Breaking in a new vehicle is really about the engine. The break-in — or mechanical run-in — period is designed to begin to wear the engine evenly and smoothly with low, consistent pressure, normal operating temperature and smoothly flowing oil. The goal is to get the engine's piston rings, which expand, contract and flex, to seat properly on the cylinder walls.

The new research center will house not only historical documents related to the ninja, but also hundreds of novels, movies and cartoons that have helped to forge the modern image of the black-clad assassin. … [Read more...] about Research Center Seeks to Separate Ninja Fact From Fiction
