong, good compressions. On every other engine shutdown or so, I get an unusual clicking noise. Just wondering if anyone else has heard something like this. I have a short video where you can hear it. It's a click right as the engine stops. Not sure if it's a problem or not so tossing it up here for some opinions.
Any ideas? Thanks in advance!
Video of shutdown noise:

So tried a few times and there does not seem to be a correlation to clutch in and the noise. I experienced it at least once with the clutch in, but I'll test it again after the car has been driven harder. I couldn't get it to reliably make the noise clutch in or out.
It's factory exhaust with a Fister mod. Doesn't sound like the usual kind of pings you get from an exhaust system. Plus, when it does occur, it always happens right at shutdown.
Darn. Some of us get a little drivetrain rattle on shutdown. However, with the clutch disengaged it goes away. In my case it's a 100% correlation. It shouldn't really matter how the car is driven beforehand. Best of luck - this was my only experience or semblance of wisdom I had to share, unfortunately.
Could be a belt tensioner too. The key is to figure out if it�s internal or outside the engine. If it�s internal it could be �chain slap� (bad tensioner bleeding down as the oil pressure drops)... that wouldn�t be good...
Yes, get someone underneath to try and locate the noise.
It‘s loud so it shouldn’t take too long to locate.
Use a long screwdriver to feel for vibration.
Anything that loud has to also vibrate.
A screwdriver will keep you(or your helper) from getting burned.
