Hey gays,
I need some assistance, I have to install a scavenging pump on my turbo. I don't have a sufficient angle for a gravity setup. So, I have seen mixed answers on electric pumps. Some people are using reservoirs after the turbo but before the pump, some people don't. The idea with the reservoir is to help prevent the pump from "sucking the oil from the turbo" or if the pump fails it gives some capacity for oil.
What do you guys think, a reservoir or not? I was thinking about using a -10 an inline fuel filter housing as a reservoir. Then I wouldn't have to fab anything up, simple fittings and I'm done. Apparently Precision turbo has recommended this to several people. But then I see some reservoirs with breathers on them... I'm stumped, please help.
Yes, but with a 12v electric scavenging pump to pull it from the drip tank to the engine. My turbo is mounted a couple inches above the oil pan, but approximately 8 inches in front of the engine. Here is the turbine housing after I pulled it off last night... Not good

On my car, if I don't run a reservoir between the turbo and pump, everything is fine until you shut the car off. Then the turbo fills up with oil and it leaks out the turbine while it sits. If I put a time delay relay on the pump so that it keeps running for a couple minutes after shutdown, problem solved. Or, if I do a resevoir, problem solved. I did relay first, then did both relay and reservoir, then just reservoir and it's been fine. I have pics of my stuff in my build thread somewhere. I use a BMW oil pump now.

Do you think an inline fuel filter with no element would be a sufficient reservoir? If my math is right, it should hold roughly 5.4 oz of oil. I could also install an inline check valve to the feed. So once the engine is off it won't drain the feed line into the turbo as well causing even more fluid to fill the bearing housing .
Here it is, I decided against the fuel filter idea. Mainly because I am cheap so I made a little deal that holds 1.5oz of fluid. Also this is on a toggle switch, so I am not too terribly concerned with the volume, I can also run the pump after the engine is off. The pump was surely bigger than I expected, I went with the Tilton continuous pump. Run some wires, tighten everything up and check for leaks.
