Well, after watching this video I am positive that you will take your car to the mechanic for every little thing, you won`t want to touch and ruin something. So what exactly happens here?
This guy here decides to remove the engine himself and, in order to show the world how it is done, he puts a camera. The footage instead turned out to be how not to remove your engine. He may have tried to put the engine gently down, but the reality was different, he dropped the engine on the ground. It is such a shame because everyone knows that in those types of situations the best thing to do is use the engine crane.
Check the video and pay good attention on how not to remove the engine yourself.
