Hi, I did a valve adjustment on my 98 2.5 DOHC using flat screwdrivers, tweezers, and magnetic pick up. It is extremely tedious to do it that way but can be done. If you have taken all of your clearances and are ready to get the shims out of the cam followers, it can be done using flat screw drivers on the edge of the buckets, but the tool would make it a breeze. I gave up on the high cost of the tool and also thought of begging someone to loan me one........good luck.............
