Just picked up an 89 civic si for my fiance. Drives good and seems to have plenty of power but is blowing blue smoke. I don't know how much oil is burning yet as we have only had it a few days. I know it should be either rings or valve seals but someone else was suggesting it could be jet valves leaking which are replaceable without pulling the head. Anyone know if this engine would have jet valves?
Thx
