    Default I do have a crack in my firewall!

    Dogcharmer pointed this out in my t5 swap thread, but I thought it was just a shadow or somthing. Well yesterday when I was cleaning up a bit, I got to looking at this and shure as shit I have a crack! I've never heard of anyone with this problem yet. My car isn't rusted underneith or anywhere . Just a six inch long crack that starts under the throttle cable and goes towards the tranny tunnel.

    Maybe it's my monitor, but it's so dark I can't see it.
    Here's a much-brightened version.
    Strange stuff indeed.

    Cut it out you two doo-doo heads...


    Aside from welding it there isn't much you can do aside from perhaps drilling a small hole at each end of the crack to stop it's propagation. Either is going to be difficult with the engine in the car though...and welding might be risky in that the inside of the car may catch fire depending on what's there. A steady succession of spot welds might work and keep the overall heat down if you do it slow enough.
    It may be a good time to consider some chassis bracing. The car may not be a powerhouse, but just general usage can cause cyclic failure issues....

    A dremel with the flex attachment and a carbide tool might be able to put some holes at the end of the crack to end its path of destruction.

    If you plan on never having it welded...some JB weld or appropriate epoxy would probably fix it too (after you drill the end holes).

    True, that would work too

    Like the others said- you need to stop-drill the crack before it gets any longer. Do you have any idea what's going on behind the firewall? Any stuff missing/out of place?
