But at low speeds or between shifts there is not enough suction/flow out of the turbo so you get oil creaping through the seals in the turbo. At that give a little puff of smoke through the exhaust. The best way is up high in the top part of the pan. That way the oil will just flow out of the turbo & into the top of the pan above the oil in the pan.

i ran a -8 return line directly into my pan with absolutely no flow problems.. welded a -8 JIC 90deg fitting facing backwards to the "side" of the pan. proper return line sizing is more of an issue than where the oil flows to.
