How to Fix Loud Valve Noise in Hyundai Santa Fe?
1 Answers
Modern Hyundai Santa Fe valve noise causes and solutions are as follows: 1. Caused by clearance between hydraulic valve lifters and camshaft (or valve seat). The clearance is mostly due to excessive wear of hydraulic lifters, causing rapid oil pressure loss inside the lifter and resulting in noise. The hydraulic lifters need to be replaced; 2. Noise caused by excessively high or low crankcase oil level. The engine oil level needs to be checked; 3. Noise caused by dirty lifters. The hydraulic lifters need to be cleaned; 4. Noise caused by oil being too thin. Replace with oil of appropriate viscosity; 5. Noise caused by low oil pressure. The cause of low oil pressure needs to be checked.
