So I started to disconnect everything attached to the intake manifold on my 1996 2.8 12v quattro in hopes of getting the manifold off so I could replace the plenum gasket. I have disconected everything including the throttle body and the 4 visible allen bolts that holds the bottum half of the manifold. So now the manifold still doesnt come off. I have left the injectors in. Now my question is is there anything else holding the manifold on from the bottom? Or do I have to take off the manifold off in two pieces? Thanks for your help.
