Description of Change: The new O-rings are made with a material that is better able to withstand high temperatures. The new O-rings retain elasticity and provide a longer service life.Adaptable To: Use the new 214-7566 O-Ring Seal in place of the original 3J-7354 O-Ring Seal, which is not canceled.If a 3J-7354 O-Ring Seal is found to be brittle, install a 214-7566 O-Ring Seal .Also use the 214-7566 O-Ring Seal when a cylinder head is overhauled or when the engine is overhauled.Locations of the plugs and the O-ring seals in the cylinder heads are shown in Illustrations 1 and 2. Effectivity is listed in Table 1.
