PS, one of the things engineers like about the Delco 4 is that it can be run in any position..... It can do this because it HAS NO Chamber for holding oil.. it is lubed only by the oil flowing with the refrigerant....
The Yorks can only be run in two positions...
I do not know about the other rotaries.. but suspect they must be horizontal...

I once heard from a MB master tech that the orientation of the R4 was critical for proper lubrication. But above quote from leathermang suggests otherwise.
