Hey guys, recently took my turbo buld out for its 2nd test drive after installing a kit and I believe I smoked the turbo seals due to it not draining properly. I have oil coming out the middle of the body of the turbo. I wanna install a scavenger pump to help with the draining. How are y'all mounting the pump and what are some helpful install tips? Thanks for any help and guidance.
The turbo does not have actual seals that can blow out.
Make sure the drain plate gasket is not leaking, usually when the shaft seals leak the oil comes out the exhaust or out of the mounting flange of the compressor.
As long as the drain has vertical slope and is of sufficient size, you shouldn't need a scavenge pump.
Also make sure your engine crankcase is able to breathe sufficiently because that will affect turbo draining.
If your set on the pump, mount the pump close to the turbo, the turbo drain can go straight to the pump although having the turbo drain into a small tank mounted right under the turbo and then having the pump pull from the tank is highly recommended.
Gotcha. I saw it leaking from the v band that connects the exhaust housing to the body of the turbo. I already bought the pump and with how the roads are around me I'm just going to run the pump. I don't really see the harm of running it and its a nice piece of mind. It's more a cruiser/street car than a track car

Yeah, definitely oil is backing up in the cartridge.
No harm in using one, just one more failure point is all.
The other thing you could do is add an oil pressure regulator for the turbo, Turbosmart makes one.
Here's a pic of the tank if you end up needing to go that route. The tank ensures the oil clears the turbo cartridge and then the pump pulls from this.
Something isnt setup right, sounds like your masking the problem with a tank. It shouldn't be blowing oil of of the v band, do you have you turbo clocked right? What size drain line do you have? Is the drain on a downward slope? Do you have a catch can setup on this vehicle? Are you sure you don't have crankcase pressure building up and blowing out if where it can relieve itself?

That's a nice piece. I have read about the supply restrictors, I may install one if the problem continues. I was gonna add an inline Hobbs switch from the outlet to the pan and run it to a little light so if the pump does fail I'll have an indicator for it

well it smokes only when I was coming to stop on a downward hill and my drain isnt the greatest. The turbos clocked completely level according to my digital level indicator. The drains your standard -10 line and the lines on a downward slope. The catch can is -12 lines from the valves covers to a vented catch can. Had plenty of vaccum on the setup. On straight flat road hits nothing but smiles and clean burn, coming down a hill and breaking i get smoke. My drain isnt the greatest because it favors the passenger side of the pan but my hookup is on the driver side. There wasn't any room with my setup to put it on the passenger side unfortunately. So it wraps around the mounting flange and then aling the side of the pan. I dont have any pics on hand of it all finished
