    I'm trying to remove the front exhaust manifold. I'm not getting the nut on the left just below the coil pack to turn at all. I'm convinced its a 13mm nut, my sockets or wrenches will not go on, I think its the heat shield not allowing me to get a good hold of the nut

    same thing happened to me... just have to keep maneuvering the socket head until it goes on enough to turn it. The heat shield can get in the way just like you said.. Just have to go slow and eventually it will come off. Try putting some WD40 on it to soak the nut/thread a bit to help with the removal

    still ticks with either gasket, the bolts are tight, I have snapped some in the past so I know when to stop tightening them, not sure what else to do

    can you pin-point where the leak/tick is coming from? closer to the flange connecting to the head? maybe the crossover connection?

    I personally don't see why not.. But I am still surprised there is a tick.. Even with putting a layer of epoxy down, you still may end up having a path form for the exhaust to squeeze out of.

    If it were me, I would avoid the gasket-form and try a few more things first just in case

    spray some carb cleaner or WD around the manifold flange and fire it up to see if you can see bubbles forming in a certain spot to pin-point the leak. That'd be the next thing I would do. How bad is the ticking sound? noticeable from inside the car?

    the ticking sound happens only when I step on the gas to accerlate, its fine at idle or crusing speed
