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?

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:

Quote
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.

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.

Did anyone ever confirm the size of the fitting needed?
