Need to clean 2mm PCV hole in manifold; in removing the manifold, my shop manual gives step by step, but doesn't mention anything about what to do with all those COMPLICATED linkages between the air filter housing and the intake manifold.

Do all these linkages come off in an assembly? -or- do they just stay attached to the manifold when it comes off?

I can do this job, but I just don't want to screw up any adjustments/linkages, etc.

Any information or tips on cleaning the PCV system or intake manifold removal/installation would be very helpful

Has anyone done this procedure on their car before? What kind of trouble am I going to get myself into with this...
