if you took it to a dealership they would possibly fit a new engine, "using a different garage" as they mostly have college lads who no nowt about how a car works but who can do services brakes and suspension and change tyres
its all about the money, they dont want your car clogging up there garage for days on end why it takes 12 of them to put an engine in that could have done 40 services in the mean time.
show a dealership so called mechanic a 20 year old car with proper rusted rounded bolts etc they would cry at the thought
its all in the technic which they dont teach you at college
