Hello.. my Honda Fit just had a loud whinning or supercharger-like sound coming from the engine. Sometimes, the sound is intermittent until it became permanent. What could it be?

bad bearings, and there are tons of them. Remove the fan belts and if noise goes away, pray it does, then find which pulley system has a bad bearin

i just checked everything and just found a wobbly pulley.. its an idler pulley I think
