Assemble my "Rocket" (maybe...)
 

Time to assemble FC S5 Tll, Have noticed that people are using different components to seal the engines.
Water seals: 1.Use Hylomar, because it dries slowly and do not attack the rubber. 2. Do not use Hylomar it dries to fast; use silicone in the bottom of the grove in spots to keep the seal from moving, noting else.
Corner, side, oil and apex seals, 1. Use ATF in small amount. 2. Use regular motor oil in small amount. 3. Use Motor assembly grease (Petroleum grease) cover well.
Housings and E- shaft: Motor oil or Assembly grease??
I have not figure out how to pre-oil the engine, as we normally do with piston engines. Right now I plan to crank it with the starter and cut out the fuel until I have built up oil pressure. Any input on this would be appreciated. Thanks

I love Hyomar. I use the thin formula and put it in a syringe so I can quickly apply it to the coolant seal grooves and oil passage o-rings to hold them in as I assemble the motor.

I use vasoline for its stickyness to keep the corner seals, sideseals and oil control seals in when assembling the motor. Smear it into the seal groove/hole and then put the springs/seals in and add a little back over the top on the seals to hold it is while its upside down.

I use engine oil on the bearings/rubbing surfaces as per FSM while assembling.

I use silicone (Right Stuff Imports or Hondabond) for the housing "legs", front cover, oil pan, eccentric shaft nut, etc.

To prime the motor you can take off the oil filter and pour oil into the passages to fill the oil galleys, put filter back on and then turn the engine over with the starter motor and injectors/spark/fuel pump disabled.

Once you see pressure on the oil gauge enable the engine to run and start it and check for leaks as it warms up.

If you don't see oil pressure find out why before starting the motor.

for the water seals, the main job of whatever you use is to keep the seal in place during assembly. i've used a all of the things on your list over the years and they all work.

second, assembly lubes; again a little dab of something like vaseline helps to keep the seals in during assembly, and other that you just need some lube on the bearings/sliding surfaces.

these days i hardly use any vaseline, it smokes a LOT, i do use a little, but as little as possible. i use just regular motor oil on all the sliding surfaces, side irons, and rotor housings.

and then i've been using some redline CV2 on the bearings/dowels etc, i know its kind of fancy to use synthetic assembly lube, but its great stuff!

before you start it, pull a fise to disable spark/fuel, you could alternatively leave the CAS unplugged, i leave the spark plugs out too, as it'll eject the extra assembly lube/goo and just crank it until you get oil pressure.
