Lets talk leakless water pumps!

[Jason in TX]

28 Special Coupe - I 've used the bushing that is in the pump you're using on a couple rebuilt pumps I've built up a few years ago and they still aren't leaking, so maybe I'm over thinking it. It's just that I've messed with swapping water pumps on the side of the road, in a field, in a hotel parking lot and in my garage and the amount of annoyance it takes to swap one out, I just want to get the best bang for the buck!

PS - If the grease is easily coming past the front seal out toward the packing nut after you remove the packing nut, don't you think there is possibility that the same amount of grease is also going out the back seal that has no packing nut there either, only coolant? My other thinking is that there is no place for that grease to go, so shouldn't it not require much more greasing beyond when it's assembled, and beyond that, maybe a tiny little squirt maybe once a year, or couple of years depending on the amount of driving?
