I guess I posted in the wrong forum so i'll post it again in this one.

Has anyone ever had to have had there KA24De re-built? How much did it cost? Or does anyone know how much it would cost to have one rebuilt? My 91 ka has around 140k on it and has been putting out a slight amount of blue smoke when coming out of first gear for the past 40k miles. I am confused as to whether its the valves or the rings, and it also has that damn annoying idle that I cant fix. If anyone can halp I would appreciate it.

i have my car just rebuilt like a month ago.. it was 1200$ plus labor.. but i only have 127000 miles on it
