That is a 2nd gen specific question. What is tha opening to the left of the oil filter?

Nevermind, it's for the oil filler.

You will find your best answers in the 2nd gen section. That is an S5 TII engine btw, they have a 2 piece, offset oil fill tube.

if you really want to get rid of everything..plug off all of your nipples on your intake plenum, run one vaccum line from the nipple in the center of the lower intake manifold just above the ACV. Run it to a T and one line to the fuel pressure regulator, the other end to the distributor..Y it at the distributor ....if this is still a FB...if you're running S5 stuff then just a line to the fuel pressure regulator is all that you need.

On second thought..this is all you need for a S4..S5 uses some solenoids I believe to activate the 6 ports along with the air compressor. But ya..double check the 2nd gen section.
