All Torana (LJ-LX) / GTR / SLR / A9X problems All workshop issues
Common Engine, Holden V8 (253ci / 308ci)

Valve Train Noise (308 V8)

Symptoms

Ticking or clattering from the top of the engine. May vary with RPM.

Cause

The 308's shaft-mounted rocker arms wear at the tips and the shaft develops scoring. The pushrod tips can also cup. This is accelerated by infrequent valve adjustments and oil that's too thin.

Fix

Inspect and replace worn components. A Yella Terra roller rocker conversion ($400-800) is the definitive fix, it eliminates the wear mechanism entirely and frees up a small amount of power by reducing friction.

Cost mentioned in fix
$400-800
