The 5 Most Common Honda L15B7 1.5 Turbo Problems

Can I drive my car comfortably with the engine of the Honda 1.5 Turbo? If not then, what issues will I be facing

1. Having A Problem Of Over-Dilution Of Oil With Fuel Is Major

At first, the problem of over-dilution can be a real struggle.

Even if you do not know anything about your engine, this is one issue that will leave you more concerned than ever.

Over-Dilution And What It Means

Essentially, you first need to know what over-dilution even means in Honda engine terms. The real definition of the term is the apparent increase in oil levels in the engine.

There is a sudden increase in the oil level in the motor, which can come as a bit of a shock, especially if you know that you haven’t put more oil in the motor itself.

You can imagine how dangerous this might be for the rest of the vehicle.

Figuring Out How It Happened

You might be thinking to yourself, “Maybe I put too much oil in my engine.”

Oh no, this isn’t because you filled it up too much; rather, it simply exists as an issue because fuel from the rest of the car is leaking into the engine.

Often you wouldn’t even notice such a thing if it weren’t for the apparent smell wafting around your car and inside.

The best ways to find out if you have oil dilution is:

  • Look for any visible signs of oil levels rising.
  • Make sure that your car does not reek of the smell of fuel.
  • Noticing symptoms such as power loss, misfire, limp mode, etc., within the motor itself.

Ways To Solve It

The use of software updates was probably the best way to tackle this issue from the beginning. Alongside that, the company also offered extended warranties.

2. Carbon Buildup Is Such An Issue In Many Motors

Something that makes the Honda engine suffer is the carbon buildup that has become so prominent. The buildup itself is complicated, which makes it even tougher to deal with.

The Carbon Buildup Issue

So what exactly is this carbon buildup?

Is it something that you can simply ignore? Carbon buildup means exactly what it sounds like.

The byproduct of burning so much fuel within the vehicle will affect the general setting of the motor.

That byproduct is the buildup found on the intake valves, the injector nozzles, the combustion chambers, etc. This procedure happening is more natural than you would believe.

Carbon buildup is dangerous because:

  • It has a massive impact on how the engine works.
  • You wouldn’t even know there was an issue until the car broke down.
  • Your engine could get seriously damaged without you even knowing it properly.

How Does It Have An Impact?

The buildup of carbon particles has a bigger impact on your engine than you would think. For one, the power of the motor is affected in such a negative way.

Since oil doesn’t pass as well throughout the engine because of this buildup, it can cause the car to lose power suddenly.

The performance is also known to suffer greatly, which is another issue to be talked about.

How To Make It Disappear

Changing the oil frequently might be the answer to this problem. If you change the oil in your car, the odds of having this problem will lessen by themselves.

3. Having Malfunctioning Spark Plugs Is A Big No-No For Your Car

Spark plugs are some of the most complicated things to be a part of your car. They may look small but don’t be fooled because they have a big impact.

Meaning Of Malfunctioning In General

To understand malfunctioning, you would first need to define it. In terms of definition, malfunctioning means the failure of a unit to perform its normal functions correctly.

So in engine terms, something is not acting the right way within the engine, which causes serious damage to the engine.

In this case, the spark plugs are the culprit, and usually, they can be considered the biggest issue within motors.

The Issue With Spark Plugs And How To Fix It

Generally, spark plugs are known to malfunction.

They aren’t made to withstand hard conditions often, so being in a motor that does wear and tear its parts is not the best way for these spark plugs to survive.

The main issue that might be linked is that the Honda 1.5 Turbo engine does not heat up as fast, which has a significant impact on the spark plugs.

The best way to go about actually fixing these issues is to replace your spark plugs every few months.

During this while, make sure to:

  • Not to use your car as often because it can lead to more damage.
  • Seek professional help to get some better care for your car.
  • Find out ways you can maintain your vehicle to prevent the damage that can be done.

Understanding Your Vehicle

You need to be aware of everything in your car. From the smallest change possible to the biggest one, you should understand everything.

This only helps you in making sure you can have the best kind of attention for your vehicle.

4. Your Honda Engine Might Have Some Problems Heating Up

One of the major issues we tend to ignore is one related to heating.

While everyone always talks about overheating, have you ever considered the possibility that your engine may be underheating?

What Does This Heating Do?

The body heat of a car body is something we don’t acknowledge when we first talk about cars. Overheating is often talked about since it does occur in many engines.

However, motor underheating is something that has never been talked about before. The heating of the car is crucial to how well the motor works.

Why Is This Issue One To Be Talked About?

Understanding the issue is important because it helps us understand why the problem is of even any significance.

Heating may not seem like a big thing to you, but it helps the car perform better.

The issue can be seen when:

  • There is a significant decrease in the cabin temperature.
  • The performance of the motor is seriously lacking.
  • You notice the power lessening in the motor itself without explanation.

Fixing The Problem

By the viewing of what others say, the solution to this problem is not exactly very prominent.

When asked, Honda Company was known to give tips to keep the car warm such as constantly driving it.

5. Your Engine Might Start Stalling, Which Can Never Be Good News For You

Lastly, stalling might be the thing first to catch your eye in a bad situation. When the car begins to stall, you know something bad is up in the motor.

Understanding What Stalling Is

Stalling means a sudden movement of stopping the vehicle simply because the motor probably has been overloaded.

This doesn’t always happen because you made some bad decisions, but it can also happen when there is a genuine issue within the motor itself.

That’s why stalling is one of the things you cannot deal with.

Why Does It Impact The Car, And How Can I Fix It?

Stalling makes the car stop all of a sudden. Let’s imagine it stalling in the middle of the street.

That’s not such a pretty sight. The Honda engine can become seriously damaged if it stalls enough times.

To fix this issue, you would need to get your Honda 1.5 Turbo engine serviced. That is probably the best way to go about this issue.

Maintenance is important for all engines, so ensure your engine is maintained frequently enough to avoid the issue.

Why Isn’t That Big Of A Problem

While it may come as a shock, stalling isn’t as big of a problem.

While it can be considered common, the issue is slightly less common as compared to others. So you might not need to worry at all.

If the Honda engine stalls, do make sure to:

  • Move your car to the side to prevent accidents or damage.
  • Consult a professional because you might not know what to do.
  • Relax because nothing bad is happening; it’s just a minor inconvenience.
