Correct........"driving" those side seals in can move the retainer........because as you know, you can't fully tighten the retainer and THEN get those seals in, you have to do it all together. So after it "fits" right, fill the channels with RTV, just a bit on the bottom...NOT a lot and drop the retainer in, tighten it down, clean off excess. Usually at this point, I will take a tube of RTV and use the white tube that comes with them, with just a bit cut off the end to make a small bead. Then put a small bead down each side and across the bottom, to make SURE there is no opening in the RTV seal
