Stubborn oil leak from turbo drain flange

Not really sure where else I could have posted but just looking for advice.

I got a 96 Ranger Splash with a 2.3T motor from an old TBird turbocoupe. I have a problem getting anything to seal the drain flange to the turbo housing.

The oil supply has a boss that is threaded and works with no leaks under pressure. It has me wondering if the drain hole could be tapped and threaded for a barb fitting?
This isn't something I intend to attempt, I'm beyond frustrated. I would seek out someone to do that task for me.

I think a pic would help determine a solution

This isn't my setup as my turbo is still mounted but it's very similar. I have the two bolt style flange and it's just not sealing for me.

My thoughts were to tap that center hole and thread in a barbed pipe fitting that I can press a hose on to.

For those flanges I always steel wool both surfaces. Then brake cleaner them and blow with air. Use a cork gasket and spray Permatex Copper Spray a Gasket on both sides of gasket. Then install. Never leaks.

I have broken the factory drain hose and working with an aftermarket flange. I have tried a few flanges for AN fittings but haven't found one that works without grinding away on it. So I'm stuck with another aftermarket flange attempt, or a used factory line that I'll likely bust. I thought if that holes was tapped by someone that knew what they were doing, a brass barbed fitting from Home Depot would take care of the issue.

I have found that the flanges will warp, end up taking off to square it back up and reinstall, you can check it with a straight edge. As for tapping the hole if the turbo has been on it for a while its been heat treated, be careful and go slow it will be hard to cut.
