Took the whole system out. What a pain to get to it. Had to remove throttle body, intake hoses, unbolt both manifolds, loosen alternator, loosen ac comp, and still some bolts are so hard to get to even using a universal joint ratchet. Need a lot of patience and I stopped trying to remove the manifold half way when I saw what all I had to remove to get it out. Anyway, its full of carbon and instead of trying to salvage I decided to replace the major ones so I never have to do this again until I die.
Replacing:
Porsche Boxster Air Injection Parts
Vacuum tank
Change over valves (i have 2)
Check valve
Shut off valve (most expensive item)
Y pieces
Gaskets
Rubber hose elbows
Also replacing the entire oil fill tube line. With all these replaced my car should never give me the codes for SAS. If it did I'm going to open the intake and throw a stick of dynamite and start the car.
