I talked to the tech about the special tool. He said that the tool is used to remove the upper guides without breaking them and, most of the time, they are so brittle that they break anyway. In fact, he advised me to shove some rags under where the timing chain goes down into the engine so none of the plastic will break off as you remove the old guides. No special tools are required unless you're trying to get them off without breaking the guides. There are only 2 Allen bolts on each side that hold the guides on.
