Default Turbo drain obstruction

Morning all. Anyone run into an issue like this? The drain fitting/line is going to be obstructed by the bolt for the compressor housing. Im running the Huron Speed single turbo kit. Not sure what to do here. Any input? Thank you

Remove the offending bolt on the compressor housing.
5/6 bolts is fine, the housing seals with an o-ring.

Look into diesel turbo drains. They won't be AN fittings, though.

Do you have a link?

i just don’t understand why this is a problem? I’m sure turbonetics is well aware that once the oil goes into their turbo it doesn’t stay there forever? Obviously there needs to be a drain on there. Why is it obstructed? Is it just my turbo? I’ve never heard or read anyone having a problem like this. I really really hope I’m doing something wrong or overlooking something but I don’t think so.

That doesn't look like that will clear even if you removed the bolt.
Contact Jon at Huron Speed and show him the pictures, maybe the wrong drain flange got packaged.
Jon is a great guy and will help you however he can, with that being said JoeNova is right.
There's a 3/4" flexible metal oil drain that will work better than AN lines will.

Jon and Huron speed have the best customer service I’ve ever encountered. The guy emails me back every time super quick. He mentioned something about clocking the turbo. I talked to my buddy who knows about turbos and he said the bolts can be loosened and the housing can be rotated around (clocking) until the drain clears. Just as I hoped it was something I overlooked. Too bad I just ordered some adapters and fittings I’ll try when I get home and report back

I'm also using the Huron Speed kit with a 7875 turbo and my drain looks identical.
I also ended up clocking the compressor to get clearance and its worked fine for years, your photo may have been a little deceiving as it looked really close to the compressor housing.
Just make sure the drain is straight down and you have adequate crank case ventilation, that drain won't have much angle to it and poor crank case ventilation could cause poor draining and oil backing up in the turbo.

Just make a drain with a bit of pipe to clear it, and it'll easily have a larger ID than those AN fittings anyway, all of which is good.

Clocking the housing is a simple matter. Don't send back any adapters and fittings you have, though. You can never have too many laying around. Good luck with your build.
