Blue-ish smoke from exhaust
i just wanted some feedback.
its a sohc KA. had a rebuilt, resurfaced head, new valve seals/guides about March 08. also new headgasket. its not blowing a lot of smoke only when im at full throttle around 5.5k-7.5k rpms. not overheating AT ALL. still pulls strong. if i drive normal theres no smoke at all. when it does smoke its kinda blue-ish. im thinking piston rings since the block is at about 190xxx. but what about 02 sensor or fuel mixture running rich. i know it cant be the valve seals or head gasket. also, it doesnt seem to be losing much oil( even though the oil pan is kinda leaking oil)
any ideas?
