Help! still smoking after AOS replacement

[nsbst2t]

thanks for the tips. I am going to try to clean the intake system today.

I heard that it is supposed to be harder to remove oil cap if aos is bad but not sure how much vacuum there is normal.

For the suggestions about the oil filler tube i was wondering the best way to test this.
i was thinking of taking the filler tube loose where it enters the engine near the aos.
If I clamp a heavy plastic bag over the engine end of the tube would that work to test theory?
