well, the quick run down - i did several back-to-back oil changes, with 5w-40 castrol synthetic, used engine flush before the oil changes, and used auto-rx inside the engine, and changed the filter in the middle of the oil cycle (oil filter changed every 3K miles, oil changed 6K miles)... this reduced the blue smoke a little bit and somehow improved the MPG of the car... but it did not eliminate the blue smoke...

i was wondering if that IDLE SPEED CONTROL VALVE information is of any value...
