If you are planning to demolish your car’s engine, there are a few things you should expect, some of which include lots of smelly smoke, sparks, vibrations and even some flames if you leave it long enough. If you are doing this on purpose for some reason and you have an audience, ask people to make guesses at how long the engine will be able to run for. You will start the car and let it run without adding oil to the crankcase. Yes, I know it sounds crazy, but if that is what you want to do, this is what must be done! Depending on the engine of the car, it might run for only a few seconds or it can last for minutes. It all depends.
What needs to be done in order to destroy all car parts as well as any car accessories that may be in the car is to firstly warm up the engine while making sure that it is functioning correctly. Once you have it running fully, drain all of the engine coolant as well as all the engine oil from the car. You can even do this as an event and use wrecked vehicles from impounds. As long as you are not harming anyone or anything and you use an area that will not catch alight and all goes well, then there should be no problem. Once you have drained the oil from the engine, close the hood of the car, start the engine, and put a brick on the accelerator. Have a stopwatch handy. Make sure no one is near the vehicle, and have a fire engine standing by.
Nothing will be unusual at first, but after some time the engine will start to rev really high. Then it should start to slow down, and if you haven’t seen this before you will probably think that it is going to be a dud and nothing more is going to happen. But the engine will start to run slower and slower because the bearings are beginning to seize on the crankshafts and the pistons are starting to get stuck inside the cylinders. The engine will slow down to almost nothing at all, and then all of a sudden you should hear a loud BANG!
It might take longer than you expected or it might happen sooner than you expected; you never know. It might not even happen at all! Just be prepared for anything and have people on standby should something go wrong. After the loud bang there should be a few more bangs as car parts and car accessories are being destroyed, connecting rods are being snapped, and holes are being punched into the sides of the engine. If you didn’t drain the coolant when you drained the oil you will have a big mess to clean up, and you surely do not want that. If you are lucky the engine will continue to run on the few cylinders that might be left. It might run with jerks and sobs or it might run smoothly; it all depends. The result isn’t always the same.
Smoke should be seeping from the engine and the gaps in the fenders right about now. Even though it seems like the engine should die, it is likely to keep running. If you have gotten this far in the engine demolition attempt you are probably going for close on five minutes now at this stage. The engine should be making more loud noises soon and the revving just about to surge. This should be the last stage of the event. Once the engine finally gives its last breath of hope before it dies, don’t be surprised to see flames erupt from the engine. At this point you need to get the fire engine involved and have the firemen extinguish the fire before the entire car explodes. Do not let anyone lift the hood when the flames have begun as that will make the fire worse.
So this is what happens in the event of engine demolition. Prepare to watch car parts and car accessories never be the same again! Although it is fun to watch and to guess how long the engine will last before it dies, do not do this without permission and experience as it could become dangerous. Make sure you know what you are doing before you attempt anything.
