How do you damage a cars engine?

1. First find a large jackhammer or pickax and tear away as aggressively as possible. Spare no parts !

2. Now pour a few boxes of black powder under the hood.

3. Finally, light a match or two. Throw one into the gas tank and one in the engine.

I guarantee results!;)

Drain out the antifreeze and engine oil and run it till it quits.
