How to fix a blown engine

An engine does not have to literally blow up. Smoke and steam can suggest a blown engine and in rare cases, fire. Here is how you can fix a blown engine

There are many issues that might cause an engine to be considered blown. A cracked block, busted exhaust valves and destroyed pistons are all severe engine damage. Sometimes a valve breaks and punches through the top of a piston.

The broken valve will become incredibly hot and caused pressurized oil and smoke to shoot out of the top of the engine. Many times this requires a complete engine replacement.

Should you fix a blown engine?

The answer to this question depends on a couple of factors. For instance the extent of damage should guide you on whether to repair the engine or just buy a new car. The engine can be quite a costly affair to repair and if the amount is almost as much as the value of a new car, you would rather buy a new car.

For old vehicles, a car owner should consider buying a new car because the cost fixing an old blown engine will surpass the cost of the whole car. It would be wiser to let go of the old thing before it puts a dent in your bank account.

Steps to diagnose a blown engine

A blown engine can be an effect of anything whether mild or critical. This is why it is important to first know what the problem is before deciding on what to do next.

Teardown the engine carefully. Troubleshoot the engine by tearing it down part by part in an organized manner. Check for fragmentsand any broken things floating around in the oil. Inspect the pistons and chamber for oil leaks, water leaks or any melted parts.

Look for fissures in the heads. This should be an initial check, and even if you do not find anything wrong, take the car to a qualified mechanic to examine for any cracks that can’t be seen by the naked eye. This especially applies to engines blown from overheating.

Steps to diagnose a blown engine

Eject the rods, pistons and crankshafts and check for signs of gouging.

Using these steps, you will be able to fix a blown engine or determine whether or not it’s a good idea to fix it.

Conclusion

Proper maintenance goes a long way to avoid a blown engine. Regular oil changes are encouraged while bad habits such as revving too much and driving at high speeds for long period should be avoided. It’s also important to consult a mechanic immediately you notice early symptoms of engine damage and fix it before it becomes something serious and expensive. Such trivial things will go a long way in ensuring your car lives a long happy life.
