engine has lifter noise, ting ting, long known issue

This is a well known issue with this engine. It is documented every where and Chrysler discontinued this engine due to some of the continued issues. This car has had oil changes every 5k miles and now I will be stuck with a probable $2000 repair bill since it is out of warranty. I am attempting to contact someone within Chrysler to help someway with some of the bill, but it seems impossible to get any help from Chrysler.
