Valve Train Analysis - Engine Running

NOTE:
  • Static checks (engine off) are to be made on the engine prior to the dynamic analysis.

    Prior to performing any dynamic checks, make sure the transmission is in P (Park) (A/T) or N (Neutral) (M/T) and the parking brake is fully engaged.

Start and idle the engine. Check for proper operation of all parts.

  1. Check for plugged oil gallery in the rocker arms or cylinder head.
  2. Check for proper valve train lubrication.
