Hi. I saw your posts about the engine rattling noise that no one could ever answer. I have the same dreadful rattle when idling and when breaking - or should i just say below 2,500 rpms. When I rev the engine it goes away. I have not loss of power or bad idling etc, performance is perfect. I do know I have a power steering fluid leak and need a new pump but not sure if this is related because the rattle comes from the top of the engine passenger's side by the dipstick area. Just wondering if you ever figured out what yours was. Thanks, any help will be appreciated. Les
