On-Vehicle Inspection

G12586937Courtesy of SUBARU OF AMERICA, INC.
  1. Visual check of hose, connection and gasket
    1. Check the hoses for cracks, leakage or damage.
      NOTE:
      • Removing the oil level gauge, oil filler cap, ventilation hose, etc. causes an engine trouble or engine stall.
      • If any of the parts between the throttle body and cylinder head are not installed, loose or cracked, the engine intakes secondary air and this causes an engine trouble or engine stall.
