All Jeep "mark their territory" as a post on another forum stated - if they aren't leaking, they are out of oil! The distributor on my 'a1 is also out 180 deg - has been since I put the engine back in. It doesn't affect it any, and unless someone knows what they are looking for (as far as spark plug wires and firing order), the only that will know it is you! So, unless you have something major wrong with her, take her out to the rally and have some fun with her! I'm sure you'll find other things wrong while you're there. If she acts up, there will be plenty of others to ride with, I'm sure.
I'm just saying this because mine is about the same. I've got funny noises, a gas gauge that works when it wants to (I know it's a ground problem - just thought I had it fixed), headlights that burn out too quick (hope I have that fixed now - with extra grounds), LEAKS (I will fix the fuel leak before I go though!).
Anyway, take her out and enjoy her - park her only if you have to.
