hose for turbo oil drain - bricktron - 10-10-2014
hi folks, i'm looking to replace the hard oil drain line with hose and it occurred to me that some of you must have done the same with your crazy installs... the only 20mm (3/4") oil hose i have found rated at all past 100C is High-Temperature/Medium-Pressure Chemical Hose, $31 a foot at mcmaster-carr... is there something else that people in the know use? maybe a smaller diameter is still big enough?
RE: hose for turbo oil drain - Simpler=Better - 10-11-2014
Go to a tractor or heavy equiptment dealer-they should have reels of oil rated low pressure hose that are inexpensive. I think I paid $5/foot for 1" diameter drain line

Surprising McMC doesn't stock something in that price range.

hydraulic repair shop, there are 8 and 20 bar rated hoses, is sold at meter or foot, Hyd hoses are specially designed for oils .
in here we pay 4€ meter. depending on with.
RE: hose for turbo oil drain - swatmugga - 10-17-2014
I like to do the same. Anyone who can tell me what connectors i need on the Engine ?
RE: hose for turbo oil drain - bricktron - 10-17-2014
thanks folks!
it's much harder to find than i expected. there is much more selection for high pressure than high temperature. many hoses are rated 212F/100C and i'm not sure that is enough headroom. i would be tempted just use heater hose if it were. maybe heater hose slipped inside another piece of hose for structural integrity?
here is one of the few that are rated a bit hotter, but for the wrong size, still hideously expensive.

anyone have a better sense than i of the oil temperature in that drain tube?
RE: hose for turbo oil drain - barrote - 10-17-2014
come on , boys , i´ve been using cooling circuit hose from the scrap yard for my return line and still going , and those Hyd hoses 8BAR rated for piping to oil cooler, i had run with 150ºC oil temp , and they still there keping the integrity.
well some folks want to kill a mouse with a .300 mag. well will work well enough.
regards.

you may be right barrote, but how do i try it without risking spilling all my oil onto the road?
maybe a braided sleeve around the heater hose....

Go for oil/diesel rated rubber for sure.. hot oil destroys water hose real quick. I used 16mm 125°C inner braided low pressure from hydraulic shop, it was only 6€/m. And I know it will hold for maaany years.
RE: hose for turbo oil drain - bricktron - 10-21-2014
looking, looking.... is an upper limit of 100C enough?
here is one:

RE: hose for turbo oil drain - starynovy - 10-22-2014
Important is oil resistance.. go for it.
RE: hose for turbo oil drain - Hario' - 10-22-2014
Just buy actual-factual hydraulic hose with your required ID..
RE: hose for turbo oil drain - bricktron - 01-22-2015
hi folks, so i finally had my transmission replaced and returned to this job (pic below).
i cut the turbo drain tube to slide inside the 3/4" hydraulic hose. at the oil pan the hose is too small to fit over the nub of the oil drain receiving tube, and larger than the breather drain port. i put a rubber stopper in the former and clamped the hose to the latter, and it doesn't leak, but the car is now super smoky when the turbo kicks in at low temperatures. despite probably needing valve stem seals anyway, i suspect the turbo is getting oil soaked, not because of any kink in the hose, but perhaps that breather port does not flow well enough, at least when the oil is more viscous.
i tried to cut the receiving tube using one of those rotary knives for plumbing but it didn't work, after managing to slightly score the pipe i realized those cutters are only good on copper. i could use the dremel to cut it but i want to avoid getting any metal filings into the oil. what else can you all suggest? i'd like to avoid dropping the skid plate and lower pan to remove the tube from beneath.

Tee into the blue hose. Even if you need to get a special fitting made.
RE: hose for turbo oil drain - bricktron - 01-23-2015
i made a fitting using the bell of a stock oil drain. now the geometry is kind of funky, because this hydraulic hose isn't so flexible, but the smoke seems abated and hopefully it will keep working.
RE: hose for turbo oil drain - bricktron - 01-23-2015
when the engine got warm the hose kinked up and the smoke returned. now to find a way to hold the hose open. the geometry of the oil drain hard line is wrong for this application: the tube bends away from the center of the diamond towards an oblique angle side, but if it were towards an acute side, i would have no problem. now a lot of the angular mismatch is taken up at the bell end of the tube, which won't sit straight up and down any more.
RE: hose for turbo oil drain - bricktron - 01-23-2015
i found a stainless spring that fits inside the hose and keeps it open. bell cup still ajar, but it seems to seal.
RE: hose for turbo oil drain - winmutt - 01-28-2015
For the record I just used whatever was at autozone that fit and some pipe clamps. Kept the stock drain, cut the pipe. No need for high pressure here.
RE: hose for turbo oil drain - bricktron - 01-29-2015
thanks winmutt, i was really reluctant to cut the pipe and get metal shavings into the sump but i think stuffing a rag into it first could prevent that. probably i will go that direction next. for now the bell is sitting at a funny angle but it's not leaking or backing up, which is an improvement!

Oh you definitely want to pull the pipe out before you cut.
RE: hose for turbo oil drain - bricktron - 01-30-2015
yeah, that would be better, but i have been trying to avoid pulling it out since it can't be reseated without also R&R the oil, sump, and skid plate.
RE: hose for turbo oil drain - led-panzer - 01-30-2015
Not at all man, it's only held in by that rubber gromet.
RE: hose for turbo oil drain - bricktron - 01-31-2015
wtf! i could swear i had read a long thread by someone struggling to lever the fitting into place from beneath, but chapter 18-031 suggests you are right. thanks for the tip led-panzer.
RE: hose for turbo oil drain - bricktron - 02-03-2015
i was all ready to declare shenanigans and that the tube DOES have to be inserted from below, when i got it through. much better, thanks all!
