I have a plumbing question for yall

Got a bathroom sink that takes 10 hours to drain.
Originally thought it was the stopper broken off causing a block. Changed all that.
Then I figured maybe there was a blockage in the main vent line.
Shoved a water hose in it and ran it for 30 minutes. Sink still wouldn't drain. Dumped a bottle of draino in it. Still wouldn't drain.
Used a 15ft auger on it, hit NOTHING in 15 ft.
Used a plunger on it blocking the over flow with my thumb. Plunger forces the water under it down the drain, nd then creates an EXTREME vacuum.
So hard I can barely pull it up with one hand.
Sink still won't drain.
All other drains in the house work perfectly. Hell they work better than ever since I ran the hose through the vents.
Can the OB offer any suggestions here? :

that is a damn tough one. if there is no gurgling or backing up anywhere else, I would have to suspect that it is somewhere between the sink stopper and where that leg ties into a mainline. not sure to tell you how to figure that out, though. let me think on it a bit.

I would start by disassembling all the drain pipes under the sink and inspecting everything

I would go back to the vent pipe. Those things can be a bear. Are you using just a water hose or a hose with a pig on it?

If you push your plunger down and you can't pull it back up that means your clog is before the vent in that pipe or your vent is clogged and your have another clog past the vent. You should have a branch vent right at the drain going into the wall. When your pipe goes into the wall it hits a T, wet goes down vent goes up. Flushing your main vent isn't going to get that.
The horizontal portion of your branch vent should be several inches above the top of your sink (Can't remember the number off the top of my head). If your branch vent is below the top of your sink your branch vent can clog and you essentially have an unvented drain.
I'd pull the pipes out and see if you can get your auger turned up into the branch vent and see if you can find a clog in the vent.

Remove the p trap and drain pipe into the wall. Then use a Drain king. Shove it as far into and own the pipe in the wall as you can. Check your tub drain for sound of water flowing by. Might want someone to verify no water comes out of any vents as well. Might want a bucket in the event some water leaks out before it can seal around the pipe.

EXTREME vacuum.
Hopefully "extreme" is a little hyperbole.
The blockage is either before your vent or your vent is clogged as well as the drain line or you don't have a vent for that sink.
The odds of both vent and drain being blocked is minuscule. If its a older house that has had some remodel done it wouldn't surprise me to find that sink doesn't have a vent.

Sounds like a major clog in the drain line before the vent. If it was just a clogged vent, then the sink would drain but suck the trap dry. Since there is a vacuum when plunging, the vent cannot communicate with the sink - it it could, there would be no vacuum. Try fishing into the drain pipe with trap removed.
