240sx valve cover problems

[MrKanin]

some bolts wont come out, and now some wont go in.....
lol whats the deal?
i bought a new seal and was going to install it today abut like i said the some bolts wont come out, they just keep spinning.

and ideas?

[MrKanin]

scuse me, its the bolt for the valve cover.

take the ones that will come off, off, and see if the valve cover will come off, something tells me you have a few stripped ones. Its really easy to strip them, the stud i mean, not the cap nut, the stud will strip in the head, because the head is wimpy aluminum.

[MrKanin]

so wont i not be able to put any bolt back on after i strip the aluminum?

you have to tap them out. ive done this once before =.=

(tap the screw and reverse the thing out with an oppositely threaded drill bit.....)

but it depends on how it's stripped really...
