## NHTSA's summary

ROCKER ARM ASSY \- ROLLER ROCKER Case 1.\- Before replacing the intake or exhaust rocker arms due to an abnormal ticking noise, please check that the INTAKE Hydraulic Lash Adjusters are not "collapsed". If a collapsed INTAKE HLA is found, replace all INTAKE HLAs on the suspect cylinder head \(no need to replace rocker arms\). The noise can occur at low or high RPMs, and at low or high temperatures. There are no Diagnostic Trouble Codes \(DTC\)s present. Case 2.\- If the INTAKE camshaft or INTAKE rocker arm has excessive wear on the high lift profile \(Rocker arm: slider, Camshaft: central lobe\), replace the intake camshaft \(1\) in that cylinder head and all intake rocker arms \(6\).
