Ok well i had a friend of mine today to adjust my valves. And we are taking out the bolts for the valve cover, and we got most of them out but 2 didn't want to come out, they just spun, he said that the stud is moving with it when we try to loosen it. I tried to use a impact gun i found in my garage but it is a sucky one, it like gives up when i try to take out that nut it just doesn't move. So i wanted to know if there is any other way to take it out. I am going to get a new impact gun but in the mean time i want to try other stuff. I have a 99 ls motor if that makes a difference.

 

ok well i got a good impact gun, and it still turns. I did it by bursts also. The nut keeps on spinning and i see like metal dust around the nut i think it is stripped. How will i get it out

 

post pics/vids? that might help. try "motivating" them to un screw by using a flat head screw driver and prying up on them while unscrewing them

 

thats what i've always done when i had a stubborn valve cover nut. works everytime.

 

bolts like for a vtec head or the nuts for a non vtec head? you u mean the studs for a non vtec head?

 

yea i have a ls, i am going to try to pry it up and unscrew to. Thanks
