Volvo Penta Engine noise

[Donald]

I hear a faint ticking or chirping sound. Not sure what it is.

I touched a mechanics stethoscope to raw water pump, PS pump, alternator and idler and tensioner. Did not hear ticking or chirping sound.

The tensioner seemed to have a rougher bearing sound that the idler. I would have thought they would both sound similar. Maybe replace tensioner.

I have a short video but cannot get it uploaded as it's too large or wrong format or both

First off nice video.. can actually hear sound. (not sarcasm)

sounds like some sort of belt or pulley noise to me. Good luck.

sounds like a rough bearing. Trouble with them is the"while you're in theres"

It’s not crank speed or cam speed. Definitely belt drive noise. I would suspect the belt because it is a very low frequency. Greasy or contaminated spot on the belt would be my guess.
