The 2017 Mitsubishi Mirage utilizes a timing chain to connect the crankshaft with the dual overhead camshafts. Proper alignment of these shafts is crucial for managing the variable valve timing. The camshaft is made up of lobes that control the opening and closing of intake and exhaust valves, regulating the flow of air and fuel into the combustion chamber and allowing the escape of exhaust gases. Typically, with regular maintenance, the timing chain can outlast the vehicle itself. Enclosed within the engine, the chain is continuously lubricated during operation. However, low engine oil levels or degraded oil quality can potentially harm the timing chain and gears.
