If you mount the oil door on the cowling the way the plans show you, your door will work just fine. However, over time, you'll notice a black streak on your cowl from the hinge line streaking aft. I'm not sure of why the streak forms, but it does. So on my Rocket, I fabricated a hidden hinge on the door.
I bent some aluminum to make a hinge as shown. I also reinforced the hinge mounting area with about 10 plys of fiberglass. The idea is to allow the door to swing up and away and not hit the cowl until the hinge is stopped by the lip in the opening.
When you're done, it looks like this.
