You could skip the making the engine parts phase by going to village close to the lava, use a pick axe and destroy the cars to get the parts as well as other drops, this includes cars and busses so far as I know. The merchant there also sells the parts for 500 gold coins each If you don't know where this village is and you don't mind spoilers click here --> There is a full map in the guides section use that to locate the small lava circle
