on the stock twins you know the hard pipes that come from under the oil filer neck and one of them goes to the turbos and you have to use 2 wrenches to get them off that is one of the 2 lines but what does the other line go to? I can recall what the other one goes to! thanks

That is the oil feed line. It splits into two on the turbos, then the drain back is two separate oil return lines at the front and rear of the turbo.

 

Thats right so each trubo has it own oil then its returned through tthose pipes at the front and back! thanks jeff!

 

Its part of the crankcase evac system, there are not 2 oil feed lines at that point (until they split on the turbos).

 

IT goes to the nipple on the elbow on the pri ,front turbo intake plastic pipe ( black ,bolted to the turbo compressor housing ) .
