Callout	Component Name
1	Positive Crankcase Ventilation Tube with Positive Crankcase Ventilation Valve - Foul Air NOTE: These components have tamper-proof connections and cannot be disassembled. Remove this component only if inspection indicates replacement is necessary. Procedure Inspect all positive crankcase ventilation (PCV) components prior to removal. Do not remove the PCV components unless a diagnostic or inspection procedure indicates replacement is necessary. Complete all camshaft cover inspections prior to inspecting or removing PCV components. If inspection indicates the camshaft cover requires replacement, all PCV components will be replaced with the cover. Remove the PCV valve from the cover by twisting and breaking the connection. Retrieve any particles that fall onto the baffle in the cover. Discard the valve and particles.
2	Positive Crankcase Ventilation Valve Bolt [2x] NOTE: Bolts are tamper-proof. Remove the bolts only if inspection of the PCV tube or valves indicates replacement is necessary. Procedure Using a suitable tool, cut a slot in the tamper-proof PCV bolt heads and remove with a flat-bladed tool. Discard the bolts.
3	Positive Crankcase Ventilation Tube with Positive Crankcase Ventilation Valve - Fresh Air NOTE: These components have tamper-proof connections and cannot be disassembled. Remove this component only if inspection indicates replacement is necessary. The PCV tube to fresh air inlet duct connection is tamper-proof, and the inlet duct must be replaced when servicing PCV valve components. Procedure Inspect all PCV components and the fresh air inlet duct prior to removal. Do not remove the PCV components or inlet duct unless a diagnostic or inspection procedure indicates replacement is necessary. Complete all camshaft cover inspections prior to inspecting or removing PCV components. If inspection indicates the camshaft cover requires replacement, all PCV components and inlet duct will be replaced with the cover.
