The intake manifold is a bear to remove. If its not leaking I wouldn't replace it unless you took it off for something.

If you're doing valve cover gaskets new plugs are a good idea, and Vanos seals will only take another hour or two since the cover is off anyway.


Vanos wouldn't be related to your starting problems, it could be fuel related, it could be the starter.
