Rebuilding Questions For the Gurus
Ok, so this is cross posted from the 1st gen section, but I thought it should go here too since Id love to have tips or tricks from everyone - seeing as this is the one thing we all have in common, the engines!
Heres a copy and past (and link) of what I have over there. Please feel free to leave input in either thread. Thanks!

So, Im about to attempt to rebuild my first rotary engine. Its a 12A that I will be street porting with RB templates, and using an Atkins level C kit for the assembly. I have rebuilt a piston engine or two in my time to say the least, and worked as a mechanic for a few years, so Im sure I can manage. I just have some seemingly silly questions about the rotaries however...
I noticed reading through the FSM that they mention to use engine oil to coat surfaces and such during assembly. When I build my piston engines, I usually dont use engine oil, and instead use engine assembly lube since it "sticks" to things a little better and doesnt "run out" of places. Is it ok to use this stuff in there instead on the bearings, seals, etc that call for engine oil so they will "stick" in place? I really dont see why not, but thought I would ask. I plan to still use oil to coat the housings and plates of course.
Also, I noticed that they talk about using petroleum jelly to hold seals in place on the rotors. Im sure that if I can use the assembly lube, I can accomplish this as well without the jelly. Good idea? I plan to still use the Jelly for the coolant seals and what not since I dont want that assembly lube floating around in the cooling system however, is that how its typically done?
Im sure I will have a few other questions, but these are all I can think of for now. Any input you have would be nice! Feel free to throw out tips or whatever as well. Thanks in advance!

Here's what Ihor and I use:
side plates, rotor housings, bearings, eshaft: assembly lube (we favor the red cling-type)
oil control o-rings, oil pump and chain, tension bolts and o-rings, rear stat gear o-ring: engine oil
coolant o-rings, dowel pin o-rings: Hylomar
corner seals: assembly grease
apex seals, corner seals: nada
Oil pan and lower engine mating surfaces (ie legs of rotor housings etc as per the FSM): Right Stuff Silicone (no gasket)
Front cover: metal mazda gasket
Hope this helps!
