bought an 87 lx 2 months ago with a supposed 88k. did a complete tune up, car runs great and am having fun with it. guy before me only drove it once a month or so and never did any maintenance on it so when i got it i had to tune it up from head to toe. anyway, friend was driving behind me the other day and he said when i stepped on it he could see some blue smoke, he also noticed this when i downshifted. when i had the work done on the car the compression checked good, has plenty of power, the oil was full even though it hadn't been changed in a while. i don't think it's burnining oil, and i don't think the rings are worn or it would be smoking all the time. it was about 50 degrees outside that day and at first i was thinking it was from the cold (the car was warm) until he said it was blue. do not see smoke any other time. i know engines at high rpm's burn a slight more amount of oil than regular driving, but enought to see? don't know if it is no big deal or sign of something to come? i dread the thought of a rebuild already, the car runs strong. please advise.
