remote turbo scavenged oil

[Billyisgr8]

I am planning a remote turbo under the cab. where would the best place be to return the oil too.....or the easiest place? Also what happens with the CDR on the turbo trucks? Or is this where the scavenged oil should be sent too?

I returned mine to the vally pan where the CDR was and put a Road Draft Tube in the front cover for the injection pump timing gear, although I have though about running this back into the exhaust whenever I decide what I am going to do, whether it be stacks or a straight pipe out in front of the pass rear tire.

Someone here posted a picture where they returned the oil to the oil filler neck.

the CDR moves to the valve cover on turbo trucks. the best and easiest place to drop the oil back is the CDR valve location, but the front gear cover or valve cover work just as well. you can also drop it in the pan but then you have to pull it and weld a bung in.

Barney did a remote turbo and used his lift pump to evacuate the the oil from the low mounted turbo and pump it back into his engine.

that is i was fixing to say you want the oil to flow just as easily as possible so without havin your oil line straight downhill i would suggest a pump on the return side. I just burnt a turbo up because of a bad return line.

A bung welded to a chevy big block block-off plate will work good for the return if your running an electric fuel pump.

If your return doesn't allow oil to get out faster than it can get in then you are going to be pushing oil past your seals. The way I do it, is always have the return line a couple sizes bigger than the inlet. If it is a gravity return I won't run anything less than 5/8" hose, When I was running a turbo on my old gas motor it had a bend in the return to get around the belt because I was returning oil from the turbo to the front of the pan, I had to end up running 3/4" return line there, 5/8" wasn't big enough a bend it in (hard line for the bend).

In the case of a low mount turbo, It won't do you much good to have a bigger line than what your pump can move. On my remote mount I have 3/4" steel pipe 3 inches long on the return of the turbo straight down with a 90 elbow with a 3/4" check valve and after that it goes to 1/2" because that is as big as the inlet on the fuel pump, mine works fine with no oil past the seals in the turbo, the big pipe down off the return is a buffer area so between pulls of the pump (diaphram fuel pump) there is more room than the oil can easily fill and cause problems, I was probably being over cautious but it works good for me.
