Disassembly sequence
CAUTION
• The rocker case and the camshaft caps have been machined together, which means that they all must be
replaced together. The removed camshaft caps must be identified by attaching tags with their cylinder
numbers because they must be reinstalled to their original positions on the rocker case.
• Do not remove the Powertard solenoid valve unless necessary for replacement.
Assembly sequence
Follow the disassembly sequence in reverse.
