Lifter/valve noise #2 cylinder! Was told it was lifters but no! I replaced them. I pulled lifters and rockers out checked them thouoghly replaced lifters. Rockers show little signs of wear, bearings ect. Valve stems and springs appear fine. Take rockers off noise might go away. Take lifters and rockers off and noise does go away! Engines runs smooth when all together just a horrible noise! Mileage 145,000
