In the first two pictures, there is a brown thing that holds the timing chain in line. I can't get, or don't know how to get the bolt out. I think i need to

In the third picture, I have taken the camshaft bolt out and tied welding wire to keep it timed, do I just take the sprocket off from there?


The head bolts are 8mm 12 point, but i only can find 8mm 6 point Where might I find this part?

On the IP delivery valves: I bought 4 new o-rings, but some one said I need some copper washers along with that, Is that true?

Well thanks for everyones help I just want to be sure i do every semi right, I don't want to tell my mom (i no it sounds lame) that my car wont be leaving the garage, be cause its broken

Also I just figured out something is wrong with my generation(not all of them, probably my area): Laziness.
car break, dad's there to fix it. Stupid video games
