Make your Own Oil Feed/Return

[steve-gers]

I came across this on ebay and was wondering how hard it would be to use it to make your own braided oil feed/return with some fittings and hose etc. Any help or info would be greatly appreciated and yes I know you can buy them already made but there like £60 and I'm sure you could make one cheaper plus I'm on a roll after making an adjustable panhard rod haha.

Oil Feed and Drain Flange x 1(-4AN FEED / -8AN RETURN)

-8AN seems a tad small for an oil return.

Ah right not so good looks like i'll just have to buy one then

-8AN seems a tad small for an oil return.

Its a good bit smaller than the stock hose but since its bigger than the feed hose and as its really on the non pressure side of the turbo it should be ok I would have thought.

I dont know how it would work out with the sump connection but.

Yeah the sump was the only problem I tried looking for an 8AN to 19mm redecer but no luck

You would probably have to weld an 8AN male fitting onto the sump to replace the stock hose spout.

ive seen them.
AN -8 (AN8) Male Stainless Steel Weld On Fitting / Bung ( should be able to find mild steel as well, even cheaper )

I would baffle the sump while you have it off too and inspect for any metal deposits while your there.. It will be quite a short line, the standard oil return is just like a 90 bend, I cut loads off when using a 19mm silicone 90 bend ! still looking for somewhere to use those bits,

are you doing all of em ? water and oil feeds + returns ? should look quality if you do the lot

-8AN is generally used with 1/2" OD hose, 1/2" is approx 13mm so allowing a minimum of 1.5mm for the thickness of the hose wall (personally I don't think that's enough) it'll leave a ID of 10mm. If you opt for a hose wall thickness of 2.5mm that'll leave an ID of 8mm.

Either way that's like trying to drain the oil from the turbo through a tube the size of a ball point pen, IMO it'll create some back pressure in the oil flow and could result in oil leaking past the shaft seals in the turbo. A blown turbo would be an expensive way of finding out that it doesn't work.

Think I'll just go with the safe option and buy one or just cut, drill and tap my current one and add change the solid pipe to a flexible one
