i think its the oil sending line (too large ) i dont know the an size i forget. its 4.5 cm (the circumfrence ) think its -6an. will too large of a sending line backup the oil in the turbo? seems like it would if not then what else could be the problem i know the return is like 7.5 cm in circumfrence dont know what size. thanks

anything bigger than a -3an feed line will require oil restrictors or you will eventually blow the seals in the turbo

Neukin

ahhhhh!!! not good


thanks

how long before it will blow your seals? if the turbo didnt smoke as much when i first got it and is smoking more now could that be it??

Neukin

just depends on how much you beat on it, id guess, take it easy and should be fine for awhile

Well oil pressure is rpm dependant, so if you always take it easy and dont rev out the gnine, the turbo seals won't see a lot of oil pressure.

i had a -6 feed line and my car start smoking bad after boost.

if i put a restrictor on now will it stop most of my smoking and oil burning if i've had the turbo on for about 2-3 weeks??

my buddy that has a 700 hp eclipse said that he used to smoke and leak oil from his turbo inbetween shifts, and he said it was cause he was getting to much oil pressure to the turbo. he was running the oil line from the oil sending unite and the oil pressure would get to high for the turbo in the higher rpm's. so he switch his oil line to his head and the problem went away. i am haveing the same problem and i about to move my oil line also. only thing that i don't understand about that is i thought the oil pressure would be the same no matter where it is on the motor. but then maybe eclipse's are differant.

No, the main oil "arteries" in the engine are under full pump pressure, but other parts are under reduced pressure, such as the cam bearings or your VTEC solenoid.

The turbo does not like to see oil pressure. I run -3AN with a 1mm restrictor in the feed, and -8AN for the drain.

Some may say that is overkill, but I had problems with the oil before.

Pressure is like voltage...as it passes through a component [read restriction/resitance], you have a drop or "change in potential."

man my seals might be shot if its smoking at idle now huh??? it doesnt at first...i leave it idle for a minute or so and the ****** things smokin like crazy.....any ideas??? still waiting for that restrictor but nto sure if thats going to fix a problem like that???turbo i boguht was brand new only used 3 or so weeks...

I don't Believe they are shot because I had this same Problem. The reason why its starts to smoke after a min or so... is because the oil pressure is much higher in the engine until the oil warms and thins a bit..but with higher oil pressure cause the turbo seals to fail and slip oil into your exhaust then when your DP gets hot ... oil begins to burn off...This happened to me and was told the reason by the guy who rebuilt my trubo...Also he said to use a 3AN feed which controls the volume and I already run a 10AN drain back...OH no more smoke ...People said my seals were gone...NOT...My turbo Guy said the seals are like piston rings so if they are bad they are always bad. Trail and Error is how you get through these problems.. Hope this helps...I need to post the some pics of the difference between the 4AN line and the 3AN line, a big difference in volume not so much the to lower the pressure. But its more of lowering the volume of oil that solved my problem. bump

sounds like your talking more about current than voltage.... Sorry, that just bugs me

turbo'd integra LS

well man i just put on a restrictor and im running a 3AN line...whats a 10AN line in inches?? My line is 3/4" on the return....i was told by someone that i could have floated my seals in the turbo and messed them up? what oil you runnin?

Current is equivalent at each point in a series circuit [no matter how much restriction there is]. Voltage drops through each restriction in a series circuit and then increases at a place where energy is put into the system [like a battery, or oil pump], so the sum of all the voltage or potential drops is equal to zero.

Not really. The way he used it sounds nothing like current. Dax is right about the current being equivalent in a series circuit. What is not right is saying that the oil flow in your motor travels in a series circuit. It’s a compound (complex) circuit; it has both series and parallel junctions.
Actually the turbo feed/return lines are in parallel with the rest of the oil system AFTER the oil feed port. So the current/flow would not be the same throughout the system. That is what you want!
If you run a smaller line than there will be more resistance in the feed/return lines witch will result in less current/flow through the turbo lines witch will use/see less voltage/oil.

Hope this helps

where to get these restrictors at?

Not truely sure on the size comparison of a 10AN. 10-30W synthetic oil...Are you still smoking after burning off what excess oil was left in the DP?

turbo'd integra LS

it just smoked a little this morning (the first time i drove it since the resitor was in place) just a little...but my a/f guage is showin rich at start up...but i didnt clean the charge pipes so theres still oil in them....so after i do that i'll have to check er out...im hoping there wont be no oil!! how much oil you go through now??

turbo'd integra LS

oil restrictors can be found at this site...

I'm not sure what you mean...I know you shouldn't be using loosing oil if your problem is fixed. The oil I loose is caught in my perrin Oil Catch can. PCV...

i was using a an6 on a t25,smoked like crazy,couldnt stand it.switched to a an3 and now it only smokes on hard acceleration,but that could also be the old oil still.going to a an3 made a huge difference.
