Turbo XS manual boost controller issues - 3000GT/Stealth International Message Center

The car is a 1991 Vr-4, I've had it for some time now but just pretty much got around to modifying it engine wise.

I have pressure tested it and the only leak seems to be coming from the manual boost controller, it comes out of the little black rubber washers in it,

Is it supposed to do this or do I have a faulty MBC?

i would see if you can replace those o- rings ..at least that is what they look like in your pics....all MBC are a controlled boost leak...they have what is called a bleed off vavle...i dont remeber the exact reason why..but they all have it..
