If the nose of the impeller is not touching the back of whatever, then it's definitely NOT the 1st or 2nd generation. My guess then would be the 3G, but whatever it is is better than the original(1G) seal, so you should not have to worry about an "explosion".

Arrrgh! Another delay on the Healey engine. =:-( Got a call from the machinist - He found a crack in my head after skimming it. <mumble> It is a relatively benign crack, from a water jacket opening. Apparently small, but of course I do not want to permit it to spread. I could take a chance and install the head as is, but I would be waiting for my motor to puke coolant into the combustion chamber. I told him to Heliarc it and then reskim it. He said it would add to the lead time on my motor. Well, the sun is only expected to burn for another three billion years, I guess I can reassemble my motor IN THE DARK.

Lads - A minor update on Rusty... I have learned that the engine torque damper can cause cracks in the firewall if it seizes. Thankfully mine has not seized, but the bushes are shot having cracked and a few bits have fallen out. It is important that the damper be functional or you will end up needing to weld your firewall. I have seen some photos of such cracks on the Jensen Owner's Club site. After some research and a few dead ends, you have some options if yours has seized:

Lads: The impossible has happened. No, I didn't get a date with Heidi Klum. =:-( I got my engine back from the machine shop before Christ returned. Yes, it's true. Saints be praised. I started assembling my pistons (Carrillo BTW, nice stuff) and happened to spend a minute staring at my head as I contemplated the parts I have yet to acquire. I noticed something interesting. The machinist had found a crack in the cooling jacket after skimming the head. He sent it out to be heliarc welded, and finished the work. I have pointed out the repair in the picture. Notice anything? The combustion chambers nearest the crack are pitted, the chamber furthest away is pristine with no pits. Apparently the car was driven for a while with coolant leaking into the chambers. The combustion process turns the water into superheated steam which is very corrosive to aluminum - hence the pitting. You also get white smoke coming out the tailpipe which is a dead giveaway you have lost the head gasket. Apparently this was ignored and the car was used until it would no longer run. I also have reason to believe that the motor lost a cam belt at some point, as four of the valves were bent - but still doing their job well enough to continue to drive the car. My suspicion is that the valves bent the most were replaced, and the valves that merely "kissed" their respective piston were ignored. <sigh> I will give another update when I make some real progress assembling the engine.
