Spotting valve train wear
Rocker arm pivots carry the load of the rocker arms every time a valve opens, so wear at the pivot shows up as valve noise, uneven valve timing or a rocker that moves sideways on its stud. Worn pivots can also enlarge the rocker bore, which is why inspecting the arms and studs at the same time is a good habit.
Clean, lightly oiled pivots move freely and hold their position. Keep the valve cover clear of debris during assembly, and recheck the valve lash after the first few warm-up cycles, since settling can change how the rockers sit.
- Ticking from the valve cover area
- Rocker arms that rock side to side
- Uneven valve lash after assembly
- Worn studs or rocker bores

Installation notes
Pivot fit depends on the stud or shaft and the rocker arm design on your engine, so confirm those details before installing. Valve train work needs clean parts and careful assembly to the engine rebuild requirements.
What’s included
Rocker arm pivots only. Check the quantity against your rocker arm count before starting work.
Not included: rocker arms, studs, push rods and other valve train parts.
