Video: Watch someone blow up a diesel engine, because he can

Catches it all on video, as well as the aftermath

2w ago

One of the first jobs I ever had was working on diesel engines. The big industrial ones, not those tiny things in cars.

There of course several advantages to having a diesel engine in a say a truck, or in my case, a boat. There are fewer moving parts, and diesel engines are much sturdier than gasoline powerplants. One of the disadvantages, however, is that if not properly taken care of a diesel engine can do something called “run away.” This is a phenomenon that sees the engine speed up and keep going until it blows up.

During my time as a mechanic, we were always taught this could happen, but I never saw it for myself.

Until now.

Youtuber KT3406E setup a 1970 something GMC truck with a Detroit-Diesel 8-cylinder engine under the hood and stuck the injector racks wide open. The engine lasted eight minutes before the engine failed in spectacular fashion. The Youtuber not only videoed the disaster, but he also produced a video of the teardown, which to an old mechanic such as me, was just as interesting.

  • I’ve seen those old Detroit’s run away before. Kinda scary the only way we stopped it was by taking a folded up tarp and putting over the air cleaner but even then it was sucking so hard it was sucking the tarp into the air cleaner and it was collapsing the rubber boots on the intake. Finally it bogged out and ran out of air. Two months later the engine popped.

  • That was NOT a 2 stroke engine. You can see the valves move when he first starts it with the valve cover off. 2 stroke engines don't have valves.

  • I watched binged watched this guys channel a week ago. Although it goes against my nature to destroy things, he is really good because he tears it apart to determine the reason for failure. This guy really appears to know diesel engines and he apparently is very skilled and knowledgeable on how to put them together. He destroyed a bus in another video and showed how a front end collision is horrendously dangerous for the drivers of those type of buses.
