Lets talk oil return lines
My turbo sits so low and close to the oil pan I'm having a hard time routing an oil return line. The turbo does sit higher than the oil pan but it's close enough that if I mock up two -10 AN 45 degree fittings, one on the turbo and one on the oil pan, they overlap each other. Those fittings are just so giant and take up so much space.
I'm thinking about just getting a brass barbed fitting and putting that in the fitting on the bottom of the turbo and clamping on some hose but the oil pan side is where I'm not sure what to do.
Where can I find an aluminum bung of sorts to weld to the pan so I can thread in a brass barbed fitting? The one that came with my oil line kit has male threads for the AN fittings to go on. I'd need female NTP threads.
Thanks for any ideas or pointers.

Yeah it sure is. Not only is there no space for hose between the fittings but my AN fittings actually overlap each other. Although my AN fittings seem much longer than yours. I got them in one of those generic ebay return line kits.
I wonder if I can find shorter ones like yours and try to make that fit. I did order a couple 90 degree fittings from summit earlier in the week that are suppose to be here tomorrow. I was going to see if there was some way I could get them to work but it's not looking good. That's why I was thinking a short barb with some hose and clamps.... as much as I despise that sort of setup that's bound to leak at some point.

Possibly, but you CANNOT use 90 degree fittings on your return in any part of that line. You'll cause a oil backup and pressurize past your turbine shaft ring... eventually damaging it. In fact, with your PRecision turbo, its grounds to make any warranties voidable. THIS IS THE TRUTH, I'm not playing any d!ck games with you on this.. DO NOT USE A 90 Degree fitting
Your idea of the 45 degree brass fitting is more practical idea than using any 90 degree fittings.
Here's the fittings I have.

See how big it is. It goes down so far.

Now look when I mock up where the other one would go.

That's why I was thinking super short barbed fittings but I'm open to suggestions.

Its not the fittings, its the collector of the manifold relative to the fitment of the turbo that sometimes makes proper fitment into the pan a PITA.

That's where you could put a SMALL section of braided line into a weld bung to go into the pan. Damn e-bay Earl's knock-off fittings.

My plan with the brass fittings was to just use straight barbed ends and just bend some hose. The space would be enough to bend the hose without kinks I think.
The part I want exists in this kit. I hate to pay $60 for one piece in here

Doesn't work in my case because the turbo sits to close to the block. I tried moving the fitting on the oil pan all the way to the furtherest end of the pan and it still sticks out to far.
Ahhh found exactly what I need for the oil pan

Then I can put in a brass barbed fitting and get my hose on.
Another option would be something like this too

I'd just cut the bolt tabs off the sides and weld it to the pan.

You want to use a turbo drain flange like this:

You can kind of see it in my picture. It'll raise the upper hose end up a couple centimeters and keep the two from hitting each other.
You may also want to measure the angles on your hose ends....they look like 30 deg hose ends (although it's atypical for generics to make a 30 deg hose end).
I also had to use a nylon braid instead of a stainless braid to increase flexibility.

Good luck with it, and make sure you post pictures up of the finished return line so that we can confirm its ok. Oil return line are soooooo over looked at times, its so damn important that the oil just drops back into the sump.

Also you were right, those are 30 degree ends. I got my angle finder out and verified.
Those super compact 45 degree fittings from Earls look like they will help tremendously. I'll have to get a couple and see what I can do.

One of the low profile 1pc fittings and the compact earls fitting should give you enough room but just in case you don't wanna spend another $70 on fittings.
You can buy those weld in bungs on ebay all day long for around $5. It's what I used for my catch can set up I had on my turbo ls. Way cheaper then An fitting and lines but still serves the same purpose. Also can pick them up from Summit or Earls.
