If you're hearing strange noises coming from your engine or notice that your car is no longer running smoothly, you may have engine timing problems. If your cam timing is off, you'll probably know because your engine will be running extremely poorly ‐ if it even runs at all.

Cam timing is the more critically important type of engine timing. If your cam timing is off by even a little bit, you could be looking at complex engine repair. This is because cam timing regulates when the engine valves open and close in relationship to the position of the pistons. In interference engines (an engine where the pistons and valves occupy the same space just milliseconds apart) incorrect timing results in contact between the valves and pistons.

An engine misfire occurs when an engine cylinder fails to properly combust the air-fuel mixture inside it. Engine misfires can cause your engine to stumble, rough idle, and feel sluggish. While there are multiple potential causes for an engine to misfire, one possibility is that the cam timing is off. This disrupts the combustion process by opening or closing the valves prematurely.

As long as they're lubricated with motor oil like the rest of your engine, timing chains should last the lifetime of your vehicle. However, a timing chain that does not maintain the proper tension may break, or other damaged engine components can cause trouble. You may have a timing issue if you notice one of these two bad timing symptoms.

Engine knocking or pinging occurs due to "pre-ignition." This is when the fuel in a cylinder prematurely combusts and fires against a piston that is still attempting to compress the air-fuel mixture. The knocking sound may sound light and metallic and usually occurs during acceleration.

Ignition timing, on the other hand, is more about when the spark occurs to begin the combustion process. To power an internal combustion engine, each engine cylinder cycles between four stages: air-fuel intake, compression, ignition, and exhaust. Ignition timing refers to this third stage ‐ the moment when the spark plugs ignite the air-fuel mixture to create combustion. Your ignition timing is off when the spark plugs either ignite the fuel too early or too late. The result is rough idling, a loss of engine power, and overall lower fuel economy.

Your engine is a powerful piece of machinery. Pistons, rods, and other critical parts must work in harmony to deliver reliable engine performance. But if your engine timing is off, your engine's performance can suffer and you could have a costly repair. Here's what you need to know about engine timing.

So, how does your engine know how to keep the opening and closing of valves, the rotation of the crankshaft and camshaft, and every other complex part in sync? That's where your timing chain comes in. A timing chain is powered by your engine's crankshaft and spins the camshaft, which regulates valve timing. A timing chain is a metal chain, similar to a bicycle chain, that is built directly into the engine.

Engine timing refers to the synchronized motion of rapidly moving engine parts. In order to function properly, an engine needs to have extremely precise timing between the movement of its pistons and valves (known as cam timing) as well as when it ignites the air-fuel mixture in its cylinders (known as ignition timing).
