There is a valve in the e-shaft = that reduces oil to the e-shaft when it is cold. Bruce (and Tracy?) = sell a part that holds this valve open at all times. It can stick and = ruin the engine. If this engine was built by Bruce, it likely has this = mod.

Again to be sure that the pump is = at fault, you should check the first place you can see oil after the = pump. That is the outlet from the front plate, not after the filter! Looking = there introduces the possibility of hose, filter boss, and filter into the = mix. If the hose is lifting a flap, you will not see it by looking into the = hose because it could lay back down when the oil stops = flowing.

I think your referring to the = e-shaft oil jet modification. I have the mod and low oil pressure at idle and low = rpm's. Mid-20's at idle when the oil is warm. Pressure comes with rpm. =

Chris,
I'll look it up when I get home. Tracy mentions it in his book and it's in the Bruce T. Video.
(most likely someone will come up with this in the meantime.)

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?
