When working with mechanical structures like cars, there are many sounds that you may question over time. While it might be difficult for you to immediately identify the issue, there are ways that you can determine when the problem at hand is actually camshaft grinding rather than something else. Camshaft grinding occurs when the arc of contact between the camshaft lobe and the wheel changes. This change is continuous as the flanks, base circle, and nose are on the ground. When this occurs, wheel-work contact length and material removal rates must be changed immediately. Let's delve into the signs that the sound you hear is actually camshaft grinding.

1. Ticking or Tapping

Not all sounds can be traced back to the same source when it comes to mechanical failures. If the sound is deep and low or resembles a groaning, it's probably not a matter of camshaft grinding. Rather, camshaft grinding typically can be traced back to a ticking or tapping sound. These sounds are often intermittent, which can make them a bit difficult to catch, so when you do notice them, have them inspected as quickly as possible.

2. Metal Debris

Check your machine's engine oil periodically. Often, this can reveal the true problems within your machine. Typically, a worn camshaft lobe is accompanied by metal debris in the engine oil. The metal may not be immediately apparent on the dipstick, but it can be seen when the oil is swirled. To prevent this issue, have your oil tank inspected every time you go to change your oil. You'll know it's time to do so when your car alerts you of low oil levels.

3. Cylinder Misfires

Often, a cylinder misfire may accompany a camshaft malfunctioning. This could result in a jerking or shaking of the vehicle or unnatural fuel consumption and engine emissions. Keep an eye out for any lurching in your vehicle as most models today handle so well that such movements likely indicate a problem. Different cars may also have a different number of cylinders. For example, according to LiveAbout, a four-cylinder SOHC engine will have one, yet a V6 or V8 will have two. Regardless, you can never go wrong with having a professional take a look under the hood if you are unsure about whether there is an issue.

4. The Check Engine Light Is On

This is one of the most obvious signs that your vehicle is experiencing camshaft grinding. Your check engine light will typically turn on when this occurs. Of course, warning lights can be triggered by multiple issues, so further investigation may be helpful to discern the issue. Get into the habit of taking action anytime you see this light come on in your vehicle.

Staying on top of your car's maintenance can save you money on extensive repairs in the long run. If they aren't addressed quickly, you may regret it later on. Contact Effingham Regrinding Inc. if you're experiencing issues with your camshaft.
