For parts service, the 7W-2059 Cylinder Head Gasket may be used in all 3204 or 3208 engines. The 7C-1599 Cylinder Head Gasket may only be used in 3208 engines with standard cylinder bores that have never been repaired with a cylinder sleeve. As shown above, the 7C-1599 Cylinder Head Gasket has a smaller inside diameter. Use of this gasket in engines that have had cylinder sleeves installed may lead to gasket failure due to the fire ring overlapping the flange of the cylinder sleeve.
