Break Off thread from -- Compressor clunking / rattling while running: need diagnostic / repair help

[firemedic1015]

Ok compressor experts, I’m having a similar problem with my Bauer Utilus. Do you think the sound in this video is from the valves also? I took a look with a borescope and there is nothing bouncing around loose in the crankcase…

I really don't hear any knocking.....
I hear a tick every now and then.
Seems like the belt jumps at the same time.... is the belt coming apart or the shield hitting something?

I'm not there and just listening to a video but I am hearing what sounds like belt slap. I would check your tension and inspect the entire length for a tail or separation.
