Thin stamped timing covers distort when the bolts are pulled down, which is how the front seal ends up leaking on an otherwise fresh engine. The welded reinforcement here stiffens the seal area so it stays round and the crank seal sits square. Chrome plated for a finished engine bay rather than a bare stamping.
