Turbo oil return - could this work/starve oil???

[PaRaDoX]

hey,

when running the oil return, does the return have to be in the sump or is it possible to run it somewhere else...

any do's / donts when welding the dump??? i know your supposed to have the car stone cold, so that when you weld it she dosnt go bang due to welding gasses

anyone else run their oil lines into crazy places???

My mates VLT has the return running into the dipstick tube.

[PaRaDoX]

yeah thats where luke said,

my mates old man whose doing my welding said could do it in the rocker covers but then it might starve the engine of oil...

how much extra oil should i add for the turbo, i'd recon like a extra 500ml...

im flushing the engine/doing oil filter when i drill the dump to avoid metal shavings from ending up in my turbo bearings

i reckon teh timing cover is the easiest. then tap a fitting into it. that is what i did.
my uncle told me another way. get a centre punch and punch a hole in the sump big enough for the pipe in. then use some glue stuff that stands high heat and sets like metal. paradox, you were telling me about this stuff too..

not really sure on this it's just a suggestion but, could u get a 90 degree fitting or even a t piece that would screw into the sump plug and run it that way?. like i said im not sure on this, just the first thing that came to my head. As for welding the sump i would get a bit of 6mm plate and cut it so there is 10-15 clearance on all sides of the hole and drill and tap a hole in that then drill a hole in the sump and weld the plate on so the holes line up. but i would rather weld it with the sump off.

the problem with that is, the return/dump must not be submerged in oil in any way, if it was it wouldnt flow at all. so like people have said, either weld a fitting at the very top of the sump, dipstick or rocker cover is your best bet. Out of curiosity where is the pickup?

[defa]

that is another reason why i said teh timing cover. then ya know that is is high enough. mine working ok so far

[PaRaDoX]

i got speed flow fittings + steel braided lines

the pick up is off the oil sensor, got a t peice

[Calais_5sp]

paradox, can you post up some pics of your oil return when you finish doing it. still trying to work out the easiest way of making a return for my setup aswell.

[PaRaDoX]

sure can, ive already got the weld on fittings, so i think ill jsut weld the sump

BTW i already knew to drill it high and not submerge the return line :P

[PaRaDoX]

my welder says the sump is too thin, he dosnt want to risk melding holes in the sump

im going to drill it and use some JB weld compound (cold weld) its good up to like 500deg

Find a new welder.

[Blown V6 Hatch]

JB Weld??? You have to be kidding me, right?? Let me get this straight, if that fitting falls out, its bye bye to engine & turbo correct?? Mate, do yourself a favour and do it properly, and save your self the heartache!

A VN V6 sump to thin to be welded with a MIG? I have cut, modified & welded v6 sumps with a MIG no dramas. All he has to do is set up the welder correctly and it will be done in 5 minutes! If your welder thinks a v6 sump is too thin to be welded he doesnt know how to weld mate.

is there some sort of restrictor in the line somewhere. a direct feed from the pressure side of the pump unrestriced will remove a lot off oil from where it's needed in the engine

the feed line i believe is the restrictor, the return line is atleast 2x bigger than the feed line

[Furious_8]

The oil feed is only 3.8mm ID hose if a oil pressure problem arises you can weld the steel fitting on the oil feed flange and dirll a 1.5mm hole and it will gain about 5 psi at idle. als use a 20-40 oil also

[PaRaDoX]

ahh i went for a 15-50 synthetic, oh well it'll still work and protect it quite well

my manifolds will be complete tonight, drilling sump tonight aswell, and might have it running tonight... or tommorrow

[SweetWagon]

sounds like your really close, whats happening with the exhaust off the back of the turbo? who's takin care of the tune side of things? Good luck with it

[DAMO_5L]

ur welder man must be **** then. cause i weld tilt trains for a living and i weled the oil return to my sump on my 5L and it didnt burn threw at all. just make sure u weld it with as little heat as possible

[PaRaDoX]

now now play nice, hes never welded a sump before, he wasnt sure of the thickness of the sump OR the Fitting as i didnt have it to show him, i took the fitting over last night and he said it wouldnt be a problem to weld the entire fitting on as they're is enough thickness to concentrate the heat onto it insted of the sump...

ok tune side Greenfoam said he'd do a tune.. just when im ready, from the base tune im hoping to learn a thing or 2, i have all the chip making equipment already to go so that isnt a issue,

ok, ive got money for a 3" cat back exhust atm and i might go down and get one this weekend, then im going to go for a 3" magnaflow cat converter, the exhust off the back of the turbo? its called the dump pipe and its getting there, its a 3" pipe to the cat converter (slightly bigger than the compressor wheel..)



2 welds to go, BOV onto intercooler piping and wastegate into dump pipe, expecting manifolds done tonight, then clean up the welds, and paint it (black or something)

sumps getting welded on Saturday and ill plug it up untill sunday when shes going in (or saturday if i get time and feel like it)

my 2 bar map sensor arrived yesterday, ive got 14 turbo clamps and 1x180deg 2.25" bend waiting for me to pickup and thats the last of it... it should be done this weekend

[Calais_5sp]

just wondering if you had some pics of your oil return in ur sump, just to give me some idea of which way you done it.

[14secvp]

Into the top or side of the timing sounds like a good place cos then the chain even gets some more oil

[defa]

it works good for me..
