Chris, 

I think Thomas is referring to the spring/check balls in the crank that block the oil spray into the rotors at low rpm.  The purpose of the oil spray is to cool the rotors.  To my knowledge, there is nothing that inhibits oil to the bearings, unless you consider the pressure relief valve as doing that, but it only controls high pressure.

Nope. That particular EPA "fix" is not ringing a bell. However, the fact that it changed from what it was doing before is a significant concern. 

Do you know of where I may get more info on the retardation. Mine is a 2nd gen. Would not think that would be considered a later model.

Hey Chris,
I figure you've already covered this base but here goes:

Now keep in mind I have not rebuilt my 20B yet but I have read where in the later models of the rotary, they retard the flow of oil until the temperature rises to an acceptable level as part of the measure Mazda took to satisfy the EPA requirements.

Like I said, I'm sure you covered this base by overriding that mechanism, right?
