Stripped timing cover

If you stripped the top left or top right hole you stripped the block, not the timing cover. Only the top middle hole goes into the timing cover. I stripped the top left hole in the block once and had to pull the t cover back off and heli-coil it. A lot of the time the reason threads strip out is because the bolt isn't long enough to engage enough threads. Always make sure the bolts are long enough, but not so long they bottom out either
