It would be nice too see some pics with the hood open....to add imiges or files , after you click the "post reply" icon scroll down a little further to "manage attachments",click one of the "browse" icons and then choose your media location (Documents,pictures,etc...),choose your item and "upload" it..... It's actually pretty easy
When you here this noise I would assume the hood is in the "down" position most of the time ?? Latched and shut ??
I guess what I'm asking is,, have you ever heard the noise while sitting at an idle (or revving) with the hood open ???
