Looks good rab. Too bad I don't have that hole drilled and tapped
Trust me ,,, that will be the easiest part of this fix. 
I have a cut on every knuckle.
Smoking issue when using oil pan as return location for turbo oil drain.

Closer and closer.

I have overnighted plan b. In a few hours I will know if everything is going to be smoke free. My drain solution looked really good but it was tilted just a little to much.
So here are the parts I ordered to finish this job. I have no experience with oil scavenge pumps at all. But this was the best one that summit racing had. So my plan is to mount it on the flat plate that the muffler used to sit on and plumb it so that the oil goes into the block drain. I guess you could push it into the pan but dont have to so im not.

Wouldn’t it just be easier to have left it draining to the oil pan and take more hard right hand turns?

Isn't this about the time that some smart a&$ says "we don't have these issues and challenges with the supercharger"?

Get a top mount turbo plenty of height for the line to drain

Yes I guess it is but then some Turbo jerk will say something about more power and it will all go bad from there - LOL

That’s what I’m gonna do. Great suggestion!!

I just run mine 2 qts low on oil, so that oil isn't blocking the drain path at the pan. Problem solved.

No problems with my oil draining into pan, easy when you know how!

Just installed the pump and made one side of each hose. I just need to wire the pump onto the same type of circut that the fuel pump runs on.

So does Mitch, but not intentionally

Ok i got it all back together and started it up and after about a minute the smoke came back. Talk about being disappointed......
I got to thinking that the only thing left was the piston seal in the turbo. But that still didnt make sense. How could a turbo this new and with less than 10000 miles have a leaking seal ring???
So I got up this morning and pulled it back down and removed the turbo. Guess what.... it was the seal and the turbo had been leaking for a while. The turbo has a heat shield that protects the bearings from the exhaust heat. And the oil was built up and hard as a rock.
You all can take away from this whatever you want. But the fact is .... its over pressureizing the seals in the turbo when its trying to drain the oil back into the pan. And this causes it to leak into the exhaust side. And when it starts this you wont see a bunch of smoke because its going to be burned up by the hot exhaust. But..... and here is the but.... its causing grit and dust to stick to inside of that heat shield. And when enough has accumulated it will eat the shaft and ring seal. And that is what im showing you in the pictures.
Guys and gals you have to get the oil back out of the turbo. The oil pan location is just not up to that task in my opinion.

Is that the same Precision turbo that the rest of us are running, or is this the "new and improved" one that kicks out 1200 rwh?

This is the Alpha turbo. Its a 5558 journal bearing.
It is a great turbo. However I dont run the same turbine and compressor housings that the Alpha system usually has. The Alpha system spools way to fast to generate a lot of HP. It peaks way to fast. So i had to make some changes to it.

With all due respect this, and the other photos show coked oil deposits .... lots of possible causes .... not using a class IV or V oil, improper cool down, bad housing seal, extended periods of idling, over fueling, frequent periods of high inlet side vacuum (lots of full boost squirts followed by off throttle), and possible oil return line restriction .....
EDIT: Also after reading your last reply with your changes do you produce any boost at cruising RPM... running a set up that does not have any positive boost at lower cruising RPM then making long trips without the positive pressure needed to keep the oil out of the housing can be another cause ....

Following...
If I remember correctly you had a Hahn turbo.
Why did you switch from the Hahn turbo to the Alpha?
