4AFE Engine Block and Head Surfaces

    After removing the head, I jump to inspect the cylinder head gasket, engine block mating surface, and the cylinder head.

4AFE Cylinder Head Removal

BACKGROUND:                 In this article I will describe the procedure for a head gasket replacement I did to a friend's 94 Toyota Corolla DX. He contacted me about oil appearing in the coolant when he inspected his deposit and radiator level; I refer to this as "oil to coolant mix." This is an indication of head gasket failure.
