An internal combustion engine features thousands of moving parts, so potential issues can start anywhere. However, some problems are more common than others, and a little preventative maintenance can go a long way toward avoiding extensive engine repairs. Below are a few of the most common issues you might run into.

What Are Common Engine Problems? 

1. Worn Spark Plugs

The spark plugs deliver an electrical spark that ignites the gas inside the combustion chamber. These components wear out over time, eventually becoming too weak to ignite the fuel or causing the substance to combust too late. Misfires and timing issues can damage the pistons and other important engine components, so have the spark plugs checked if your car suddenly loses power.

2. Poor Compression

If your vehicle loses power, struggles to start, or has poor gas mileage, your engine may not be generating enough compression to power the pistons. Poor compression can be caused by a variety of issues, including broken valve seals and worn-out piston rings, which keep gas from leaking out of the cylinder. Most of these issues are the result of normal wear and tear and can be corrected by a skilled engine repair technician.

3. Inadequate Lubrication

Oil is the lifeblood of your engine, dispelling heat and reducing friction that can quickly wear down vital components. As it ages, oil becomes thicker and clogged with particulates. Changing the substance every 3,000 miles or every three months is the best way to keep the engine running perfectly and prevent breakdowns.
