Hydraulic Lifter
The exhaust hydraulic lifter is attached to the exhaust roller rocker arm with a retaining clip (1). The internal check ball is reversed, compared to previous model years.
NOTE:
The exhaust hydraulic lifter and exhaust rocker arm should not be unclipped during diagnosis and handling.
NOTE:
The exhaust hydraulic lifter must never be interchanged with any other hydraulic lifter than what is specifically designated for this vehicle. The internal check ball is reversed and could cause engine damage if an incorrect part is installed.
The intake hydraulic lifter has a dual feed feature (1) to accommodate the two-step Variable Valve Lift (VVL) system.
