ok i think im in trouble!! i was told in another forum that i had to take my valve cover off!! i took it off, i noticed i coulnt get to the round thing called a cam end seal!! so i proceed to take off the 12 or so bolts that hold a "rail" thats right on top of the cam!! so i take it off, scratching my knuckles because there so tight, and i see that i still cant get to it so i put that rail back on and when i was tightenning the last two bolts (which are the only 10mm bolts there) i broke one off!! now im like WTF!! is that a real bad bad thing?? or is it just a bad thing that does no harm?? some one plz help me!!
