The torque value stated is very important to accurate timing. Always use the correct
value of 0.6 Nm, as set using T3880609 - Timing Torque Limiter. Using an incorrect
torque value will result in incorrect valve timing being set, or damage to the tensioner
blade or other valve train components. Either condition may result in serious damage
to the engine, reduced engine performance, or reduced fuel economy.
