Car was really tidy, went round it a few times, oil was a touch low but all looked good, started it up had a slight knock and wasn't happy with it, took it out for a test drive, no boost at all? Felt like a 20l sport, and brakes were shocking, got back and opened the bonnet again, and the remainder of the oil was pouring out from around the front crank seal area, down onto the exhaust manifold.
