hey i just got an rx7 last week, its an 89 gxl 5spd. i've noticed that under full throttle when i shift there will be a rater large puff of blue smoke out of my exhaust. the car doesnt smoke anyother time, i was wondering if anyone knew if this was a serious problem or just one of thoes things i'll have to put up with. it would really help me out if anyone knew what was causing this
