I'll be installing my motor tonight just need to get all my ducks in a row! One of the hose ends connects to the turbo oil line assy off the front plate banjo bolt. The hard line is attached to the turbo oil line. I think one end of the hose attaches to the plastic elbow duct that attaches to the compressor housing nipple.

 

sorry working off memory but the circled hose...I believe should connect to the nipple off the oil fill tube just below the pcv and the pri turbo intake

 

Yep, it attaches to the oil filler neck.

 

Thanks guys! Just got the motor in.

 

Yep

I remember wondering what the hell that was when my engine looked like that
