Blue smoke on extended idle. 2006 4.8is.

and here is a photo of the hole i removed hoses from.. other side is also like this... so after 300 miles this is way less oil that it is needed for a 10 minute buildup for that cloud of smoke i had... so this ruled out i have a problem with vacuum. plus later i have found out i have a smoke coming on left side only... so ... bank no2 is my next step...

BTWDS - if your two pipes are side by side you only have single exhaust with a flapper controlling the 2nd outlet and you need to pull your throttle body to see how much oil is pooled in your intake.
