Why does My Car Engine Knock

According to the mechanic, there are a few things that can cause your car’s engine to knock. In this article, we’ll go over the most common reasons and how you can fix them.

Causes of Knock

Knocking is the sound a car engine makes when it misfires. It’s caused by debris or gas getting into the engine, and it can usually be fixed with a tune-up. Here are some other common causes of knock:

– Dirty air filters: Cleaning them regularly can prevent knock.
– Corrosion on the fuel injectors: If this isn’t treated, it can cause knock.
– Faulty spark plugs: Replacing them regularly can help prevent knock.
– Damaged valve springs: If these are replaced, it can usually fix knock.

How to Fix Knock

Knocking or knocking noises coming from your engine are usually indicative of a problem. Here are some of the most common causes and how to fix them:

1. Piston knock: This is the most common type of engine knocking and is caused by a worn or broken piston ring. A qualified mechanic can replace the piston ring and fix the knock.

2. Valve knock: This is caused by defective valves, which can range from small problems like burrs on the valves to bigger issues like worn valve guides. A qualified mechanic can replace the valves and fix the knock.

3. Cylinder knock: This is caused by a loose or damaged crankcase bearing, either from age or wear and tear. A qualified mechanic can replace the bearing and fix the knock.

Conclusion

There are a few things you can do to try and determine the root of your car engine knock. If you have recently installed new exhaust, components, or emissions upgrades, it’s possible that these changes may be causing your engine to knock. In addition, if you have altered your suspension settings or changed the way your tires are mounted, this could also be causing the knocking. Finally, if you hear knocking coming from both sides of the engine at once, this might mean that there is something wrong with one or more of your pistons.
