hi , i'm new to this forum just need a little advice in what to do about what i think are noisy lifters , i get so much diffrent advice from many people about the oil i should use , some say thicker and others thin , i currently have shell helix 20w50 in my engine and also added lifter cleaner , the noise is not has bad has it used to be but its still there , does anyone know what oil i should use to stop the noise completly or do i have to replace lifters , the car is 92 mod ax tx5 4 cyl, thanks in advance
