STACKED SEALS RESULT FROM FAILURE OF THE SERVICE TECHNICIAN TO REMOVE THE OLD SEAL PRIOR TO INSTALLING THE NEW FILTER AND SEAL.DISTORTED OR PINCHED SEALS RESULT FROM FAILURE TO PROPERLY LUBRICATE THE NEW SEAL PRIOR TO INSTALLATION. OIL LEAKAGE FROM A STACKED, DISTORTED, OR PINCHED SEAL CAN BE IGNITED BY HEAT FROM THE EXHAUST SYSTEM, WHICH IS LOCATED NEAR THE OIL FILTER IN THE SUBJECT VEHICLES.HONDA WILL ISSUE COMMUNICATIONS TO ITS DEALERS WARNING OF THE NECESSITY TO FOLLOW CORRECT PROCEDURES WHEN REPLACING OIL FILTERS IN THE SUBJECT VEHICLES AND OF THE POTENTIAL FOR VEHICLE FIRES TO RESULT FROM IMPROPER REPAIRS.ODI WILL CONTINUE TO MONITOR THE ALLEGED DEFECT IN MY 2003 AND LATER CR-V VEHICLES.THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.
