I have no actual concrete reason why but something triggered me to go looking for videos of hydrolocked engines on YouTube. You know the ones. These are the people who decided that their (insert your car name here) was capable of fording a veritable river and then ingested enough water to lock the engine up tight when it wasn’t. Obviously this scenario can end one of two ways. Since water cannot be compressed, engine components like rods, cranks, and anything else in the way bend and break. If you get lucky and shut it off quickly, you can save the engine by doing what these guys did, which is to pull the spark plugs out and turn the engine over so it literally pumps itself out.
The engine we see here is a V8 in a BMW 650 sedan that was plowed into a couple feet of water. Those intake tubes became water scoops and filled this sucker to the brim. The 4.4L V8 makes nearly 450hp and as you will see here, it has some serious compression because it shoots the water out with ferocity! This isn’t watching an old Jeep inliner blurb some water out of the spark plug holes. This sucker shoots the stuff like it means it.
We may need to make this into a contest to see which engine has the most violent pumping action. If you find something better than this we’d be shocked!
