## Discrepancy

ENGINE WAS JUST RECENTLY OVERHAULED BY AN EASTROM DEALER IN SPRINGFIELD, MO.  ON THE FIRST 50-HOUR INSPECTION, THE VERNATHERM VALVE, PN 75944, WAS REMOVED FOR INSPECTION TO COMPLY WITH LYC SB518C.  THE VALVE HAD A LOOSE CRIMP NUT AND VALVE CONE HAD WORN GROOVE.  IT IS VERY LIKELY THIS WAS NOT REPLACED AT MAJOR OVERHAUL AND WAS THE ORIGINAL WITH 3391.5 HRS. RECOMMEND THAT SB518 BE AN AD SO PEOPLE COMPLY WITH IT.
