Crankcase Depression Regulator Valve or CDR Valve for 6.2 Diesels 83-92. This valve is similar in function to a PCV valve in a gas engine. On a diesel, the CDR valve regulates the amount of pressure or blowby from the crankcase back to the intake thru the turbo. This is a maintenance item and should be replaced every 30K miles as recommended. 6.2/6.5 diesels need to run a slight vacuum in the crankcase and this valve regulates that. Includes new rubber grommets and sleeves to mount.
