... and just like that, "Resurrection!"

My only comment on the whole situation:

IF the temps can be kept low enough, using a lean-burn GDI type engine (at around 40:1 or less), and still be able to utilize water injection, either in a 6-stroke or still using the 4-stroke design, how about using self-lubricating bearing surfaces? (IOW - low temps = OK to use Delrin/Nylon/Moly/other materials that don't require oil.)

This way, you get the compound effect, and you can stop worrying about oil and water mixing...

Also - a dry sump system with a water separator wouldn't help?
