If you know what those early signs usually mean, you are much more likely to fix the small stuff before it snowballs into major engine damage and a big repair bill. Why Modern Engines Still Develop Problems Modern engines are built better than ever, but they work harder than many people realize. Tight tolerances, turbochargers, direct injection, and stop-and-go traffic all add stress. Fluids age, rubber seals shrink, carbon builds up, and heat cycles slowly wear parts out. The good news is that most of the common failures follow patterns. When we see engines come into the bay with big issues, there are usually clues that were present weeks or months earlier. Paying attention to those clues is half the battle. 1. Overheating and Cooling System Failures Overheating is one of the fastest ways to ru ... read more
