17628-ZV0-000 Honda LINK, FUEL CAP (Honda Code 1814805).

Introduction
The updated Open Crankcase Ventilation system (OCV) reduces oil emulsions during low load conditions at moderate ambient temperatures. The updated (OCV) system increases the temperature of the gases that enter the filter of the (OCV) system. This is accomplished by replacing the aluminum parts of the breather with nonmetallic parts and by insulating the hose from the breather to the canister. The updated (OCV) system contains a revised canister that separates the condensed water from the oil. Only the oil returns back to the engine. The new installed hardware prevents premature tripping of the pressure sensor that measures the pressure of the crankcase ventilation. Some oil emulsion on the oil fill neck is acceptable. Oil emulsion may be present on the inner top surfaces of the valve cover in low load, moderately cool weather conditions. Some oil emulsion is acceptable.Note: The new (OCV) systems are adaptable back to the first production of the listed machines. The change is effective at the factory with the engine serial numbers S/N:LEE22319-UP and ; S/N:SDP22046-UP.C13 Front Mounted Open Crankcase Ventilation System for Kenworth and Peterbuilt Trucks
