I'm in the process of tearing my car apart for a heads/cam upgrade and I can't for the life of me get to the bottom bolt for the #9 cylinder. I've tried an open-ended wrench, long extension through the manifold with both a regular socket and torx socket, and a ratchet with a swivel head. Is the only way to get to this stupid bolt a really long torx head screwdriver through the manifold? Mine aren't long enough and I don't want to go buy a set if I don't need to.
