PCV turbo inlet fitting

[Art Vandelay]

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.

I bought the , 45 degree coupling once, from the receipt it is a 3/8" inverted flare female (tube side). It doesn't mark the other side but I believe it is an 1/8 NPT male (elbow side). You can get them without the additional hose fitting, that you have capped off, at the hardware store. The capped off end, I always figured, went to the carbon canister. At least that is where I have mine going.

The capped off nipple is the air return from the boost control solenoid.

Thanks guys. I think I will just cap this off with a NPT plug and put a hose barb in my silicone intake tube.
