They do this all the time. The trick is to do it WEEKS before event takes place and stockpile them. You also need to make sure you have even distribution of engines. If you don't, they won't give you engines you are short on. Also, and what helped me, if you have a ot of engines compared to others (in my case v12) you will get a lot more of them. This strategy worked for me. I had 18 when I started.
