I hear this noise from where the serphine belt is. it makes ssssssssssssssss noise like air is leaking and possibly the belt scraping against some part. i have absolutely no idea where this noise is coming from. i changed my water pump, alternator about 2 months back. im losing no coolant. serphine belt does look damaged on the surface so i was thinking its hitting something but i really cant tell whats going on...

I sprayed around the engine bay to see no leaks. does anybody have a problem with pullies go bad after a while?



and comments/suggestiosn would be appreciated

 

You can deffinetly her a leak of some kind, could be a vacuum leak somewhere, I don't think your belt has anything to do with it. I would check the intake manifold for any leaks

 

exhaust leak

 

Get a squirt bottle of soap and water and start spraying everything and see if you get bubbles anywhere.....

 

Would like a gasket on the external waste gate is blown..

 

i see no vid

 

hmm its def not air leak. it seems to be something scraping.
do pullies go bad after certain miles??

 

any opinions on pullies going bad so i can kind of pinpoint where to look? its not air leak

 

simple man just go one pulley at a time, pour a little bit of water directly on the pulley see if the noise goes away, if it comes right back its that pulley, if it dont go away, go to next pulley and repeat, if noise never subsides try a new belt idler pulley and tensioner.....pretty straightforward.
good luck

 

wow water? that didnt even cross my mind.
ill give that a try

 

Take the drive belt off completely and start the car if the noise goes away you know its a pulley then just narrow it down
