It is not necessary to remove the manifold, but he has the benefit of a proper lift. I remember you said changing yours caused you some grief. He also billed me an hour for the labor so I doubt he had to take out the manifold.

Yes, as I said above, replacing the purge valve took care of the problem. I have an extra valve if you need it.
