NHTSA Complaint #10715965 — 2002 SATURN VUE

LOSS OF POWER AND EVENTUALLY JUST STOPPED RUNNING. TOWED IT HOME. SUSPECTED TIMING CHAIN. TOOK OFF VALVE COVER AND TC COVER. NOTICED THAT BLACK PLASTIC GUIDE WAS BROKEN IN MAIN PIECES AND MUST HAVE BEEN FOR SOME TIME, FOR CHAIN WORE INTO SOME BOLTS AND COVER. CHAIN LOOKS BRAND NEW AND NO ISSUES WITH IT. REPLACED ALL TIMING COMPONENTS (TWO SPROCKETS, CHAIN, GUIDE, TENSION ARM, TENSIONER, CAM SPROCKET, ETC)., BUT IT WOULD NOT START. CHECKED COMPRESSION (0 PSI AT ALL CYLINDERS), DOUBLE CHECKED TIMING AND WAS CORRECT. ROLLER ROCKERS WERE LOOSE WHEN CAM IS NOT PRESSING ON THEM, SO SUSPECT ALL VALVES ARE BENT. FIX IS TO REBUILD THE "HEAD". I PRESUME THAT IF THE BLACK PLASTIC CHAIN GUIDE DID NOT BREAK, IT WOULD NOT HAVE GOTTEN OUT OF TIME AND BENT VALVES. THE RECALL SHOULD NOT BE ON THE TIMING CHAIN BUT THE PLASTIC GUIDE THAT IS USED FOR THE TIMING CHAIN. HAD THIS PART BEEN METAL, THIS WOULD NOT HAVE HAPPENED. HAVE PICTURE TO SEND IF NEEDED.
