keep looting/dismantling cars, and "working Stiffs crates" and you will get engines and batteries eventually.
you will have to break down the cars that have body panels (not car frames) with a wrench to have a chance at getting engines.

Take cars apart with a wrench or you can find them in Working stiff crates sometimes. Red cars seem to be better for giving engines. Loot the car first. Sometimes you will get an engine from there. Then take the car apart with a wrench. Make sure you have at least 10 empty slots in your backpack. Engines and batteries dont stack. All the other thngs you can get from cars do. Good luck.
