What I have heard is that the PTFE RMS surface that touches the crank should be installed dry, but that's not the part of the RMS I am referring to.

The PTFE seals are known to leak easily, even around their circumference, with as little as a finger print on them. Unless the case bore is clean, dry, and free of sealant or other contaminant, they will leak; that is their one major downside, the installation has to be correct, no contamination of any kind. There is a reason the PTFE seals come with a blue plastic ring that protects their inner circumference.
