I found a very weird screw sitting between the middle two headers (stock exhaust manifold) going through the exhaust gasket and into the block. The bolt was very unscrewed, there were about 3-4mm between the head of the bolt and the gasket. The gasket had a mark on it around the screw, but bigger than the head of the screw (like a washer was there at some point). I took the screw off and a bit of oil came out. I put a washer and tightened it up. But I was wondering if anyone knows what it's for. I figured it was just to hold the gasket tightly, but then why did oil come out of the other side?! The screw cap was a 9mm, the screw was very thick (M6 or M7 I guess) and it wasn't very long, around 15 mm I'd say.
