Welcome to the site....I would just sell it...I've come to the realization that I have to get rid of my car before the year is out. Not due to mechanical problems like yours but just because it isn't big enough. The reason I say that is because at some point you have to say enough is enough, and either suck it up and put decent money into it to fix all the gremlins or just scrap it and get something a little more headache free.
Good Luck in your decision!
My two cents is to sell it if you don't have the cash to fix everything.
