Well that wasn't the day I'd planned. Went to chat cars at my brothers as normal for a Sunday, mate of mine said mine sounded quite good. As I hadn't heard it I threw him the keys. It sounded really good until he pulled up again and I spotted the trail of oil. Upon investigation the seal has failed for the modene. Saddly it looks like somebody has changed it before but pinched the seal wrecking it and bodging it with instant gasket. Looks like I'm getting a lift home now and will have to pick a new seal up tomorrow. Thank goodness for the company car.
