## Discrepancy

ALL VALVE COVERS FOUND LEAKING.  REMOVED ALL VALVE COVERS AND FOUND THE UPPER SECTION OF THE VALVE COVER GASKET NEAR THE EXHAUST VALVE HAD SHRUNK, PULLING IN TOWARD EXHAUST VALVE SPRING.  WE HAVE FOUND THIS ISSUE ON NUMEROUS ENGINES WITH THE SUPERIOR VALVE COVER GASKETS MENTIONED, PN SA534857.
