Engine remanufacturing professionals must follow a Code of Practice when working on engines to create a product that is as good as new. We find out what’s involved in remanufacturing at AMAC Engineering Ltd. Plus, we start a short project on a 2004 Ford Focus ST170; strip down the original 80k engine on our project Toyota Aygo to see why it was smoking; look at the Honda CR-V Mk2 and Mk3 as a used car prospect; service a 1.2 PureTech 3-cylinder engine found in many Citroën and Peugeot cars; fit an uprated rear anti-roll bar to a Porsche Cayman and look at how torque wrenches work.
