Can You Drive a Car with A Blown Engine?

It is said to be blown when a car’s engine can no longer be started. The engines are typically damaged by a cracked block or a deformed cylinder head. However, most drivers frequently ponder whether or not a car with a blown engine will start.

Although it’s not advisable, you can drive a car with a blown engine. Driving with a blown engine has significant dangers, including damaging your automobile permanently and putting other road users and yourself in danger.

You should take every precaution to avoid having an engine blow. Your car will run erratically if it blows, and you’ll have a big mess to clean up. Continue reading to learn what happens if you drive with a blown engine and how to determine if your engine is in excellent condition.

A Blown Engine May Not Start

Even while a blown engine can start, it won’t drive smoothly. It might not even survive the journey. This is because a blown engine results in at least one piston no longer moving up and down as it should.

A blown engine doesn’t appear to be capable of starting, but there’s a chance it could still function. If the engine starts to turn over again, you’ll be able to drive.

Beware of this outcome since the car will drive erratically. You’re better off pushing your automobile to a safer location if it struggles to drive or idles roughly since there may be hidden damage inside the engine that needs to be fixed. Your car may be able to start, but it will probably break down again or develop additional engine issues in the future.

If you suspect your engine may be blown, you should take your automobile to repair. They will identify the issue and provide you with a pricing estimate for fixing it. Check your automobile out if you hear odd noises or if it’s not operating properly. In the long run, it can end up saving you a ton of money.

Risks of Driving While Your Engine Is Blown

There are various dangers when driving with a blown engine, including:

  • A loss of vehicle control
  • Destruction of other components
  • Stalling
  • Increased risk of accidents

Control Abandonment of The Vehicle

When your engine blows, you won’t have much control over your vehicle. An engine that has blown won’t produce enough power and torque to carry your car steadily along the road.

You can still attempt to drive, but it will need more effort than usual because you will be battling the automobile at every turn.

Other Components Are Hurt

Damage to other parts of your car is one of the many dangers of driving with a blown engine.

All your car’s systems are under stress when you drive with a blown engine because they must make up for what is happening inside the engine block. Other components, such as the crankshaft, oil pump, suspension system, and more, may experience issues as a result.

The Vehicle Will Brake

If your car’s engine blows, it will stall. It won’t happen all at once; rather, over time, your automobile will have harder trouble starting.

If it occurs, you should get the engine checked out right away before something more serious occurs.

A Growing Risk of Accidents

It’s considered reckless to operate a vehicle with a blown engine. This does not imply that traveling great distances with a blown engine will result in an accident.

However, it does imply that you’re more likely to be involved in a collision than if your engine were in full working order. Avoid taking the chance of traveling a long distance with a blown engine!

Signs of A Blown Engine

You can tell whether the engine in your automobile is no longer working thanks to a few signs. It can be detrimental to your finances if you ignore a few of these red flags.

Check for the following symptoms to see whether you have a blown engine:

  • Strange sounds when starting your engine
  • When you brake or accelerate, the engine produces a weird noise.
  • Engine performance issues
  • Fuel efficiency decline
  • A lot of tailpipe emissions

Do not wait until it is too late to have your car looked out for if you detect any of these symptoms.

How To Keep Your Car Engine Well

Fortunately, there are also a number of indicators that the engine in your automobile is functioning well; you simply need to know what to look for and how to interpret the data.

To make sure the engine in your car is still running efficiently, follow these steps:

  • Look for leaks and damage underneath the hood.
  • Ensure that all fluids are at the appropriate levels.
  • Conduct an emissions test on your vehicle
  • Keep an ear out for odd engine noises

Search for Damage and Leaks Under the Hood

Always check under the hood of your car before taking it for a spin. Fluids might be concealed beneath the engine even though none are visible.

Before starting your automobile, you must top off any low fluid levels; if they are full, there are no leaks.

Be sure to check them out immediately if you notice any fluid leaks or damage to crucial parts like your head gasket or radiator.

See to It that All Fluids Are at Recommended Levels

Your engine’s performance can be determined by checking the oil and antifreeze levels, which should be at the prescribed levels.

It should be noted that low oil levels could indicate an engine block leak. Low antifreeze levels also indicate that the cooling system in your car isn’t working properly.

Do Vehicle Emissions Test

You may find out how much pollution your automobile produces when you have an emissions test done. If the pollution levels are excessive, there may be an engine issue that needs to be rectified.

You must drive your vehicle to a nearby testing facility to perform an emissions test. You need to be able to find out if there’s a problem with the engine with the aid of your mechanic.

Aim to Hear Crazy Engine Noises

Your engine may make an odd noise if something is wrong with it. You might be able to figure out what to do next by listening to these sounds, or they might be an urgent warning that your car’s engine is broken and needs repair.

Typical engine noises to listen for include the following:

  • Rattling or vibrating sounds
  • Squeaks, rattles, banging or chugging happens sometimes
  • Noise variations when braking or accelerating


Will a blown engine start, then? Yes, it is the answer. Driving it in such a condition is not advised, though. You might cause an accident or other issues for yourself and other drivers. The best action when there is an issue with your engine is to have it looked at immediately. The implications of driving with a blown engine are expensive.
