What not to do when installing delivery valve seals. After reading most of the information regarding changing out the seals, I proceeded to take on the job. Removed the IM, hard lines, lock down collars, and, instead of entirely removing each valve holder, I partially unscrewed each one, and worked the old seals out. I read of this technique in one of the posts, and felt that it would eliminate loosing any of the small parts. The old seals did not follow the holders out, but I was able to gently work them out with a small screwdriver. When I went to install the new seals, I failed to notice that there were two grooves cut into the valve holder, and I inadvertently installed the new seals on the upper most grove, torqued the holders down, reinstalled everything and went out for a short spin. Well, after about 3 minutes, I went out to take a look, and almost all the delivery valves were leaking. Back into the garage, and with nothing else to try, I decided to carefully remove one of the valve holders and have a look see. Well, it was then that I realized that there were two grooves in the valve holder and I had installed the new seals in the uppermost one, which is the wrong one. All work was repeated, with the new seals going into the correct grove, and I am happy to say that everything is dry as a bone. Just like to thank everyone that responded to my questions, especially Terry.
