I did a search on the workshop forum for a thread concerning removing (& replacing) the throttle shaft seals in the plenum. I didn't find one that specifically dealt with this issue. We are getting our plenum & manifolds ready to have them ceramic coated and as the seals are shot anyway, we need to replace them. It appears that you cannot drive them out from "the other side" as the ID of the metal seal housing isn't much smaller than the hole in the plenum (or the bushing anyway). Does anybody have any words of wisdom (or experience) on how to remove the seal bodies? We have new ones to go back in. I really do not want to damage anything and it looks like that would be fairly easy to do. I have received a couple of thoughts, such as prying them out, drilling them and "hooking" them, using a drift or pin punch, or a small seal puller. We are looking to add as many ideas as we can from an experienced pool to improve our chances of success. Your input will be appreciated.
