THE OIL COOLING LINES HAVE BEEN LEAKING FOR QUITE A LONG TIME, AS A ROUTINE THE OIL LEVEL IS CHECKED OFTEN. AFTER CONTACTING A GM DEALER'S SERVICE DEPT THEY TOLD ME IT IS A VERY COMMON PROBLEM WITH THIS BLAZER AND WITH THE TRUCK NO LONGER UNDER WARRANTY TO CONTACT THE DELIVERING DEALERSHIP. BESIDES THESE HOSE ASSEMBLIES ARE ON BACK ORDER I WAS TOLD, WHICH MEANS IT IS A COMMON PROBLEM AND IT MAY BE A MATTER OF TIME BEFORE OIL FIRES MAY ERUPT IF THE LINE COMPLETELY FAILS. AFTER CONTACTING THE DELIVERING DEALERSHIP THEY WILL BE GLAD TO REPLACE THE HOSES FOR $375, IN WHICH I WOULD REPLACE MYSELF, BUT NO PARTS AVAILABLE.*AK
