Default Mazda rx8 newly rebuid

Hi i m new here
hope you all are doing good
i just rebuild my mazda rx8 engine as i m a mechanic and know much about rotary engines but not a pro.....checked for the compression its 80 psi in rear rotor and 85 in front rotor before it started up for the 1st time.... i started the engine it took sometime for the 1st start but when it started it has white smoke from exhaust and it was not idling to i had to keep pressing the throttle for around 3000 rpm and then suddenly it started backfiring after 5 mins and then it stopped i pull the spark plugs they were wet and it has oil in it cleaned them and deflooded the engine started it again for around 10 min then the same thing happen again same backfires and it stopped but the oil is still coming from the exhaust it is not too much when engine is on higher rpm when the engine tries to idle the smome excess and then if i hit the revs it starts baclfires the smoke is not coolant one it is the oil because engine is loosing oil as well .
i read about oil seal as well but in my case it doesn't look like because smoke stops at higher rpm..
is it fine ??
is there anything related to the timing?
oil metering pump? Is there any timing as well?
i m trying to figure where i m wrong even i have better compression to start the engine .
any help will be highly appreciated
