  1. I was working from memory and it turns out I am dead wrong.  It is confusing with the changeover designs.

    From 1997 to 1999, Porsche use a dual row intermediate shaft bearing which has proven to be as robust as the larger single row used from 2006 through 2008 model years. The IMS Class Action Lawsuit filed against Porsche revealed the factory Dual Row was much stronger than the Single Row used from 2000-2005.

     A 2003 would have the smaller single row bearing.  Just get it replaced with the Solution and you are done.

  2. In total desperation, you may have to pry the alternator out.  Rotate it as far as possible clockwise, remove the long bolt and pulley, and try to jam a thick screwdriver or small pry bar underneath the alternator rear mount arm.  You might have to be creative with a block or piece of wood to get the leverage right.  Be very careful of the oil filler tube.  It can crack easily.

  3. Are you sure you have not already moved it enough for the alternator right side to come up? Pull right side bolt all the way out and see if you can lift the right side up and out.  It might be a little bit of a struggle but if it moves up you can get it out.  I remember I had to go back and forth a few times, bolt in and whack, bolt out and try to lift, bolt back in and whack even harder, bolt out and test lift again.

  4. The bushing only needs to move enough that you can rotate the alternator up and out.  It does not have to be pushed all the way into the rear mount arm.  It really only has to move enough that you  can lift up the right side of the alternator easily.  Once you have the alternator out you will see how it all works.  With the left bolt out, how easily can you rotate the alternator up?  Or can you not rotate it at all?

  5. I would say you are going to have to keep at it.  Do exactly what the instructions say to do...back the long bolt out 3 turns and whack the bolt head hard.  Harder than you think.  The rear bushing has to move in order to create the space needed to remove the alternator.  I put a towel on the car to protect it and used a brass boat prop shaft.  Lined it up on the bolt head with the end of the prop shaft outside the engine bay and hit it with a sledge hammer.  Don't overdue it because you can break the rear mount.  It takes just the right amount.

  6. Replacing the AOS is a major pain in the butt job.  It will test your overall mechanical skills, tool set and patience.  For that matter, it is a job I never want to do again. It took me 3 days.  Lowering the engine is only the first step, so you need to read up on how to do  it.  You also might get a couple of quotes from experienced mechanics to compare with how much time you will have to put into it.  The AOS  can be purchased for less than $200.  Only get an original Porsche AOS.  This is one job not to go cheap.


    If it is not spraying coolant all over the engine bay, more like just weeping, you can wait.  Keep a very close eye on the coolant level.

  7. Get the CEL code again and post.  Before you proceed, either DIY or shop, we can help you narrow this down.  I certainly would want to know specifically and exactly that this is the problem before chasing ghosts and replacing parts.  Also, what year and model?  Other recent maintenance or problems?  There are other valves and components in the evap system to consider.  See here
