9 Warning Signs of Engine Damage

Table of Contents

Has your car been making strange noises or acting up lately? As much as we try to keep up with regular car maintenance, engine issues can sometimes creep up on us without warning. Knowing the signs of potential engine damage is crucial for addressing problems before they escalate into expensive repairs.

An engine is the heart of your vehicle, comprising hundreds of precisely engineered parts working in perfect harmony. When one component starts to fail, it puts unnecessary stress on others as well. 

Left unresolved, minor issues have a way of multiplying into major damage. Rather than ignoring that weird ticking sound or rough idle, pay attention to your car’s subtle clues.

In this blog, we’ll be sharing 9 common warning signs that could indicate an underlying engine problem developing. Don’t underestimate your car’s attempts to communicate with you! Once you know what to look out for, you can proactively diagnose potential issues before they ruin your day—or bank account.

So read on to get familiar with the top signs that your engine might be crying out for some TLC before it’s too late. A little care and attention can save you from much bigger headaches down the road.

1. The ‘Check Engine’ Light Is On

One of the most common signs that something may be wrong under the hood is that the ‘check engine’ light will turn on. As its name implies, this indicator lamp alerts you that your vehicle has detected a fault within its emissions control system. 

While it doesn’t necessarily mean major engine damage has occurred, you’ll want to have the code read as soon as possible so a mechanic can properly diagnose the issue. 

Leaving the light unaddressed allows problems to escalate over time as components wear down more rapidly without proper functioning. Don’t ignore this warning – get it checked out to avoid potential repair bills down the road.

2. High Oil Consumption

If you find yourself needing to top up your engine oil level frequently between scheduled changes, this could point to an underlying problem causing abnormal oil burn-off. Over time, failing to maintain proper oil levels can lead to increased wear of internal engine parts and potentially more damage. 

The rate at which an engine uses oil normally increases with age and mileage, but a young vehicle burning through it unusually quickly is a red flag. 

Have a car mechanic inspect for leaks from gaskets or seals, and also examine components like piston rings that may not be sealing the combustion chamber properly if oil is disappearing too rapidly. 

Dealing with the root cause early can prevent the need for a much more serious engine damage rebuild.

3. High Exhaust Emissions Levels

The gases exiting your vehicle’s tailpipe can also provide clues about engine health. A noticeable increase in exhaust smoke – whether gray, blue, or black – needs investigation. You may also notice changes in how your car runs like reduced power or strange smells if emissions rise above normal. 

Since modern engines rely on precise fuel and air mixtures, any disturbances can damage components over the long haul. 

If your check engine lights or codes relate to emissions, or you suspect an increase based on visible or odour changes, a diagnostic test by a trusted car repair shop can detect exactly where emissions levels have swung high to pinpoint the problem area.

4. Unusual Sounds From Engine

Any new knocking, ticking, grinding, or whirring noises under the hood should raise alarm bells. Our engines produce some normal sounds as parts interact, but abnormal noises could indicate engine damage. 

Location helps diagnose the cause – noises near the top may involve valves/rocker’s arms while lower noises point to the oil pan or timing chain area. 

Record odd sounds happening for your mechanic. They can differentiate serious issues from minor ones that need attention sooner rather than later. 

Strange sounds could arise from simple fixes like loose belts or worn pulleys, but may also signal deeper problems if ignored. Don’t dismiss changes in your engine’s song – get pro guidance.

5. Low Oil Pressure

Oil is your engine’s lifeblood, keeping components lubricated and cooled. Low-pressure warnings mean oil isn’t circulating as it should. 

This subjects parts to excessive wear and heat build-up. Check your owner’s manual for normal oil pressure specs; readings even slightly under could indicate an underlying problem. 

Worn pumps/bearings or blocked pickups/filters commonly inhibit oil flow. Ignoring pressure drops risks seizing parts and costly repairs down the line. 

Have your mechanic inspect for leaks or blockages if you notice low readings – catching issues early prevents further engine damage. Relying on oil is crucial to your engine’s long-term health.

6. Overheating Engine

A hot running engine is a sign that coolant isn’t doing its job of keeping temperatures in a safe operating range. Overheating causes components to expand and contract at a rapid rate, increasing wear leading to engine overheating damage. 

Watch out for steam under the hood, boiling coolant, or temperature gauges hitting the red zone – all demand immediate attention. 

Common issues involve failed water pumps not circulating fluid, thermostat problems trapping heat, or cracks in the radiator failing to dissipate it. 

Don’t wait for overheating episodes to happen regularly – address any temperature rises right away to avoid warping heads or cracking blocks down the line. Your engine’s well-being depends on cool running.

7. Engine Power Loss

One of the most obvious signs of potential engine damage is a noticeable loss of power. Over miles increase, moving parts inside the engine will gradually wear down and lose efficiency. 

This can cause a lack of acceleration or the engine feeling like it has to work harder than usual to maintain speed. It’s best not to ignore this symptom, as continuing to drive without addressing the root cause can exacerbate the damage over time.

A sudden and significant power loss may require a more thorough inspection by a mechanic. They can do diagnostic testing to pinpoint if critical components like the fuel system, ignition coils, or transmission are at fault. 

Early intervention can often fix smaller issues more affordably versus waiting until major repairs are needed. So if you feel your vehicle isn’t as peppy on the road anymore, it’s wise to get under the hood for a professional evaluation.

8. Presence of Oil or Fluid Under the Car

Finding oil or fluid pooled underneath your vehicle is one of the most evident signs of engine damage. The engine contains precisely engineered seals and gaskets designed to keep fluids contained.

If you notice oil or fluid puddles, take your car to a car repair workshop to fix the issue. Professional diagnosis is mandatory for fluid leaks to identify the component needing replacement.

9. The Engine Keeps Running After Turning the Ignition Off

Another sign that one should not ignore is when the engine keeps running even after turning the ignition off. In modern vehicles, the computer is programmed to shut down the engine automatically once ignition is off.

If it fails to do so, it usually indicates a problem with the ignition, starter, or computer itself. It also poses a safety risk if the engine keeps running while exiting, as it could potentially roll away uncontrolled.

A simple ignition switch replacement may fix it, but the underlying cause needs determination to avoid repeated no-start situations.

Protect Your Car From Engine Damage

In conclusion, staying aware of common warning signs can enable early detection of potential engine problems before they require costly repairs.

FAQ's

Engine overheating damage is caused by low coolant levels or coolant leaks, failed water pumps, clogged radiators, etc.

Friction causes worn parts like pistons, rings, valves, and bearings to deteriorate over time if not properly maintained, making them the most common cause of engine failure.

If your engine fails, the first thing to do is attempt to safely pull over your vehicle to the side of the road as quickly as possible. Once stopped, you should turn the engine off, engage the parking brake, and call for roadside assistance.

If an engine fails while driving, you will immediately lose power and the ability to accelerate. This can be dangerous as you no longer have control over the speed of the vehicle. It’s important to manage momentum and steer to the shoulder to stop safely away from traffic.

When a car engine stalls, it suddenly loses power, also causing a loss of power steering and brakes. As long as you are not in traffic, you can put the gear into neutral and restart it.

A damaged engine can sometimes be fixed through repairs like replacing worn parts, etc. However, extensive damage may make the repairs too costly compared to the value of the vehicle.

Some signs that an engine may be damaged include strange noises, a loss of power, oil or fluid leaks, excessive smoke from the exhaust, or dashboard warning lights. A mechanic can properly diagnose the problem and determine if repairs can be done.
