think there's a decent engine place called halesowen engines there not too far from junction three of the m5 head towards halesowen down the dual carriageway then take a right at the first island you come to, you then come to a set of lights keep in the left hand lane and start to follow the road round to the right and there on your left opp macdonalds
We used to have engines worked on by them at my old work dont know how much they charge but there work is good.
