i just picked this 86 GXL from a guy that did not complete the TII swap, so im picking up the pieces. I've owned 3 NA fc's in the past but no turbos.

 

that is the turbo oil feed. or rather would be when it grows up

 

technically not a stock turbo oil feed line, an aftermarket one which is missing a critical component, unless you want to rust prevent your engine bay.

 

lyger is referring to a cap that would screw on. specifically a compression fitting cap. common stuff at any decent hardware store

 

well if he's gonna run the turbo that would be the feed line to supply oil to the turbo. hopefully he gave you the rest of the oil line kit that isn't attached.

 

You may want to cap that before you attempt starting it or rolling it over OR it will shower the engine bay with oil.

 

thank you all for the great responses. unfortunately, the previous owner did not include the remaining parts for it. he did include a s5 turbo, manifold, and wastegate assy. i dont know the condition of the turbo. ill take a few pics tonight and post them
