Crankshaft and Camshaft: What They Do and When to See a Mechanic

Your engine relies on precise timing to run smoothly. Since both the crankshaft and camshaft play a major role in engine performance, any issues with these parts can lead to serious problems. Whether you’re commuting through Cedar Park or taking your kids to spring break camp, keeping your engine in top shape ensures a smooth and reliable ride. At Meineke in Cedar Park, our ASE-certified mechanics specialize in diagnosing and repairing crankshaft and camshaft issues thus keeping your vehicle running its best. So, in this post the experts at Meineke are here to help you learn everything you need to know about your crankshaft and camshaft.

What Is a Crankshaft?

The crankshaft is one of the most important components in your engine. Since it converts the up-and-down motion of the pistons into rotational power, it allows your car’s wheels to turn. Located at the bottom of the engine block, the crankshaft connects to the pistons and flywheel, thus ensuring that power transfers smoothly from the engine to the transmission.

What Is a Camshaft?

The camshaft works in sync with the crankshaft to control valve timing. Since it regulates when the engine’s intake and exhaust valves open and close, it ensures the right amount of air and fuel enters the combustion chamber. Most modern engines use a timing belt or timing chain to connect the camshaft to the crankshaft, thus keeping their movements perfectly synchronized.

How Do the Crankshaft and Camshaft Work Together?

Since the crankshaft and camshaft are connected, they must work in perfect harmony. The crankshaft powers the rotation of the camshaft, which then operates the valves. This precise movement ensures that fuel enters the cylinders, then combustion occurs, and exhaust gases exit the engine. But if the timing between these parts is off, the engine may misfire, lose power, or even fail completely.

When to See a Mechanic for Crankshaft or Camshaft Issues

Although crankshafts and camshafts are built to last, wear and tear can lead to problems. If you notice any of these warning signs, then visit Meineke in Cedar Park for an inspection:

• Check Engine Light Is On – Since crankshaft and camshaft sensors monitor engine timing, any failure can trigger the check engine light.
• Rough Idling or Stalling – If your car shakes at idle or stalls unexpectedly, then a camshaft issue may be preventing proper valve timing.
• Loss of Power or Misfires – Since timing problems disrupt combustion, you may experience sluggish acceleration or misfiring cylinders.
• Unusual Engine Noises – If you hear ticking, knocking, or grinding sounds, then the crankshaft or camshaft may be worn or damaged.
• Oil Leaks Near the Timing Belt or Chain – Since these components require lubrication, oil leaks can cause premature wear and failure.
