Distributor removal/intake manifold

[Kneale Brownson]

I'm trying to get the stupid glued-on rotor off the distributor on my 
200q20v avant.  Tried crushing with water pump pliers, but could not 
budge it, so I'm assuming I have to remove the distributor to get access 
to the rotor.

Do I have to remove the intake manifold to get the distributor out?  
Looks like I have the stupid security cover on the bolt to the 
distributor still in place. 

I don't have a gasket for the intake manifold.  Would I need to replace 
that if I remove the manifold?

Is it necessary to glue the new rotor back on if I ever get this 
solved?  I'd think the distributor cap would prevent any riding up of 
the rotor on the shaft.

Some A-hole replaced the rotor with the wrong one and solved the 
over-extended contact issue by folding up both ends instead of by trimming.
