Rear rotors go First?
It seems to me that the rear rotors seems to go first on Rotaries. Is that true? If so, why? My rear rotor went a few weeks ago, hopefully this motor I am looking at in the JY is good. I dont want it unless its got at least 100 psi on both rotors.

It's due to the fact the rear rotors coolant Is much more constant (hotter) than the front. Remember, the coolant follows the U path and finds It's way back to cooler temps In the Rad and repeats. The U being the bending point of the direction of collant flow and where the rear rotor Is. Thus, most likely to go, due to excessive temps.

also, the oil flows front to back, so it's hotter (and therefore thinner) when it hits the rears.
I think the rears just get screwed on everything.
I wonder if it's the same on 3 rotor engines?

Actually, you're wrong. Oil flows from back to front.
After the oil sucked by the sump, it goes goes through the oil cooler, then to the back of the engine via the external hose. It then goes through the filter, then first hits the rear rotors gears/bearings before travelling to the front housing.
So, the coolest oil is actually at the back of the engine.
