NHTSA Complaint #10052483 — 1994 ISUZU RODEO

THIS IS AN ONGOING DEGRADATION OF THE HYDRAULIC LIFTER SYSTEM THAT WILL LEAD TO AN EVENTUAL ENGINE FAILURE. ACCORDING TO ISUZU MECHANICS, THE HYDRAULIC LIFTER SYSTEM IN THE ISUZU V-6 IS PRONE TO OIL SLUDGE BUILD-UP AND THE PREMATURE FAILURE OF THE ENGINE CAN ONLY BE AVOIDED THROUGH THE REPLACEMENT OF THE HYDRAULIC LIFTER SYSTEM. WHEN FIRST DIAGNOSED, THE MECHANICS USED A OIL CLEANER TO QUIET THE VALVE TRAIN. HOWEVER, AFTER MULTIPLE CLEANINGS AND SWITCHING TO SYNTHETIC OIL AS ADVISED BY ISUZU THE VALVE KNOCK REMAINS AND CONTINUES TO WORSEN. SEARCHES ON THE INTERNET OVER THE PAST YEAR INDICATE THAT THIS IS A WIDESPREAD PROBLEM WITH THE ISUZU V-6 AND HAS OCCURED WITH SIGNIFICANT REGULARITY. SO MUCH SO, SEVERAL WEBPAGES ARE DEVOTED TO THE PROBLEM.*AK
