## Discrepancy

THE ENGINE HAD A CYLINDER ISSUE, THE MECHANIC CHECKED THE ENGINE FOR METAL IN THE OIL FILTER. THE FILTER HAD METAL IN IT, THE ENGINE WAS SENT TO OUR FACILITY FOR A TEARDOWN INSP. UPON THE TEARDOWN INSP OUR FINDINGS WERE THAT: 4 LIFTERS WERE BADLY SPALLED WHICH CREATED A METAL CONTAMINATION.
