I recently bought a used car that seemed fit and well. The engine started easily, ran smoothly and performed well. But after a short while, it developed a whole lot of engine problems. Why might have caused that? -- Darius
Engines wear out, but usually very gradually and only one thing at a time. If lots of things are going wrong almost simultaneously then the engine has probably been pre-damaged – most likely by severe overheating at some point. Odd noises and/or a smoky exhaust are usually clues.
