I'm interested in how the rotor seals are lubricated in the RX-8. I have ascertained that the "oil nozzles" (as they are called), which are connected to the Metering Oil Pump (MOP) are located in the top of the rotor housing in the general area above the fuel/ air intake (side) ports.

What I would like to find out (if anyone knows) is the point in the fuel intake cycle that the nozzles inject oil. Would it be just before the trailing seal passes under the nozzles (thus hitting the seals more or less directly), or earlier in the fuel intake cycle, thus mixing the oil with the fuel/air mix in the chamber?

the oil comes out as the seal reaches the nozzle.

it is not injected---there is a drop of oil in the weep holes(2) and as the rotor goes by it is wiped off.

It just kinda oozes out :lol2:

Thanks for the info guys.

Yeah, the terminology of "nozzle" and "injector" conjures up images of big charges of oil spraying but it doesn't work that way. I once calculated that at a rate of 1 quart per 3000 highway miles the injectors all told were deliverying about 1 drop per 60 seconds. Most guys are familiar with this rate of flow. :eyetwitch
