2-3B 3 Camshaft removal pg 35 gives 2 different torques for the camshaft bolts. T2(7.2ft/lb) for the 2 on the front end of the engine, and T3(14.5ft/lb) for the 4 in the center and rear.
this is for the ej25 engine.
the front two bolts are different.
DO NOT over torque.
you will regret it.
i assume the other is for the ej22, but i don't really know.
i do know that the design is different.
the ej22 cam shaft rides in the head.
the ej25 shaft rides in a channel created half by the head, and half by the caps.
