Can oil lines be too long?
 

so i found a good deal on some -4an ss line (3 feet) so i can adjust my restrictior from the engine bay, anyway i have steves oil kit so now i have like 6+ feet of line :o when you start the car the oil should reach the turbo pretty fast still right? i know its a n00bish question but i just want to be sure, i know it will allways bother me if i dont ask :-[

i'm sure it will be fine, but why not just use the 3 feet?

Re: Can oil lines be too long?
 

becuase the restrictor is between them

Re: Can oil lines be too long?
 

why not put the restrictor at the end of one line...

You'll be ok. The oil might take .000000043 of a second more to get to the turbo, but when you start up the car it will be cold, and more than likely won't spin until you gas it anyway.

how do you know if you need an oil line restricter?

Re: Can oil lines be too long?
 

well sometimes your turbo might smoke and that could cause it, also getting a oil pressure gauge will tell you if the pressure is to high also.

my still smokes bad out of the dp :-\

turbo have any play either of the usual directions? do a compression test maybe you toasted some ringlands.

as far as restrictors go, its really a case by case basis. MY 14b does fine with the line wide open, while other 14b's smoke without it. Its kinda hit and miss with those fuckers.

i think the seals are fucked too, oil leaks out of it! oh and no in-out play, very little side-side play...hypothetically typing, if my ringlands are shot around what psi would they be around?

Re: Can oil lines be too long?
 

most cases, one or two cylinders will test significantly lower than the rest.

you should test with solid 180-210 range on a d16, with it warm and at WOT. BBKA's d16 with 100K+ still tests 190psi in all 4, mine with about 8K tested 210psi in all 4.

Deviation between all 4 should be minimal, if they've got 30psi or more difference between any, thats not so good.

Re: Can oil lines be too long?
 

Probably not the best idea to run oil into the interior of the car. Just adjust your restrictor per StealthMode instructions, and you'll be good.

It's basically this...start with the restrictor wide open, and gradually close it down until the smoking stops.

sidenote - if you have to close it all the way before the smoking stops, it's prolly time for a rebuilt turbo. (just kidding, never close it all the way)

what if your return line is a lil too long? mine kinda goes down below the drain fitting on the pan...is it ok to just leave it, or should i cut that bitch? only thing is its gonna be a hoe to get the oil return line off the turbo cuz the way its mounted... :-\

Re: Can oil lines be too long?
 

It should be setup so it is downhill all the way to the oil pan, otherwise oil can puddle in the line and cause restriction and smoking...
