Vacuum in the rocker and oil in the engine bay help
 

Hi all I've got a b6 1.8t a4quattro I've got a vac in the rocker oil all over the engine bay and fault codes as long as my arm but the car idles sweet as a nut pulls well no smoke fault codes are misfire all cylinders etc

wtf does vacuum in the rocker mean....?

When you take off the oil filler cap it is sucking I've solved that problem but now it is sucking from the dip stick funnel any ideas ?

how did you fix the other problem....?
