Removing the distributor for intake manifold gasket replacement, any ideas? The distributor gets stuck before second O ring is exposed. Turns easily at this place and on pushing back into position it turns correctly. In the workshop book it shows that there is nothing but maybe the locating pin has been displaced and is partly out but I doubt that as you can't feel the obvious movement of this pin rubbing against Aluminium. I could keep on going but why?
