hi, just looked under my fiesta rs turbo today and found a puddle of oil under the engine on the drivers side quite close to the front. and also the water level in the header tank rises as i rev the engine? my gearbox has gone and so has my clutch but i doubt its got anything to do wiv that? the internals are fully forged so i doubt i have blown it up and its just had a new turbo?? maybe a head gasket? any other ideas?? cheers
