Default 2000 NB1 Rattling during idle after timing belt

https://imgur.com/a/nifUxFS

I completed my timing belt change and the car fired right up. After a little bit there was an intermittent rattle which sounds like it is coming from the alternator but I don’t see any movement from the alternator or any of the other pulleys. I checked the alternator tensioner and the locking bolt and both were firm/ tight.

The rattle only happens during idle and I can make it happen more or less when I hold the window switches or if I turn on the headlights.

The car has an MS3 and I ran a log during idle but there was no knock reported from knock in or from the individual cylinders either.

Any ideas?

Loose crank pulley is my guess.

Thanks I double checked the torque on the pulleys and everything was good. Turned out my alternator belt was way loose. Got a kriket gauge and set it up around 110lbs.
