Hi, I'm at a crossroads. I have a 58 plate insignia 2.0CDTI SRI 160 BHP. The bottom end is rattling, its just have waterpump, timing belt, all new rockers, oil pick up seal, oil filter replaced. Can the crank be worked on from underneath without taking engine out?? Or if get offered good price, then she can go. I'm gutted. Help please
