i pulled out a t-5 from and 82zxt(pick a part). while in the process i notice an oil line coming out of the back of the oil pan. does anyone know what it is for?

Dont have a clue what a T-5 is but the line from the pan must be part of the PVC systime . Don't know anything of the turbo engines but , they have an oil cooler could it be a return oil line ? Just a thought . I have a 82 ZX enging but no extra lines from the pan. Gary

the oil feed line to the turbo if it was on the drivers side
