Learn from my valve cover gasket mistake
I replaced the z3 valve cover gasket but I think people should know the following if they plan on DIY:
1) Remove all the hoses and wires from the guides found behind the valve cover before doing this install. Specifically, remove the hose from part #12 in the image below.
2) Inspect your air pump vacuum control hose- Mine snapped in half due to being very brittle. (labeled #3 and 4 in diagram)
What was first a valve cover gasket job has now turned into replacing the air pump vacuum control hose part #11657803732
