1. it's more like 1.5 times.
2. "service life of the engine" is the whole point of going back to 
chains - "uneconomic to repair" means new car.  belts keep an engine 
going as long as it'll run.  chains, especially long run chains on 
overhead cams, turn the engine into an inefficient, polluting p.o.s.
