When I am not stranded, I will do more searching than the couple searches I have done.  For right now, I am a new owner with a new-to-me 2002 S with 116k.  I had put a 1/2 quart of oil in when I brought it home, so I have been able to add oil normally.  Since then the only things new that I can think of are that I have put the roof in service position twice and when I was first filling tonight the car was still jacked up on the drivers side from when i drained it.  Here is what happened:
Tonight after I drained all of the oil out, I closed it up and started to fill it with oil.  It seems to go straight down to the ground.  I went down to watch while my son poured some and it came straight down the passenger side.  It was not leaking from the drain hole nor the filter canister.
  I looked down the fill hole and the tube curves toward the front.  I can't see what is wrong nor understand why it became a problem.  
Please help.
