There are many parts in an Acura engine. The main parts are a block, a cylinder head, cylinders, and pistons. Others include a crankshaft, camshaft, valves, valve covers, spark plugs, and an oil sump, also called an oil pan, used to hold the motor oil that lubricates everything.

Each part has a different job, too. Your cylinder head helps keep gas and oil from leaking. Intake valves regulate your engine's air-to-fuel ratio. Exhaust valves regulate the engine's fume levels. Your valve covers help protect engine valves. The camshaft helps make sure all valves synchronize. Pistons pressurize the engine's gas and oxygen. Spark plugs ignite the above-mentioned combo of oxygen and gas, which produce power as they burn. Your crankshaft turns the power into rotary motion. Your drive shaft uses the rotary motion to turn your wheels and spin your tires. The same goes for your transmission.

Many other engine parts are responsible for proper fitment. If any wear out, however, engine trouble almost certainly follows. Luckily, there are signs you can keep an eye out for. Look for the following:

• Trouble accelerating and with idling
• Worsening fuel efficiency
• Stalling out
• Being unable to start your Acura at all

Seeing any? Do a thorough inspection. It'll help you determine what's causing them.
