alright first i noticed that my valve cover nut was a little loose so i tried to tighten it and wabam it was stipped so i thought no big deal ill just buy a new nut. ok so i bought the nuts and it seemed to fit a little funny and when i was tightening it it stripped out the dam stud. now i need my car daily so im workin on gettin a valve cover gasket and that good stuff for when i have to take it off to do the repair. ive never worked on the anything past the intake manifold or wiring so i have no idea what to expect. like if you can just take out the stud and put in a new one or what. can anyone give me any suggestions on what i should be expecting or maybe even step by step what i should do? anything should help.

thanks
travis
