More injector pump sealing. I pulled the rear plate and made a new paper gasket for it. Then I pulled out the idle regulator and found that its O-ring looked good, especially since I didn't have another one! (The HF O-ring kit doesn't go that big.) I don't think it would be too hard to replace on the car if I had to. I did dump all the oil out of it, I don't think it's supposed to fill up like it was. (Sitting it on its back will do that.) Finally I tipped the IP up on its nose and removed the bottom plate that covers the cam. It has a weird tapered wedge ring type of seal, and it was starting to look a little tired. I believe Casey said that on the 603 motors the big oil filter O-ring is a decent substitute. OK, but the 602, with one less cylinder, requires a smaller seal. I took one of the big O-rings and cut out about an inch with a razor blade, using a bias cut. I then glued the ends together with cyanoacrylate glue. (I have heard about this technique before, but this is the first time I have used it so far as I can remember.) The 'new and improved' O-ring fit into place over the 'bump' on the cover, I put the glue joint next to a mounting screw so that it would get a good tight pinch. I eased the cover into place and tightened down the screws. The cover tightened down all the way, the O-ring should have gotten well wedged into its tapered seat. We shall see if this works! I saved the old seal just in case, though if this leaks I think I should just try to buy a new seal. I finished up just as I ran out of time. It's just about time to start putting this pig back together!
