hi i am in the middle of replacing coilpacks on my motor, all the tutorials i've seen however show a different type of manifold (mine have round pipes) and im stuck ... i hve 6 bolts taken out but something is holding manifold at the top-right corner, i can feel the bracket at the back but im not sure if i can get to the bolt (extremely tight)  could someone tell me if this is the bolt i should attack or is it something else holding it ?   [uPDATE] Had to throw in the towel, there is no chance for me to stick my troll hands into that tiny gap, there is a 3/4" wiring loom obscuring the access also, i will try next weekend when i acquire longer ratchet extension...   i have replaced the front coil packs, 1 was different then all the rest, and two had split rubber seal on the tip...
