#1 of 2 Chevy rattling noise by dragos426 Aug 23, 2009 (8:33 am)
My 98 Caviler has just started making this horrible rattling noise in between gears. Its sounds like rocks shaking in a coffee can. It happens when I excelerate just after the car changes gears (its automatic). PLEASE HELP!!! Replies to this message: claytonio (Dec 04, 2009 6:55 pm)

Replying to: dragos426 (Aug 23, 2009 8:33 am) You may want to give your PCV valve a check. The springs tend to wear out on them contributing to vacuum loss. If this doesn't fix it, you have a vacuum leak somewhere.
