I'm pulling the motor apart, and fixing things the installer did wrong. The location of where the oil return line goes into the pan has always been questionable to me. Does this look like it't too low to drain properly to you. That line is running from a Turbowerx Exa-Pump to the pan. I was thinking of having a new bung welded in where those white marks are up above.
As long as it’s above the full mark on the pan you are fine, when I did my turbo lines(new pan and it was off the car) I filled it with 6 quarts, marked it and put the bing just above the mark

That's an awesome idea. I'm going to put a new pan gasket on anyways while the motor is out. I'll give it a try. In the event it is returning too low, is there an issue putting it up so close to where the crank would be? Just curious.

The pump is really designed to help with low mounted turbos to drain better. Asking it to push through constant resistance pressure from oil sitting in the pan is going to wear on the pump and reduce its effectiveness.
The bung I had welded to my pan fit flush so there is no issues, the windage trey that’s bolted to the main caps will keep the oil under control. I did mine in the Holley 302 pan for Novas and early Camaros

As long as it isn't smoking, I wouldn't worry about it.
Yeah, I'm getting smoking, and when I removed the turbo there was still some oil in it despite running the oil return pump a bit with the car of the yet 4 and clear the lines.
The turbo must be mounted so that the oil inlet -> drain is nearly vertical. There are specs, but its usually less than 13* or something of an angle. It isn't much. That is what I am thinking is holding oil in the turbo, you have too much angle (I cant see, just a guess).
As for the drain. I noted on my oil pan, the oil sits at or above the oil drain. That is because the capacity of my oil system is large (some long oil relocation lines that drain back into the pan cause oil to sit higher than it should). This isn't an issue for the engine when it is running because the pan level will always (should be) lower when the engine is running. So my advice here is that as long as the running engine's oil level is below the drain it should be ok.
And last, the drain location matters, i.e. any oil whipping/flurry/spraying caused by the crankshaft spinning is going to screw with the draining oil. This is why you want a baffled location, so that it can drain without having interference from the spinning/high speed crankshaft/etc... In my pan, there is a trap-door with a hinge that only swings one way (for cornering, I guess) which effectively baffles the oil return from any flurry/whipping action.
Imagine trying to drain and right at the drain you have a blender going... It wont help.
Good info. I think my Canton Road Race pan will have those baffles, but I'll see how they line up with the existing drain and my proposed location. Turbo is mounted with the inlet and drain inline vertically, so that's not an issue.
Thanks again!
