NHTSA Complaint #10715355 — 2004 HONDA PILOT

HELLO. AFTER SMELLING GASOLINE TYPE FUMES OFF FOR SOME TIME (NO ONE ELSE IN THE FAMILY COULD SMELL IT) AND AFTER CONSULTING THE HONDA PILOT FORUMS, I DECIDED TO REPLACE THE FACTORY NGK PZFR5F-11 SPARK PLUGS AT 99,430, RATHER THAN THE HONDA RECOMMENDED 105,000 MILES. I WAS SURPRISED TO DISCOVER THAT THE MIDDLE REAR PLUG WAS ONLY FINGER TIGHT AND AS A RESULT COMBUSTION GASES WERE ESCAPING BETWEEN THE PLUG AND THE HEAD. ACCORDING TO WHAT I READ, LOOSE PLUGS ARE AN ISSUE WITH THIS ENGINE AND CAN EVENTUALLY DAMAGE THE CYLINDER HEAD AND COIL PACKS, LEADING TO COSTLY REPAIRS. A SECOND PLUG (PASSENGER REAR) WAS EXCESSIVELY TIGHT WHEN I REMOVED IT BUT THE REPLACEMENT PLUG APPEARED TO THREAD BACK IN FINE.) I BELIEVE THIS ISSUE DESERVES FURTHER INVESTIGATION. THANK YOU.
