Hey John. Welcome to the forum
Me and smoke generators just don't seem to get along. My first one lasted about 10 minutes!
not even long enough to shoot a video.

Noticed the horizontal reciprocating piston. Oil cooks in front of it , piston pushes out. To create what you want to do seems very elaborate and hard to do, especially at 1/14th scale?
Oh wait, I have to take that back. Nothing is impossible to build! People prove it all the time! Almost a daily occurrence on this forum
Adding motor oil won't work. It's too thick and there's not enough heat generated to get it to smoke.
I couldn't find any " smoke oil " here at home but was told that mineral oil works fine and I got that at the local pharmacy.
I have a Rc tank that has a smoker and even that one quit on me in no time.
If you can figure out how to change the color from white to black, you may become a very wealthy man.
Keep us posted
