What happens if you make a mistake while installing a camshaft in a car engine?! 🚗⚙️ Inside the cylinder head of your engine, the camshaft is responsible for opening and closing the intake and exhaust valves at the exact right moment. When a mechanic installs a new set of camshafts, the heavy-duty metal gears must perfectly mesh together to keep the engine in time. This installation requires absolute, terrifying precision. If the mechanic accidentally installs the camshaft just one single gear tooth off, the engine timing will be completely ruined. In an interference engine, this means the heavy metal pistons will violently smash directly into the open valves the second you try to start the car, requiring a massive and incredibly expensive rebuild!
