Still blowing smoke out exhaust after AOS replacement

[Heiko]

is it white smoke or blue smoke (sometimes hard to tell unless you're standing in it or smelling it) you may have a crap load of oil left in the intake which is getting sucked up under high RPM's, or you have a failed extractor pump in one of your heads causing the oil to get sucked up into the vents to the AOS (once it fills to max it will blow by and go back into the intake) or your oil level in the car is too high (but you probably already checked that). I had the same thing last fall and my extractor pump on cyl bank 1-3 failed.
