I decided that putting the case sealant on to the left half (not the half mounted to the stand) made more sense, as it's way easier to apply; you don't have to negotiate around all of the studs. Lots of threads on this topic- no obvious downside that I could find.

Also, lots of debate out there about whether or not to put sealant onto the bearing saddles. Factory didn't do it, so that's a strong argument. Also, there's a risk that sealant on the bearing saddles could force the bearing journals out of round, which would be bad... On the other side of the argument is that high performance engines often shuffle-pin the saddles to prevent "chatter", suggesting that adding some shear strength here would be a good thing. Anyway, not saying it's right or wrong, but I decided that a super-thin coat of Loctite 574 on the saddles was a good idea. Personally, I can't see how that would deform my bearing journals into ovals, and if I get some shear strength out of it, then great.

So, the 574 goes on first, as it's anaerobic and I don't have to worry about the set up time. Here I'm applying it; keeping it super thin, and wiping away any excess.





Next, I put another skim coat of 1211 on the #8 bearing journal.

Then, on to the perimeter, where I used Threebond 1184. I squeezed out a medium sized bead all the way around. Here you can see the 1184 bead in light grey, the 1211 in white, and the 574 in orange (and assembly lube in dark grey).




At this point the clock is ticking, so I quickly smoothed out the 1184 with my finger. Turns out I had more than enough sealant; as I smoothed it out I ended up removing a fair bit of it. Here it's looking pretty good:




There were a few spots where I had a lot of spillover, so some quick work with alcohol wipes was required.







Nice! Let's slap it together!
