Is this normal? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I just finished installing the perrin pulley and afe intake. But I'm hearing this "tock-tock-tock-tock". In the video the sound will change during the first 4-5 sec of the vid also you will hear a vibrating sound at 34-35sec . OR am I just being paranoid?

Thanks in advance, hopefully I'm just paranoid and my engine isnt about to explode.

I'm no expert so this would just be an opinion, sounds like a vibration... I'd almost put the stock pulley back on and see if it goes away, a lot of work but better than shaking your engine appart (if that is what it sounds like).

perhaps something is not tightened right?

I didnt torque the pulley to spec when i did it the first time, made a similar noise. snagged a torque wrench and the sound stopped. do that before you damage the car.
