Engine has done a couple thousand kms so far, and no leaks whatsoever.

Thanks for replying to that question. It will come in handy as I progress to that point. Right now I'm just starting the reseal.

And the reseal starts. First up I inserted the new stud with a coating of Loctite 263. I did the same to one of the studs holding the oil pump in. As soon as the Loctite cures I can take the nuts off them.

Next up was a lot of cleaning with IPA, then blowing clean air into the galleries.



I then renumbered the bearing areas based on photos I took at the time of disassembly. These match the bearing shell numbers so everything goes back exactly where it came from. I cleaned each bearing shell with White Spirits.

Oil pump, intermediate shaft and chains installed.

Nose bearing seal inserted. Alcohol wipe, then bead of Curi T and pushed the Elring seal home by hand.

Crankshaft seal part-installed, assembly grease on bearings and place the crankshaft in. I didn't put it fully in as I need to do the nose bearing sealant at the same time as I start to seal the case. That will be this weekend.
