The small pipe at front off the flex hose - Is this small pipe suppose to have like a large steel washer reducer in the pipe? And in the other end of the small pipe their is like tiny bottle brushes inside the pipe? Does anyone know are these suppose to be their or has someone put their for some reason? Link fond on site to show which pipes I am talking about. Thanks http://www.thumper300zx.com/z32/boostleaks/pcv_system.jpg
The little barrel with the hole in it is a restrictor... and the "bottle brush" is a spark arrestor. Both items are factory fitted.
