valve cover bolts

while trying to change my valve cover gasket i stripped the last bolt, so there's only one bolt left on it. is there anyway i can get is off, it seems to be stripped in two of the eight corners of the bolt, or can i use some sort of sealant to keep my cover from leaking? thanks you guys

Permatex gasket maker ($4.99 at Advanced Auto for a tube), or drill the hole and tap it, but gasket maker would be easier.

i would say drill and tap it but you can replace the bolt with any ordinatar bolt it doesn't have to be the $8 bolt from a dealer. I snaped one of those in half and had to get it out with a screw driver and a hammer it took at least an hour and i put a normal bolt in it and it hasn't leak any oil or anything.

Wait, did you strip out the threads or did you round off the bolt head?

stripped in two of the eight corners of the bolt,

I think the bolt is just jacked so he can't get it out, did you try vice grips? Also aren't there only 6 sides on the head of any bolt, hense the 6 point and the 12 bolt sockets?

Go to Wal-mart, they carry sockets for removing bolts with "stripped" heads. Just hammer it right on, and it works by the same principle as a screw extractor.

Next time 6pt. bolt = 6pt. socket.

Next time 6pt. bolt = 6pt. socket.

Thanks for clearing that up lol

gator grip. I use mine all the time for most bolts.
