So I went down to my HD dealership and bought a genuine O ring. I tried to fit the cap but I still couldn't get it to turn those last 20 degrees . What I then did was make a little sanding block and used it to slightly round off the angle on the spiral groove just where it transitions to the lock position. Result , turns all the way and doesn't leak !
