Question Oil return questions

If anyone can help me out please do.

Okay so pretty much my oil return line isnt sufficient, and is backing up oil through the turbo into the exhaust at full boost/high rpms.

I got a bigger size line made, but now I feel that the line will interfere with the header. SO I need a 90* fitting. PROBLEM, will that fitting just counteract my larger line?

Can I send the return oil to a small "container" and from there into the oil pan? Will that make it so that there is more capacity / room for the oil to return to a liquid state from the "froth" before it hits the pan?
Any other Ideas that people have

ALSO, if you could please tell me how large the inner diameter is of your return line and if you are having any problems
Thanks.

kian i plan on running -10AN hose for my return...i don't see why you couldn't have a tank in the middle but you are still going to have a gravity feed problem unless you can get the tank to as much of a straight shot to the pan as possible. good luck

Kian, I'm just using the iSR Banjo Bolt return line and it works great. It's inner diameter is pretty thick also, probably around 1/2" to 3/4".

Would there be any issues returning the oil through the valve cover and blocking your current hole in the oil pan? You'd have a straight shot and no exhaust interferance problems, but is this something that can be done?

Kian- Im running a -10 Braided hose into a -8 braided hose after it passes under the block, then into a 45 degree AN fitting and into the oil pan ABOVE the oil line. YOUU COULD always just hve the oil drain ito your passenger side Valve cover breather valve though!

I am not sure where your turbo is mounted but it needs to be as close to a straight vertical shot down to your oil pan as possible. I had the same problem so we rerouted the line to be as vertical as possible. At the same time we reduced the size of the input pipe. I now get no oil whatsover coming out of the exhaust.

thanks for the ideas guys, keep em coming
I found out the pan weld wasnt in the right position on the new one, so I have to have it redone because it hits the oil filter
Im going to need a vacation after this!

The valve cover idea sounds good, but theres no way I can get a straight-vertical shot to the head from the turbo return.

Alpine, when you made the feed line smaller, how small did you go to?

I knew you were going to ask me that. I don't have access to my car right now and I don't remember the exact size of the input. We called Turbonetics and they told us the maximum input size and the minimum output size in order to stop the oil from backing up in to the turbo. Maybe you could call the people who made your turbo and they can give you some guidance.

Kian you can tap into the LOWER part of your Valve cover if you want, not verticle, but that is what Sport Compact Car did on their Blue 98 GC8 project car. Just ideas! And PAY AREG please!
