Hay Dr. Kilmer, how are you? I have a 2002 Honda civic ex, automatic with 3 problems 1st when starting my car, oil leak and I couldn't find the area. 2nd : when car starts antifreeze should travel, l leave the cap open and start the car, antifreeze should travel, however doesn't seem like moving. The damn thing I ordered a year ago, and I feel stupid because I didn't pay attention.
Welcome to the forum. You should open a separate topic for each issue. Please and thanks.
For #1 you said you can’t see where the oil is leaking from visually - in that case try the below. It’s worked for me every time on my cars.

For #2 I am not following. How do you know it’s not circulating?
and then what is the 3rd issue?
No, coolant should not be flowing through the radiator when you start your car. Only after it reaches operating temperature.
