Corrdad Posted June 18, 2016 Share Posted June 18, 2016 I am having a high pitch whine from the engine compartment between 10 mph and 30 mph. I have been told it's the idler pulley and is a common issue. Anyone else have this issue and if so are there aftermarket replacement parts that can keep this issue from coming up again. Engine is 496. Thanks Quote Link to post Share on other sites
