Consumer Description

DEFECTIVE VALVE GUIDES. THIS FIRST HAPPENED AT 13,500 MILES, AND CHEVROLET DID REPLACE THE HEADS UNDER WARRANTY. NOW IT HAS HAPPENED AGAIN AT 28500 MILES AND I HAVE SPENT OVER $3100 IN PARTS ALONE TO FIX THE PROBLEM, WHICH HAS BEEN VERIFIED BY THE COMPANY WHO SOLD ME THE REPLACEMENT HEADS. I PROVIDED THE LABOR OR THE COST WOULD HAVE BEEN $1700 HIGHER. FOUR INTAKE VALVE GUIDES WERE BEYOND THE CHEVROLET REPLACEMENT SPEC AND ANOTHER FOUR WERE ALREADY AT THE CHEVROLET SERVICE LIMIT WITH ONLY 15000 MILES ON THE REPLACEMENT HEADS. OBVIOUSLY THE PROBLEM OCCURRED DURING CITY AND HIGHWAY DRIVING.
