After half an hour drive I parked in front of my house and started to rev the engine in neutral. I held the rpm at 3000rpm for 15secs, no smoke. Held it at 4000rpm for 15secs, again no smoke. Slowly increasing the revs to 5000rpm, within secs, I see plumes of very light blue smoke coming out the back.
So is this typical of rotaries where the omp is discharing more oil at that rpm or is it burning too rich(doubt it, smoke not blk). I thought if it were the side seals that it would smoke at ANY rpm.

I think as oil seals break down they will smoke more, to the point that it will smoke pretty much all the time. You can have oil seals going bad and it will only smoke at higher rpms, but not all the time. Your symptoms don't sound that bad, do you get smoke between high rpm (7500 to redline) shifts?

I forgot to mention that it'll smoke after 5000rpm, either in neutral or in b/w shifts. Never checked to see if it smokes in a 2nd gear pull to redline but I'm sure it does, w/w/o a load.
Darn another rotary bites the dust

It sounds to me like it could still go for a while, and if it's any consolation, my rx has big time oil seal problems and is waiting on a rebuild.
