Your Toyota MR2 engine has lots of parts. Its main parts are a block, a cylinder head, and cylinders. Just about every cylinder has a piston. Every engine, Toyota or otherwise, has valves, too, along with a valve cover, spark plugs, and other parts, like a camshaft and crankshaft. There's even a separate sump or pan that stores motor oil. Each of the parts of an MR2 engine does something different as well. The valves, valve covers, and cylinder head, for example, seal the engine. There are two kinds of valves: intake and exhaust. Intake valves balance the air and fuel the engine burns to make power. Exhaust valves manage exhaust fumes. Valve covers safeguard valves, and the cylinder head both keeps gas from escaping and prevents oil leaks. Camshafts, however, regulate the activity of valves. Engine pistons compress the engine's gas and oxygen as they pump, making more energy available. Spark plugs ignite that mix, and it combusts, producing power. Crankshafts transform power into rotary motion, which drive shafts and transmissions use to turn wheels and tires. Many other components, from gears and sprockets to rings and bearings, fit everything together correctly. If any wear out, though, engine problems are sure to follow.
