Strange Problem
 

I just finished rebuilding 7mgte turbo JDM motor, metal headgasket, ARP studs torqued to 82, block and head machine lapped to near perfection. Engine runs great, good oil pressure (40 psi@ 2500 RPM) no overheating problems, temp gauge rock solid. BUT I am getting oil in the radiator and overflow bottle.....however not a single drop of water in the oil. Second problem....when idling after driving for awhile (engine warmed up) I get a good size puff of whiteish smoke. Rebuilt turbo , compression check good all cylinders between 165 to 170 . Any help would be appreciated!!
