## Discrepancy

(CAN) DURING INSPECTION, IT WAS NOTED THAT THE INTAKE GUIDES WERE LEAKING OIL.THE SPRINGS WERE REMOVED TO MEASURE THE GUIDE HEIGHTS.THERE ARE NOW SHORTER GUIDES THAT REQUIRE THE INSTALLATION OF A SEAL.  SOME OF THESE SEALS WERE NOT INSTALLED ON A BATCH OF CYLINDERS.WE WERE GOING TO MEASURE THE GUIDE HEIGHTS TO SEE IF THE SEALS WERE MISSING.IT WAS AT THIS TIME IT WAS NOTED THAT THE GUIDE ON NR 6 CYLINDER WAS LOOSE.
