If you are trying to replace the entire line with the intake in....wont happen. Been there. The only way to do it is to cut the new line in half and then splice it together with a hose & clamps. Getting the intake manifolds off with the engine in....is possible but it is going to be a lot of work, more then you might think and chances are you will need new intake gaskets & 1 or more injector seals by the time you are done.

You will also end up braking some/if not all the original vacuum lines. It happens, they are old, very thin/crappy plastic so have some vacuum hose, connectors, T's, etc.
It's been a while, but I don't remember the intake manifolds being *that* difficult to remove. For installing the hose I think that I manged to lift the intake a few inches without pulling it all the way off the engine. If the vacuum lines have not been replaced, they ARE brittle and should be replaced now anyway. The intake manifold seals that I have seen so far - that green rubbery kind - hold up well and can be reused.

On the other hand... if you are not comfortable doing what STL described, consider having it towed to a Porsche shop. :dance:
