How to tell if the engine is locked?
Understanding the main symptoms of a locked engine, every driver must avoid dealing with complicated repair costs and safety situations. The following list provides you with the most common signs indicating that your engine is locked or is about to get completely locked:
1- starter motor does not respond
The first and most common symptom indicating a locked engine is when your starter motor does not engage. You might try to turn the key in the ignition switch but realize that although the certain motor is doing is making some clicking noises. In that case, it could be a problem related to the engine lock.
KRemember that the ticking noise from the starter motors does not always indicate a locked engine. In that case, you need to work with your mechanic to identify the potential culprit because it could be a problem related to the battery or the starter motor itself.
2- crankshaft does not rotate
You might also notice when your engine is locked that, the crankshaft does not rotate. You can simply just for that manually or, using a range, try rotating the crankshaft, and if you feel that it's not responding, it means that something stuck in the engine is leading to what's known As a locked engine.
Note that this type of test requires certain mechanical skill sets; if you don't feel comfortable doing that, it's highly recommended that you keep it to professionals to avoid dealing with problems that you could cause when trying to force the crankshaft to rotate, which could lead to breaking it.
3- car making weird noises when starting
Another common symptom of a locked engine is when you hear some weird noises coming from the vehicle. These noises are typically grinding or banging. And sometimes, it can be allowed metal on metal scraping, which indicates that your engine is grinding against each other and might lead to damaging the internal components.
As a rule of thumb, automotive experts typically recommend that you never ignore any noises from your vehicle. These noises could be just a sign to pay attention to what's happening in the car. The more you wait on these noises and the louder they get, the higher the chances that many internal components fail.
4- significant reduction in In-vehicle power
when the engine is locked completely, your vehicle might not start. However, in some early signs, you might notice that the vehicle is not producing the general energy you're used to. Therefore, you mustn't take this problem lightly because it could indicate your engine is dealing with an initial lock.
This is another common symptom indicating some other problems. Therefore, you cannot immediately assume that your vehicle is dealing with engine locks because you're dealing with a power reduction. The mechanic should be the best person to help you pinpoint the root culprit for this problem.
5- your car does not start
As we mentioned earlier, the easiest sign indicating that your vehicle might be dealing with a major engine lock is when the vehicle does not do anything. In other words, if a car does not start at all and the engine does not crank completely, your engine is seized and needs immediate attention from your mechanic.
Remember that this is another common symptom indicating a problem with the battery for example. Therefore, you might want toto check on the battery first and determine whether it's in good shapt because it might be a simple problelikeas tightening the battery terminals to get the vehicle working.
6- the piston is visible
Suppose you did not catch any of the mentioned symptoms, and your engine lock got more severe. In that case, you can easily see that the Pistons are sticking out of the engine, indicating that they were completely locked and some of the internal components were loose to show in the wrong place. Hopefully, you didn't need to get to this point, but it is one of the clear signs indicating the complete engine lock.

· engine overheating
engine overheating is another problem that could lead to engine lock. If you don't have the proper lubrication and the internal components are grinding against each other, it could be vice versa.in other words, engine lock can also result in engine overheating in some instances.
· mechanical damages
When the engine has some major failures internally, it can also get locked. In other words, if any of the internal components is damaged and is not operating as it should, it can cause some troubles to the engine cycle and performance, and therefore, you can deal with a locked engine.
· foreign objects
Finally, if a foreign object gets broken and makes its way to the engine, it can lead to a complete engine lock.

If there's anything in the way, it can prevent the other components from operating as they show.

Remember that the costs of fixing a locked engine depend heavily on your vehicle type and the location where you get the job done. That's why you'll see that the quote you're getting from a dealership will be much higher than someone else's getting a quote from a small independent shop.
