you shouldnt have filled it in an angle, its never going to be right...

I got the hose in the hole, then dropped rhe car back down on its wheels so it is level, THEN i filled it from the 17mm bolt, rather than Bens idea of the vss simply because im lazy...

I filled about 2.3 bottles and it started seeping out consistantly in a little stream, by the time it stopped i had a puddle of oil on my garage floor about 70cm in diameter...
