By the way how easy are timing belt changes? It looks as if the belt goes around the o/s engine mount Is this the case? Just did the handbrake test no joy, I didn't stall it but it would have done if I'd pushed it over the edge Thing is, I don't think a faulty tacho would explain the higher fuel consumption I'll see how it goes over the next few days, could just be that a bottle of STP Fuel Treatment is all that it needs
