Thread: Braided oil lines

I need to re-do the feed and return lines to the turbo. They both leak a little, sometimes a lot.

I have the GFD oil feed line kit, but I need to use something other than the banjo fitting on the front of the block. Maybe a 90* brass fitting right off the block with some pipe thread tape/dope, would suffice. I have a leak here, as well. The brass/nylon/aluminum washers aren't working (I've tried them all)

Also, I need to redo the return line. It's kinda looped right now which I'm not comfortable with. I want to run a brass fitting from the block, via braided line to the turbine. Something that won't kink, and is flexible enough at the same time.

Thoughts?

Are you planning on tapping the block for the brass fittings? Brass fittings are NPT which really don't fit well. Banjo fittings are your typical metric threads (like a bolt with a hole ran through it). I ended up getting a 12mm banjo that had a -3an male on the end of it. I got a braided brake hose and sleeved it with high temp. I got a restrictor off of ebay pretty cheap and I don't have any leaks whatsoever. As far as my return I ended up making my own flange to fit the turbo and drilled and tapped it to fit a 1/2" NPT hose barb and ran a hose from turbo to block. I smeared the flange with copper gasket maker...hope this helps tek

want to make me one for my top mount turbo setup or give some details and pictures would be amazing.

Hey Sammy,

I'm running a braided line for the feed already, it's from AN to banjo, but because of where the turbo is located, it's a real bitch to get tight enough to where it doesn't leak from the banjo at the front of the block. Practically impossible, I guess you could say.

It's a bottom mount turbo manifold, and with a very large turbine, so the placement of the return on the block vs. the return on the turbo is REALLY tight. I can't just use regular rubber hose, as it will kink.

Lets just say that I need something strong that wont kink, yet flexible enough for me to maneuver it and still allow for oil draining from the turbine.

Good eye on the NPT thing, though. I hadn't even thought about the differences between NPT and AN. Makes me wonder if I can get some AN 90* plumbing Wondering what the return is, as well.

Quit being lazy...c'mon tek pull the mani and turbo off and tighten that mofo...haha Mine was a pita to get to as well but i got it...no pain no gain.

post some pics tek, let's see what your twirkin with...I've got a buddy that works with hydraulics and air lines things of that nature, if you give me a good idea what you need i'm sure he can come up with something.

Don't have any pics of the new line but yea, i'd be willing to help you out. Send me some pics and some info on your set up and i can work something out.

I'd post some pics, but I'm not at home with the car. It's about 3K miles away from me

Maybe if you could search for my threads of the build and whatnot, it will give you a better idea?

I know this really doesn't explain much:



Hopefully it gives you an idea of how low and close to the block the turbo sits.

I'd say there's about 2" from the end of the feed return flare to the compressor housing of the turbine, or thereabouts. It's pretty damn tight, to say the least.

So this is what needs to be done:

Feed line - Remove banjo, find AN 90* correct size, for both braided line and block.
Return line - Remove flare, find an AN 90* correct size for block and replace fitting on turbo. Fit with braided line.

Now to find the correct sizes, and a place online that sells tons of AN stuff.

Thanks

yea, it is really close...pretty manifold though...turns me on.

so...you're wanting to take the barb fitting out of block and replace with an -an?

even if you only have a couple inches, I still think your best bet would be a 5/8 ID hose. It may be a bitch to get on but it should work fine. It would really really be a pain in the ass to try to thread something when you only have 2" to work with and they don't make braided lines with fittings that short. You would have to make your own, and then you are talking about buying the press to put the fitting on and all. You may be able to check with earl's performance and see what they have...or Roadrunner Performance maybe one of them can make you something that will work.

Nice manifold! What is it?
