I'm looking for the size/thread of this fitting that attaches the hard line from the valve cover to the turbo inlet. I'm going to replace the oil separator and lines with a catch can and 5/8" hose. I can't work on the car right now because it's in a storage unit, but I'd like to have the fitting ready as soon as my garage is built. Does anybody have this info handy? Also, is the capped off end supposed to go anywhere? It has been like this since at least 2003.
