Default 92- LS400 weird engine sound.

Hey!

Yesterday i noticed weird, kind of ticking sound from the engine.

Any idea what might cause it? Timing belt has been changed 52000 miles ago, and the sound does not change much with rpm. Sounds like some bearing is breaking down to me, what do you guys think?

Take the accessory belt off and start the car to rule out or confirm if it's one of the pulleys.

Sounds like a bearing for tensioner or something the serpentine belt runs on. Sounds like a nice exhaust leak too some place.

Need to check the serpentine belt tomorrow. About the exhaust sound, it does not leak, just re-built exhaust with only rear mufflers.
