ive never seen a turbo with only 3 holes

cjwarren4dcivic

so if it as 4 lines coming out of it obe is oil return one is oil supply and the other two are for coolant

Scott-EP

yup. oil feed will be the smallest one. 180 degrees from that will be the return and the other 2 are coolant

Wow dude...if you can't figure out which holes are for oil and coolant, then maybe you should stop everything you're doing with that turbo and start reading about them. Start with the basic how and why they work and go from there. If you don't have a good grasp on how a complete turbo setup is supposed to function, you will have nothing but problems down the road.
