What causes an engine block to crack?

Answer

The most common reasons an engine block will crack are actually simple oversight. Low oil is the number one cause for a block cracking as the lubricant isn't there and the next thing you know parts are jamming up and the torque keeps coming busting the block. The other reason is driving with no coolant in the vehicle. Driving the vehicle while it is overheating will cause metal to stress and crack as well as adding water to a hot engine. Those are the reasons it happens.
