I got tired of replacing them too, when I rebuilt my last engine I did a cheap-a$$ fix. Take a couple of tubes of Red RTV and stick the nozzles into the vent holes in the rubber that surrounds the bearing, one side at a time at angle of rotation, and fill until it won't take any more. leave it set for about a week ( I rebuilt an engine ) and install. I did this 5 years ago as an experiment and it still works. I do like the idea of the poly support and will look into it as an option, thanks for the info. Your experience may vary.
