    Angry Snapped the valve cover screw off in the head...BUMMER!!!!

    Torqued down to hard on the lower left valve cover screw on my 2007 RT. Does anybody know the fix? And can I ride it anyway? It doesn't seem to be leaking. Oh and by the way I know it was stupid and I'm already feeling ( stupid I mean). Any advice would be appreciated. Thanks.

    Easy fix, many of us have been there with that screw......or other ones Heli-coil and a few others all work. Do a Google or tube search and I'm sure you will find a good "how to" vid.

    If you do it and it is your first time, practice once on an old fitting of some sort.

    As for riding it now, well, I would get it fixed sooner, rather than later. However, if it is not leaking, well, kinda your call.

    I would start with an exact center punch, then a left handed drill bit. It should come out.

    Then I would be using a torque wrench.

    Good luck

    Are you sure you snapped it off? Usually the threads in the head strip; I guess that is what I thought you did.

    If it is snapped, your fix is even easer, however, I would not ride it until it is fixed in that case. If it is broken off flush to the head inside, or close to it that could mean a couple inches of cover screw will be wiggling around near moving parts! Also, with the engine vibration I doubt the screw will stay put with just the rubber collar holding it in place.

    If the head broke off outside the cover......Your life is very easy. I still would not ride it.

    I guess I will ask again, are you sure it snapped and did not strip it? I have never really seen that screw snap. If it did snap, where did it snap?

    Three ways cap screws break:
    1. Bottomed in the hole. Really bad, lots of force holding it from turning.
    2. Rusted in. Heat, solvents and nut trick below are apt to work.
    3. Over-torqued but not bottomed. The easiest, should be loose. Use an ice pick and hammer to apply torque to back it out.

    The slickest broken bolt removal I've seen:
    If the broken end is flush with the surface a welder can position a hex nut about centered on it and with a wire feed weld the nut on. Not only provides something to get hold of but the heat helps loosen. For that one guy who will want to rain on my parade - yes the welded bolt is junk and it's too short anyway so you throw it away and get a new one.

    I do a lot of these. Here is the first example I could find.

    Nut welded to stud in a blind hole.

    With the screws in question, this doesn't happen, as they're designed to bottom. This prevents you from flattening the gasket to uselessness.

    This is a clue.

    If you really really can't afford a torque wrench, just stop when the screw bottoms.
