there is a silver coated tube that is attached to a vacuum hose. it says NF1 on it and it runs to just inside of the manifold, now is that a check valve or what is it? because i noticed oil or greasy stuff on the outside of assuming its a check valve that it may be leaking, and that could also be whats causing my boost problem.
