Dorman 42323
Rubber PCV valve mounting grommet with 0.718" / 18.24 mm I.D., 1.403" / 35.64 mm O.D. and 0.638" / 16.21 mm thickness.
Dorman 42323 is a rubber PCV valve mounting grommet with a larger outside diameter than the 42062 version. It seals the crankcase ventilation valve in the valve cover and reduces valve movement.
Application / fitment
Dorman catalog coverage includes selected 1968-1975 Buick, 1968-1991 Chevrolet, 1971-1991 GMC, 1968-1982 Oldsmobile, and 1971-1981 Pontiac applications. Exact fitment depends on engine, PCV valve diameter, and valve-cover opening design.

Compare all three dimensions with the removed grommet. Do not substitute the smaller version because the outside-diameter difference can prevent correct sealing in the valve-cover opening.
