What Happens When a Timing Chain Breaks

Model: (Various brands) Various
Part: Timing belt

In this video, we will see the disasters that can occur when a timing chain breaks. If we are very lucky, the damage is limited to the broken chain, which may just get tangled at the bottom, allowing us to simply restore the timing without any mechanical compromise to the engine. With the installation of a new chain, everything will work perfectly again. Unfortunately, there is a second scenario where other mechanical parts suffer severe backlash, such as the valve rockers - as shown in the video - which appear to have literally exploded.
