BULLETIN NO. PCE-020 DATE 10/81 CHRYSLER 225 SLANT SIX-SPARK KNOCK > j CHRYSLER 225 SLANT SIX-SPARK KNOCK ' Chrysler Corporation advises that some 1978-80 vehicles with the 225 slant six have spark knock problems. Originally, these engines had beaded steel head gaskets .015" thick. Replacing j the steel gasket with our Victocor gasket, # 1162-VC can help. Our Victocor gasket is .045" thick .036" compressed so it will lower the compression ratio slightly, | eliminating most cases of spark knock. Of course, the mechanic should check timing and carburetor adjustment to be sure they are within specifications. i I ! I i
