Hi, I recently have my 96 Saturn(80k mileage) changed oil in Firestone. And they did a free check on it, the report recommends: 1. 755K5 Poly-rib belt, remove/replace, Part cost .99, Labor 2. Gaskets, VS50218 Valve Cover Gaskets Set, Part cost .24, Labor 0 I think Gaskets change is due to some leakage issue(which is always there). For the belt, is it critical? And can I change it by myself? Can I buy the parts from Autozone? Any suggestion? I spent 0 couple of months back to solve the coil issue which triggered the SES light. So I want to save cost on these two issues. Thanks a lot!
