General
When following the torque sequences below, wait approximately 15 minutes between torque steps to allow the studs to stretch and fully settle before the next torque application.
Note: The 16V tightening sequence differs slightly from the 8V sequence. Refer to the 16V Cylinder Head and Head Gasket Removal and Installation procedure for the correct 16V sequence.
