well i took off my valve cover today. when i tried to put it back in, i noticed that 2 of the 11 bolts weren't threading back in. i took off the bolts and the valve cover to discover that my threads on the bolt holes were stripped. is there anything i could do? i tried to test whether or not the bolts would go in and all they did was drop in and out, eliminating the possibility of tapping the holes.
the ones in red are the two that aren't threading back in.
