Car: Volvo C30 t5 2009
Hey, I recently replaced a broken sunroof, and bought a used one off of Ebay. I noticed it had a small gap in the seal, i'm assuming it's for the water draining system but i'm not sure the orientation nor if there's even supposed to be a gap. I believe this replacement sunroof is leaking onto my visor as well causing it to sag.. how is that possible if it's supposed to prevent that via the draining system? Would this mean I have to reseal the liner? Any tips or recommendations or general knowledge

Thanks!
