Some Serious neck issues

I use a Fender Modern Player Jaguar, it is asian made but very well made as far as asian made basses go. It never wants to stay setup. The truss rod is also very difficult to turn when I need it to. Any tips on how to tackle this problem?
 
in what way does your bass not stay set up - is the problem with the action, neck relief, neck angle or ???
The action just gets worse every day. I set it up like my other bass which is way more of a cheaper build but it has the peavey truss rod access so I've never had a problem with it. anyways One day I can get the action set up as much as i can and then the next day it will be back to buzzing

I was gonna guess a problem with the truss rod. It sounds like when he adjusts it to add some relief, the adjustment isn't holding and the rod and neck are just returning to their previous position. Plus, he said that it is "very difficult to turn."
 
Well of he's adding relief that means he is loosening the rod. If it's difficult to turn when loosening, there is definitely a problem to be looked at.
If warping, that's another matter.

Let's see if there's warranty first. If so, get it to a fender dealer for assessment.
 
Update I tried to get a picture as best as possible but I found that the part of the hex key on the truss rod is worn. Any tips on replacing it and where to get a new one?

This bass has a long history with neck issues already. It started with a weird nose coming from somewhere on the headstock. I gave it to a guitar tech at a local store and he absolutely botched it. He busted the wood around the nut and put it back with super glue. It didn't fix it. I brought it to another guy. He did the SAME THING and now its even worse and he robbed me out of my money. Then I gave it to one last guy who saw the poor jaguar and figured out the problems over weeks of trouble shooting and he only did it for $20 just to make the sound go away. But this thing is just gooched sometimes
 
If I understand you correctly, you keep raising the action, and then it goes back to buzzing? Is the buzzing happening around the low end of the neck (3rd-6th frets) or way up at the high end (15th to 19th)?

If the buzzing is happening at the low end, that indicates that the neck is backbowing. That is, it's slowly warping, bending backwards.

If the buzzing is up at the high end, that means that it's developing a "ski jump". That's a different condition, where the neck is bending forward around the 12th fret.

In either case, the truss rod can't fix either of those conditions. That's a single acting truss rod. It can't push the neck forward. The most you can do to correct backbow is to loosen it all the way.

So, that's the first thing: Turn the truss rod nut counterclockwise to make sure it's fully loose. Then see what the neck looks like. Is it backbowed, flat, or does it have a little bit of relief?
 
That's a disastrous mess! Best I can offer is to suggest you find a proper tech - perhaps someone who actually builds basses - and have them size up the problem. The nut is ruined and the wood repair to the headstock is terrible. And even if the trussrod is not holding the neck in proper relief, there's a good chance that can be fixed.

Bruce is offering good advice. All I would add is that you don't judge the results of your efforts on how the open string behaves, only fretted notes (the nut is wrecked and open string notes will not behave).

The problem is is when it needs adjusted I adjust it (as much as I can with my stubborn truss rod either relieving or adding tension and then once I get it done and sounds all good just a day or so later its back to buzzing. I called the dealership and he said I would have to bring it in
 
THIS IS GOING TO SOUND REALLY STUPID: I just found the reason why it's been having a hard time turning. There was a peice of something (didn't seem like the wood) stuck in the hexagonal key. Wow. I relieved it a bit and now it plays better than ever

Probably dried up super glue, that poor bass is a mess.
