I assume you are asking about the check valve that the rubber hose to the intake connects too. It can be replaced. If you replace it I would replace the rubber gromet for it at the same time...

Yep, brake booster check valve. It is replaceable. Easy to break 'em while removing them.
477.611.933A for '87
191.611.933F for '84
rubber seal for both:
911.355.921.00
Porsche dealers, or other vendors should be able to supply these easy enough. Above numbers may have been superceded also. I cheated, I looked in PET.
