The phrase “blown engine” can refer to several things that can happen to a vehicle. If you’re a car owner, hearing this phrase should send a few shivers down your spine, knowing that you’re in for a hefty repair bill.

6 Signs of a Blown Engine Every Car Owner Should Know

The engine being blown in a car is a pretty loose term. But the most common use of the term is to encompass any major damage to internal engine components or if the engine is worn out significantly.

Wondering how to tell if the car engine is blown? Here are 6 blown engine symptoms to look out for.

1. White smoke is coming from the exhaust

If you see white smoke coming from the exhaust, it usually means you have coolant in your engine, which is a pretty serious problem. Unlike typical exhaust smoke, the consumption of coolants will produce an awful chemical smell.

2. Blue smoke coming from the exhaust

Blue smoke may billow from your tailpipe, indicating that the combustion chamber is flooded with engine oil. If it’s consistently happening, it’s usually a sign that you’re going to need an engine rebuild or replacement.

3. If you hear loud knocking sounds 

Sometimes, your car will have a knocking sound that will eventually go away. If this is not the case, then your engine is probably suffering from wear and tear. A blown engine sound has knocking metallic clanks, which means it’s probably on its last legs.

4. Your car’s engine won’t start

Your engine not starting can be due to many factors. It might mean that you need a new battery, a new alternator, or a new starter. If your engine is spewing fumes or has knocking sounds before ultimately dying out, then you definitely have a blown engine.

5. The caps and the hoses keep coming off 

The engine caps and fluid hoses pop off because of too much engine pressure. The pressure builds up because of the fuel combustion. If left unrepaired, you might suffer massive oil or coolant leaks. 

6. Your car engine lacks power

It’s normal for cars to lose power over time. But if your car has a 200 horsepower engine, you feel like your car is dragging along with just about half of its power, then you have a blown engine.

These are the usual 6 signs of a blown motor. If your car is showing any of the blown motor symptoms, consider selling it. 

What Causes an Engine to Blow

In the lifetime of a vehicle, major engine failure rarely happens, but you can spot the signs an engine is blown. What causes an engine to blow? Here are the 4 most common reasons why you will have a blown motor.

1. Submerged or Hydrolocked Engine

The engine is not built for compressing water. If water finds its way into the cylinders, the piston and piston rods will break or bend when it attempts to compress water-mixed fuel.

2. Timing belt failure

When the engine is running, ticking sounds from beneath the hood can indicate that the timing belt will fail. If your car’s timing belt fails, the pistons may collide with the open valves. Sounds like metal clanking loudly is one of many blown piston symptoms

3. Low levels of engine oil

If you don’t have enough oil in your engine, it will eventually break down. When the oil pressure warning is lighted, you should turn off the engine as soon as it is safe to do so. 

4. Overheating

When the temperature gauge begins to rise, pull over and come to a complete stop. Allow the car engine to cool down and check for a coolant leak. If you’re having issues with overheating, then it’s one of the most obvious blown engine symptoms
