Guys- the whole reason I bother documenting this stuff is so other people can reproduce the procedures!

Anyway, I wanted to show a few more photos of the sealant injection process. After I failed the first time, I wasted the $60 cartridge of adhesive and had to buy another one from the dealership. But before I was ready for attempt #2, I emptied the first cartridge and filled it with honey because it has a similar viscosity. I then dialed in my technique using honey. Once it was proven, I disassembled the engine and cleaned the honey out.

To make sure I had enough adhesive to fill both sides, I measured the displacement of the piston before & after each injection. Interestingly, each injection used exactly 25% of the cartridge volume. So if you undertake this procedure yourself, know that without wasting material you can safely have one failed attempt.

Anyway, here are photos from the actual injection. The previous photos were honey injection.
