3l v6 (asn) and serpentine belt. The belt comes off if accelerate hard. The problem started when the ac compressor got stuck and broke the old belt. The current one is 6x1880, but I read that the oem is 6x1878. Could this be the fault? Now I have changed the belt tensioner, alternator and ac compressor. The belt rotates directly and does not resonate.

Hi. I fixed the cylinder head and found this under the car. I couldn't find where it could have dripped. Where is this from or is it even from that car. 1.8tfsi (cabb)
