## Discrepancy

DURING A SCHEDULED MAINTENANCE INSPECTION OF THE ENGINE ROCKER BOX COVERS, EVIDENCE OF OIL SEEPING FROM CYLINDER #4 ROCKER BOX COVER AREA WAS DISCOVERED ON RAISED "LYCOMING" STAMPED. FURTHER INSPECTION WITH A 10X MAGNIFYING GLASS CONFIRMED THE STAMPED AREA TO HAVE SMALL HOLES/CRACKS DIRECTLY AROUND THE EDGES OF THE STAMPED LETTERING.
