    It sounds like your engine may have developed a valve lifer noise but there is no way for me to tell for sure. You will need to have a qualified technician diagnose the problem before anyone can give an estimate for the cost of the repair.

    I have a 2002 GC with the same problem I used a product by seafoam that free stuck lifters. It worked for the summer but once it got cold it came back After treating it for the 2nd time it died down but didnt go away completely. Miracle oil works also Just use a half of a pint and pour ut into your engine block You may need to ride it for several hundred miles in order to free lifters. If that does not work you may have a collapsed lifter
