Hard line turbo drain? Issues with passanger axle on hahn kit.
Thursday, April 04, 2013 5:38 PM
So I've installed the hahn kit a while ago, and I'm having this issue with the turbo drain line. It's rubbing on the CV shaft and I've been pondering work-around's for some time now. I've thought up 2 long-term solutions instead of just replacing the rubber line every oil change. 1) Find a pre-bent rubber hose. and 2) use a hard line drain that can be bent and routed with ample clearance.

I figured the 2nd option is the best so has anyone seen this?
What fittings would I need? I can go 45 degree easily, but 37 degree would be tricky, I haven't found a flaring tool for AN flares under $40-50

I believe the fitting is -6AN on the oil pan, but it's a 90 deg fitting.... 1/2"NPT to -6AN the female in the oil pan itself is NPT

I have no idea how hard lines with AN fittings work, but I also found this:

Which would be awesome if it was for a J and not so expensive. Even a universal part like that with just 2 90 degree bends bringing the line over about 6"

Help me

Why not 2 fittings and a stainless braided line?

The braided line would still be rubbing on the CV. It has maybe half an inch clearance if that and driving, turning and bumps definitely makes that clearence 0. I just replaced the rubber drain and after about 2000 miles it looked like it could give out any day. A braided stainless line would just make that every 4k miles instead of 2

does this line dump into the pan?


best solution would be to drill and tap the oil return on the back of the block. it's pretty easy to find, it's a giant 'go nowhere' impression that's on an angle near the middle of the block in the back.

can't miss it.
