its the pully , i was told that i could spark sometimes when it trys to seperate? the noise is gone and i didnt do anything, i pretty sure that pully has something to do with the noise. the muffler shop put there heat guage on the converter and said its was good but said the from the manifold down was super hot and that they had some sort of converter built into them before they connect to the exhaust so idk, the power steering house is not leaking where it screws in the steering rack its down where the rubber hose connects to the metal on right before the bracket hold both the hoses
