Hi Rusty, thanks for the reply. The car has done only 7,500 miles and cost £670, body work is rust free and wax oiled from new. The original owner had engine problems from new which meant it was left for a number of years unused. The last owner replaced the engine with a used unit of unknown mileage, which i think is causing the problems. The gears are really smooth, no problems there. My other half wants to know if there is a balance shaft in the engine? Many thanks Bolly x
