Author Topic: WANTED: ideas for / pictures of k14 return line on a 1.6 (Read 3601 times)

So - I am putting my return line on my 1.6 motor and ran into a snag.

My k14 return line has a banjo fitting on it that obviously was meant to go into the block....

however, I am not so keen on drilling the block, as I want the option to dump my k24 back on the motor if needed in a hurry and use the factory "return laden" oil pan.

Does anybody have any pictures of a k14 return that they drain into the oil pan rather than the block?

Also interested in pictures of the banjo bolt going into the block.

I am not averse to going completely custom, but wanted to explore the option of factory parts before doing so.

Thanks in advance for any advice, insight, or ideas.

K14 ECO drain hose.

huh --- good call.. part of my dilemma is that I like not to hack either of my existing lines up..

Thanks for the info on the ecodiesel line.. now to find one

thanks kraut.. now does that use the same oil pan as say, the k14 or the t3?

Also kraut, could you post better pictures of the ends?

edit: if it's convenient of course..

That's not a vanagon td return is it? .. does that hook to a us style td oil pan?

Huh, your probably right, cause i never checked. I asked for a K24 drain hose from that German autoparts place in Calif. (that puts those cool TD syncrovanagon engines on Ebay) and they sent me that one first.

Isn't the quantum double female too? I wonder what this hose fits?

I miss my Quantum.

It died in a deer hit. One of the best darn cars ever made by the VAG.

I finally got some info after hours of pouring over hydraulic fittings websites namely http://www.discounthydraulichose.com/

I've made a few discoveries.

All the hydraulic style fittings on German vehicles are of the type "DIN" which stands for Deutsche Industrial Norm .. This is roughly equivalent to the us SAE

FYI DIN has a 24 degree flare face

Another twist is that DIN fittings come in 2 grades - heavy and light.
These 2 grades are known by the industry as FDINLX (light) and FDINHX (heavy).
This grade impacts the thickness of the hole through the fitting, heavy being smaller ID because the fitting is beefier.
*You have to be sure that your hose size is the same between both ends when making a hose up from scratch.

Gates carries these fitting so your local parts store can probably get them but they charge a ton compared to the aforementioned website (almost 25 bucks / fitting at my local parts house).

A typical gates part for an 18mm female DIN to crimped hose
# is G25645 - 12 18

My problem was trying to find the appropriate adapters to go from my 22mm male DIN oil pan fitting to the k14 extension which is 18mm male DIN

I just ordered the reverse (female DIN) for each end for 3/8 hose and I'm on my way. I actually ordered a 90 degree bend and counterpart straight fitting to go in the middle too, but It's not required, I just want to ensure good fit. I plan to take the whole rig to my parts house once I fit and cut hose to length and have them crimp it for me.

FYI, the oil return coming from the k14 is about 3/8 so I don't anticipate any restriction.

Another wrinkle is the type of hose you use.. and it's heat / oil resistance rating.
I ordered a couple feet of Kevlar hose with stainless braid on the outside and a few feet of regular high pressure hydraulic hose..

I've seen people using things like heater hose for turbo returns so I'm thinking I'm safe either way, but oil coming out of the turbo is probably as hot as it gets anywhere in the engine, I'd guess in excess of 250 degrees f on a good day, maybe over 3-400f on a hard run.

Anyway, I hope this info helps someone save some time in the future..

I am pretty sure it's DIN, but not sure what size.. 15mm maybe?

I know that making it bigger than it is can be an issue with over pressurizing the turbo lube circuit. I think that's why some people run restricters.. I think it would be interesting to know what kind of psi is running through the supply line.. I suppose if you were to order parts for the supply side you'd want to match the id of the OE supply line.
