hiya guys, the the size of the fitting which you weld into the sump?
im having my pipe custom made but i want to make a start on making the sump as it will be one of the first jobs i do.
what did everyone else use? any links to products/ ebay items would be great.
only post up what you used as i dont want guess work;-)
cheers

Mines the oem passat drain pipe with the bottom section cut and re welded to suit the length, then a flat plate welded on the sump with two dome nuts for the flange to bolt too. The oem pipe is realy good solid either end with a flexi in the middle and a flat two bolt flange either end.
-
Can you get a picture up of the above Anthony?
-
I used some 16mm ID (from memory, same as the OEM ID anyway) tube that was already bent to the correct shape, cleaned it up and brazed it into the sump. The turbo-end was a cut-down OEM pipe joined with some rubber oil hose 2mm ID too small to ensure a tight fit clamped with jubilees. No leaks :)
The sump-end of the tube was a piece of old deck-chair :D

Can you get a picture up of the above Anthony?
Will get some photos when I next go to the garage, although you have to excuse the instant gasket over one of the bolt heads on the flange as me being the monkey I am overtightened the bolt and striped the thread :(

Here's the sump fitted with a blanking plate after it was powder coated.
-
looks to messy for me, im an sad perfectionist.
ive got a 3/4" BSP fitting im going to weld to the sump now and use a custom made line
-
I would prefer a fitting welded on aswell, when I change turbo I will go this way but I do like using the oem line as it's mainly solid and good quality and isn't too pricey to buy or replace.
-
I just welded a fitting to my sump:

-

-

-
yer i seen that.
made my own lines now so when ive welded it all in il get some pics up
-
Sorry to hijack, but where do you take the turbo oil feed from?
-
Back of the head, where the oil pressure sensors are. T-piece into one of them. M10x1mm thread.
-
Lovely, thank you very much.
Why do you need to tap/attach a return to the sump? Why cant you use the normal oil feeds/returns on the g40 block?
-
Not wide enough, both the feed and return are too narrow for your average turbo.
-
Yup you need a large return line otherwise the pressure will be too high and the oil will back up and push past the seals in the turbo, leading to a schmokey exhaust!
I used an AN-10 fitting to the sump and got it TIG'd on the inside so it looks alot neater.
got all my fittings and hosing from torques.co.uk but through thier ebay shop

-
Sorry to bring up this old thread, but can anyone confirm that the AN-10 fitting is the one for the standard oil return?
-
im running a T25 btw not a K03 which I think you are planning on?
-
Yeah, hmmm hayesey has posted what looks like the A10 and he's using a K03 like me.
these are the return feeds i've got so I've got a choice

Screw fit is the ideal one but I don't know the male fitment
-
hmm, I think it's AN-10 yeah, it's too long ago to remember properly!
Although my drain pipe is a PSD one anyway so may or may not be the same fitting as comes off a passat or audi a4 or whatever those are off.
-
The screw fixing is a custom job which looks like the female AN10 but for the sake of 3 quid of ebay worth a shot with the male AN10
-
actually it could have been a JIC fitting now I think about it. I wonder if I still have the order email from Think in any of my email archive folders, I'll have a look.
-
ha well that was easy, found the emails from/to Think-Automotive from 2008 and it has:
WOS7-10 : steel weld on -10JIC fitting
but as I say, this is for a PSD oil drain so perhaps not the same as yours. There is a way of telling the type of fitting by going off the angle of the seat inside the fitting but I can't remember exactly how to.
-
Cheers Paul,
ill have to browse around see if I can find some info on figuring out the fitment!
Here is a better pic if it comes back to you
(http://i137.photobucket.com/albums/q236/etches69/8950dfc5.jpg)
The cap is 1ich deep or 13mm , threads are roughly 1.2-1.4 mm apart
-
this might be of some use:

I'd probably hazard a guess at JIC though. To be fair, you could just buy a -10JIC and AN-10 fitting from Think, they aren't expensive. A quid or so each more than likely.
-
OK well doing a bit of googling and reading, JIC and AN are the same:
http://en.wikipedia.org/wiki/JIC_fitting
So just order JIC-10. That fitting you have definitely isn't BSP anyway.
-
Cheers Paul shall know by next week!
-
Did anyone ever confirm the size of the fitting needed?
-
An 12 dude, I ended up buying the 10 then the 12 lol
-
Cool beans, cheers.
