NHTSA Complaint #11383065 — 2008 CHEVROLET AVALANCHE

I HAVE A 2008 CHEVY AVALANCHE LTZ WITH THE 5.3L V8 ENGINE WITH ADAPTIVE FUEL MANAGMENT. IT WAS PURCHASED USED WITH 120K MILES. IT BECAME APPARENT THAT THE ENGINE WAS CONSUMING OIL, 1-2 QUARTS PER 3000 MILES. RECENTLY THE ENGINE STARTED PRODUCING WHITE/BLUE SMOKE ON START UP AND OIL CONSUMPTION INCREASED TO 2-3 QUARTS IN 1500 MILES. MY VEHICLE IS CURRENTLY AT A MECHANICS SHOP AND I AM TOLD THAT FOR STARTERS I WILL NEED NEW VALVE COVERS THAT ARE REDESIGNED FROM THE ORIGINAL ONES AND THAT EXCESSIVE OIL CONSUMPTION IS COMMON ON THIS ENGINE. I HAVE READ OF OTHER OWNERS THAT HAVE HAD TO HAVE PISTONS/RINGS, VALVE COVERS REPLACED, AND A BAFFLE PLACED INTO THE OIL PAN TO MITIGATE THE OIL CONSUMPTION. THIS SEEMS TO BE A FAIRLY COMMON OCCURRENCE THAT ISN'T A TYPICAL MAINTENANCE ISSUES SINCE THESE PARTS WEREN'T OEM WHEN THE VEHICLE WAS MADE. IT SEEMS UNACCEPTABLE TO HAVE TO HAVE OEM MODIFICATIONS COMPLETED OUT OF MY POCKET FOR SOMETHING THAT SEEMS TO BE IDENTIFIED AS AN ISSUE WITH SPECIFIC PARTS MADE TO MITIGATE THE ISSUE. I AM VERY CONCERNED WHAT THIS ACCEPTABLE OIL CONSUMPTION WILL MEAN FOR THE LONGEVITY OF MY ENGINE.
