I'm feaking out, man!!! E shaft oil pellet stuck?

Smoke at random times? When and what were you doing specifically? If it smokes after you get on it on spool down, check the turbos. If it smokes on start up more than likely Oil Control rings or OC orings. Would be odd for a fresh rebuild to do that though since both OC rings and orings should have been replaced.

Overheat indicators or Mazda rebuild sticker on MANA motors should not fall off, generally would have to be removed by someone.

Do not think oil will not collect in IC because it is top mount, it has to go through the IC to get to the motor to burn. That is if it compressor side of turbo.
Exhaust side seals will show only in exhaust. (usually seen on decel after hard run shifting) Try at cruise mode, get on it pretty hard then get off throttle, if you see smoke suspect turbo turbine side seal.

Other cause of excessive smoke could be metering pump over injecting oil. Not that common.

Btw Pellet controls oil through the eccentric shaft, feeding bearings and cooling oil to the rotors, some oil does get to OC rings. OC rings act similar to OC rings on a recip keeping piston/rotor cooling oil and crankcase/oil pan gases from getting to combustion chamber. We have to really rely on the rubber based orings which can go through just so many heat cycles. Yet another reason to change oil frequently, dirty oil does not act as a good heat reducer.

Oil control rings also help retain oil in the cooling chamber of the rotors, when they fail the oil drains in to the bottom of the rotor chamber. When motor fires up it burns off that oil, blue smoke on start that goes away quickly. Oil as most petroleum based fluids burn with some color, blue for oil black for fuel.
