Can you fix a knocking car engine sound?

I’m sure we’ve talked a lot about all the problems we and those with this passion encounter.

The next question is… can we fix it ourselves? Or do we trust specialized ones to do their jobs on this matter? The answer is straightforward!

It depends on the gravity of the problem that we encounter. For example, we can solve most issues in minutes or hours. 

Does that mean that for every problem that we have, we should try to handle it ourselves first?

The answer is no. Doing that without first having basic knowledge of the matter at hand will be making things worse. The bill will only start growing, making matters worse.

But that’s why you’re here after all. Right? 

You are coming to the right place for the correct information so that we may give you the basics and more.

Below you will find a list of valuable things to watch out for so that you may take good care of your engine.

Regular oil and filters change.

Oil is the first line of defense for preserving the engine components. Its lubrication properties will disperse the heat and withdraw any debris and tiny metals existent in its components.

Reduced risk of engine damageIncreased risk of engine damage
Improved engine performanceDecreased engine performance
Improved fuel economyReduced fuel economy
Reduced maintenance costsIncreased maintenance costs

Although it comes with a great list of benefits, ignoring any check-ups and revisions will make it your greatest enemy instead of your best friend. 

Because of its cleaning properties, not changing the oil in time will create a particle buildup. It eventually results in sludge that will recirculate into the components again and again. At a point, you will pay a visit to the mechanic sooner than you thought.

Usage of higher octane fuel

Low octane fuel types can negatively impact your motor’s performance and durability. As we mentioned before, it will only cost you considerably to repair the damage done to your motor. 

Take a look at the differences between high and low octane fuel.

High Octane FuelLow Octane Fuel
Contains more hydrocarbonsContains fewer hydrocarbons
Higher octane ratingLower octane rating
More expensiveLess expensive
Better engine protectionLower engine protection

Rarely adding octane boosters will improve its rating, potentially making the noises disappear.

Scrub the combustion chamber

You can quickly do it with the help of some great cleaning products. They will remove the excess carbon deposited onto the chamber’s walls. Unfortunately, the buildup often gets in the way of the combustion process. It lowers any power the wheels can receive.

Don’t stress yourself if you find it difficult to follow the procedures online. That’s why you can leave it to your mechanic to do it for you, as it’s neither hard to do nor expensive.

While you’re at it, make sure your car doesn’t smell of smoke or have dents. All these points apply to travel trailers as well.

When I start my car

The first thing we do when we start our cars is to listen to the sound of our motor roaring. When you press the Start button, all the sounds from the motor should be in rhythm. If you start to hear engine knocking noises, the sparks did not ignite the engine correctly.

Poor ignition contact is a consequence of low-quality fuel, malfunctioning sparks, or any of the reasons above. If you mistreat your car’s problem, the motor could be harmed. It only means a faster visit to your nearest repair shop.

Another cause might include a malfunctioning knock sensor. Take a look at the following signs.

Sign #1Poor acceleration
Sign #2Decreased fuel efficiency
Sign #3Abnormal engine noise
Sign #4Engine hesitation
Sign #5Increased exhaust emissions

Avoid spending a fortune on parts replacements. You could prevent all of the causes before doing any harm by using the right fuel octane and suitable motor components. Also, pick up on good driving habits. 

There are a few ways to determine what unfortunate event has descended upon your motor.

What causes the noise?

You should never stop looking for issues to fix if there are any when it comes to hearing engine knocking sounds. 

As we have stated in all of the problems listed above, many things can cause trouble and stop functioning correctly. 

When it comes to the knocking sounds that the motor is making, the first time you hear it is also the first time you should take action.

It is never great to wonder about the meaning of the sounds but to search and eliminate the problem as fast as possible. 

Although you would believe that only the performance would be affected for some time, I suppose you might be wrong. In the long run, taking care of the components will only prolong your engine’s life and enhance its performance and viability.

It includes the:

  • the valves
  • cylinders
  • pistons
  • rods
  • and rings

The consequences are far more significant as you may end up a pedestrian. It could be worse. You could be a pedestrian forced to pay the bills of a no longer usable vehicle.
