8 Signs and Symptoms of Engine Damage

The engine is the heart of your vehicle, giving your car the necessary power it needs to operate correctly. When the engine is damaged, it will significantly affect your car’s performance. Fortunately, you can save yourself time and money by quickly diagnosing engine problems before they cause more harm to your vehicle. 

1. The Check Engine light turns on.

Dashboard warning lights are your car’s way of alerting you about problems it detects via its On-Board Diagnostics (OBD) system. If your Check Engine Light (CEL) turns on, you should not dismiss it, as ignoring the problem could cause more damage to your engine (and other parts) over time. There are many different things that can trigger a check engine warning light. Some common reasons for a check engine light appearing include:

  • The Oxygen Sensor needs replacing.
  • The Mass-Airflow Sensor is in need of replacement.
  • The catalytic converter is damaged and in need of replacement.
  • The spark plugs are damaged or worn (causing engine misfires).
  • The fuel cap isn’t on tight enough (a very common, easy to fix issue).
  • many other electronic sensor and actuator related issues

2. Your car is making strange noises.

A knocking noise coming from your bonnet is a classic sign of a dying engine. This noise could be caused by wear of damage to your engine’s mechanical parts such as pistons, bearings or other moving parts. If you hear this type of noise, you should take your car to a mechanic as soon as possible to prevent further damage. Ignoring this problem could result in your car breaking down on the side of the road and a much greater repair bill (than catching the problem early).

Other noises you should look out for include popping, spitting and backfiring from your exhaust.

 

3. The engine is running roughly or inconsistently.

Listen to the sound your engine produces while you are driving. Is it consistent? A struggling engine will often stutter, shake or lose power as the revs increase. A few common solutions for this may be to replace the spark plugs, test / replace your ignition coils, check your fuel pressure, clean your Air Flow Meter or give your engine a tune-up.

 

4. Your car produces oil patches.

If you notice puddles of oil under your vehicle, this is probably a result of a leak in your engine. As the oil depletes, more friction and will occur in your engine, generating excess heat. Oil leaks are common from engine oil seals, and sump plugs / sump plug washers. This can cause damage to engine components over time. We recommend that you get engine leaks sealed as soon as possible.

 

5. You can smell odours from inside the car.

The smell of a car’s emissions should never be noticeable from inside the vehicle. If you have a strong exhaust smell, of engine fumes or any other strange odours, this could be a sign of engine damage. Don’t ignore strange engine smells and expect them to go away. Get your vehicle checked so that the problem can be diagnosed.

6. Your car is using more gas than normal.

 

Increased fuel consumption can often be related to a fault in the way your engine processes fuel. when paired with a visible check engine light and other engine-related symptoms, the problem can be much more serious.

If you notice your car is using more fuel, get it checked and fixed by a professional. This will save you money in the long run.

 

7. You experience a loss of engine power.

Engines will struggle to run at their usual level if there is an internal problem. Your vehicle may stall, shake at high speeds or struggle with hills. If your engine isn’t working as well as it used to, get it checked by a mechanic.

 

8. There is smoke coming from your exhaust.

 

There are several reasons why your exhaust could be producing smoke. The color of the smoke can give you an idea of what is causing the problem.

If the smoke is black, it means that your engine is has incomplete combustion which leads to burning too much fuel. This could be due to:

  • Damaged fuel injectors.
  • Malfunctioning sensors.
  • A damaged air filter.
  • A clogged fuel return line.
  • Mechanical damage in the engine

Grey smoke can mean several different things, making it difficult to diagnose. Possible reasons include:

  • A stuck PCV valve.
  • Problems with your transmission fluid.
  • Excessive oil consumption.

Dark blue smoke means that your engine is burning oil. This is due to oil leaking into your engine’s combustion chamber. This can be caused by:

  • Worn out piston rings.
  • Damaged valve seals.
  • Other worn or damaged engine components.

HOW TO GET RID OF A MUSTY SMELL IN YOUR AC

Your car can work perfect mechanically, but it can be virtually undrivable if the cabin smells bad. That may be due to things like spilled milk or takeout containers with bad food in them, but often it’s because the heating, ventilation, and AC system has become contaminated. The musty smell is extremely off-putting and can even make you sick if it’s left untreated.

Correcting a musty AC smell often costs under $200 as a DIY job, or it could be two to three times that much if you take it to a mechanic. Here’s what causes the smell, ways to eliminate the odor, and how to prevent it in the future.

UNDERSTANDING THE MUSTY SMELL

DIY CLEANING TECHNIQUES

Follow these steps to rid your car’s AC system of musty odors:

  • Replace the Cabin Air Filter – If the filter is dirty or clogged, replace it with a new one. And if you have a musty smell, don’t count on only visual confirmation that it’s dirty. Swap it out.
  • Use an AC System Cleaner – Treat your HVAC system with a high-quality, highly rated AC system cleaner. Follow the instructions on the product.
  • Let Your Car Sit – Wait the specified time on the product before you use your car. The treatment time varies, and often, the longer it sits, the better the treatment result.
  • Perform a Follow-Up Treatment – For stubborn odors or extreme buildup, you might have to perform a subsequent treatment.

In addition to specialized products, you can use common household items for a DIY approach:

  • Vinegar – Mix equal parts water and vinegar and spray it into the air intake vents.
  • Baking Soda – Place an open box of baking soda in your car overnight to absorb odors.
  • Sunlight – Leave your car in direct sunlight with windows slightly open to help dry out moisture and prevent mold growth.

One of the first steps in tackling a musty smell in your car’s air conditioning (AC) system is understanding its root causes. Musty odors often stem from the growth of mold, mildew, or bacteria in the AC system. The dark and damp environment within the AC unit provides an ideal breeding ground for these unpleasant elements.

Common causes include:

  • Accumulated moisture in the evaporator core.
  • Clogged or dirty cabin air filters.
  • Bacteria or mold growth in the cabin air intake and other AC components.

Aside from the obvious discomfort of driving in a car with a musty smell, there are more serious reasons to address the issue promptly. Mold and bacteria can not only compromise the air quality inside your vehicle but may also have negative effects on your health, especially if you suffer from allergies or respiratory issues like asthma. A musty smell that isn’t dealt with can lead to potential damage to your AC system, contributing to more extensive and costly repairs down the road.

 

PREVENTIVE MAINTENANCE TIPS

To maintain a fresh-smelling car and keep it fresh, incorporate these measures into your routine:

  • Run the AC Regularly – Turn on your AC periodically, even in cooler weather, to prevent moisture buildup.
  • Keep the Cabin Clean – Regularly clean the interior of your car, removing any potential sources of odors.
  • Avoid Eating in the Car – Food crumbs and spills can contribute to unpleasant odors.
  • Use Air Fresheners – Place a long-lasting air freshener in your car to maintain a pleasant scent.
