What it does
Worn rocker tips or pivots cause noise and poor valve control. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Check rocker geometry and adjust valve lash or preload after installation.
- Pushrods: Rocker changes can change the pushrod length you need.
- Valve cover gasket: The cover comes off for this job.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
