yo can i run my oil return line under the xmember? i dont wanna have it next to the header
it should be touching the cross member when done, not dragging on the ground and its a stainless braided 1/2" heater/oil hose

You do not want your oil return line going 'up' at all. It should return to the pan right above the top of the oil level. If you need it to stay away from the uppipe/dowpipe, attach a 45* fitting on the outlet of the turbo and point it away from your exhaust piping.

uh it shouldnt be angled up at all, maybe a SLIGHT bit uphill but if people can run their return into the pan drain and not have their turbos blow i should be fine w/ a slight uphillness

if you're going to ask the question, and then not want to hear a educated answer...why ask the question?

well if its going under the xmember its going lower than the oil pan tap. you can run it over the xmember right next to the valve cover. it would be a better option than running it under a car, but you dont have to listen to us, we only have the experience

Anyone have pictures of how this all hooks up to the oil pan? This is one place where i'm pretty confused still.

why don't you just tap your passenger valve cover and return the oil there?

so you're concerned about doing the return line from the valve cover cuz you hear bad things about it, but it's okay to ignore the fact that the oil return will be gravity-fed and it's not okay to have an up-slope?

unless i find a different way, the first damned question i asked was about whether or not it was ok to have it under the xmember, but im not going to because incase i bottom out it wont rip the line off

mods plz close this thread

it's "gravity fed", going uphill, for any degree, for any lenght will cause it to stop flow.

going uphill defeats the purpose of "gravity" there's no pressure to make it go uphill and into the oil pan, then it will backup into the turbo and blow out the seals and probably burn up the bearings. just a few hundred peoples opinion on that, but you can try if you want.

the FAT kits go into the valve cover and I've never heard anything bad about it. Also, doesn't the n00b turbo go into the valve cover as well?

I ran mine between the crossmember and the oilpan, and up the back of the head. A -8 line would be good, I used -10 and it was very tight. Like everyone has been saying, you don't want the oil to have to travel up hill at all.

mine is uphill at...id say...POSSIBLY 2 degrees from level for 2 inches, with all the oil pushing down on it, its not going to matter

it _could_ work, but I just don't understand the point of re-inventing the wheel. could always pick up a used ludespeed oil pan, it runs the line outside of the engine mount.

I understand you want to keep it away from the header, but if it's all downhill it isn't going to have time to heat up the oil that much, as it's a pretty limited amount of oil returning there compared to the amount that is returned from the rest of the engine.

my return line is about 4 inches in full length to the valve cover, think about it like this, if you had a ball and put it on a 2 degree slope will it stay in the same place or will it roll away?

think if the ball had a continuous supply of balls behind it, had no raduis change of the tube so that it could flow fine, and was liquid

my oil return is a straight shot down into the pan. your idea sounds alrite since its a really subtile and short uphill but you have to remember that oil is viscous and its not like water so it wont exactly flow really easily, it will thin out at high temps but it still wont flow like water so the uphill part might be a problem.

i think the people had problems returning to the valve cover when they're turbo wasnt high enough above the valve cover.
good luck

I recall a number of people having problems with the Minnam kits because the return line had a very short/very slight uphill section. they shortened the line so that it went straight downhill, and no problems anymore.......coincidence?

the problems they had were oil blowing past the turbo seals etc.


ok, lets think about it like this, if you have a downhill tube, that takes a slight upturn at the end but is lower than the first part of the tube.

now pour something down the top part, when it hits the bottom it will stop and begin to pool and build up in the first section of tube, granted once that level reaches the heigth of the upturned part of the tube, it _should_ equal out (assuming water) but for the backing up of the liquid in the first tube, the air that the liquid is displacing has to go somewhere, it won't go out the bottom so it has to come out the top, burping it so to speak.

now take the same scenario, with an all downhill slope tube, as fast as liquid goes in, it goes out, there is never any backup, and no 'burping' of the tube.

my $0.02

Unless you want a James Bond smokescreen you should make every attempt to have NO uphill sections.

your question was "yo can i run my oil return line under the xmember?"

the answer was NO

just because we gave you a reason as to why it was no, doesn't mean we were getting off topic, just giving a reason for the unanamous NO that was given.

go ahead and do your own thing, it's cool, but don't get all upset when down the road you post a message about your car blowing smoke and somebody throws this thread in your face.
