It's not the plumbing; it's the PCV valve itself. If you get a bad one they will sometimes flutter with engine vacuum. The fluttering causes a clicking sound. It's a long shot but worth a look.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
