A weird clicking noise after changing the supercharger oil and belts

Sarithis · 05-25-2022, 05:57 PM

A few weeks ago I left my Z at a professional service station. They replaced the engine oil, Stillen supercharger oil (Vortech V-3) and one of the belts (the longer one). After receiving the car, everything seemed to be okay, however, when I came back home, I noticed a very loud clicking noise. Its frequency was correlated with RPMs and it was coming from the supercharger area. I've been driving like that for the past 2 weeks and so far everything seems fine, but the noise is extremely annoying. Something is clearly wrong. Do you have any suggestions based on the attached video? I've already checked both belts - the tension feels right and there are no cracks or bruises. I'd be really grateful if you could listen to it and let me know what you think. The service station is a few hundred kilometres away, which is why I'm asking here instead of going there again. Maybe it's something common.

The video doesn't do it justice - the noise is so loud that I can clearly hear it while sitting inside.
I marked the area where it seems to be coming from:
