My 87 turbo was not capped, eventually I capped it, then I began to think about it. Probably 95% or more of most folks driving is not in boost mode so vacuum is pulling oil vapors into the intake and keeping oil condensate out of the turbo and intercooler. When it does go into boost the fitting is restricted so that only minute amounts of pressure enter the intake side. And where does the pressure go? It's added back in just ahead of the compressor wheel.
I cleaned out the fitting and hooked the line back up.
