What was found
DURING ANNUAL INSPECTION, FOUND LT BAFFLE TIE ROD, PN 4197500, HAD RUBBED A HOLE IN BOTH INTAKE AND EXHAUST PUSH ROD TUBES ON NR 4 CYLINDER. THE ROUTING OF THE TIE RODS ARE VERY CLOSE TO THE PUSH ROD TUBES. SUBMITTER SUGGESTS THAT ALL BAFFLE TIE RODS BE LOOKED AT CAREFULLY FOR PROPER ROUTING DURING SCHEDULED MAINTENANCE OR WHEN LOOKING FOR OIL LEAKS. THIS COULD CAUSE A LARGE LOSS OF ENGINE OIL.
