Improper repair procedures during engine overhaul can cause failure of the cylinder head gasket and/or spacer plate gasket. Improper repair procedures cause loss of load on the cylinder head and related components. Insufficient load can result in head gasket failure, liner flange cracks, and spacer plate gasket oil leaks.

The illustrations that follow are examples of frequently seen failures due to improper procedures. Instances where improper procedures are used are not a material deficiency problem.

Illustration 1	g03832686

Illustration 1 shows examples of material removal from the spacer plate gasket. This failure is caused by gasket movement and/or loss of load from improper installation.

Illustration 2	g03832846

Illustration 2 shows examples of bead and outer dust seal separation. This failure is caused by gasket movement and/or loss of load from improper installation.

Illustration 3	g03832900

Illustration 3 shows examples of compression ring failure. This failure is caused by gasket movement and/or loss of load from improper installation.

Illustration 4	g03832916

Illustration 4 shows examples of a spacer plate cleaned with a wire wheel. Wire wheel use can cause an uneven contact surface during installation between the spacer plate and gasket leading to gasket failure.

Refer to the publications below during overhaul and installation of the cylinder head for the correct procedures to be used.
