I have recently bought a beautiful example of a V8 730i 1993 model with everything working just as it should, that is except for the waterpump where the bearings have gone and the fan is all wobbly and it loses water out the spindle. I am quite capable of doing this so set about it today armed with a new pump to fit. despite a few awkwardly located 10mm bolts (and god knows how I am going to get them back in) I succeded in getting the offending pump off; this is where I hope something bad has not happened.
When I was pulling the pump forward to remove it from two metal pipes that appreared to come out of the space under the air intake stuff, the larger of the two pipes detached itself from the other end. from what I can gather it seems to friction fit itself into a hole with a rubber seal. I think I have relocated it and it seems quite well seated and isn't wobbly but how can I tell???? I cannot see it because of all the intake stuff. has anyone experience of this? and can give me some good news
