need help putting in a cam gear in does it have to be done a certain way?

 

its a pain in the *** if you don't know what you are doing. goto your haynes manual and look up timing belt change. same as that except remove the cam gears, and install the new ones. make sure to torque the cam gear bolts down.
pretty much loosen the tensioner bolt, pull the valve cover, pull the tbelt off the cam gears, change the gears, and put the belt back on(make sure timing is correct with the crank pulley)
