Hello, I've got a 2007 Impala LTZ with the 3.9L. I've looked all over this site and google trying to find some info on what is in my way to remove the valve covers to replace the gaskets. The front one has two coolant lines across it and an engine mount that looks like it will make the removal tight. The rear cover has a lot more in the way. Does anyone have a walkthrough on this process or have any tips? I'm not even that familiar with coolant lines; the one is just a top return with very little fluid in it, but the other one looks like it will be full. Can I just catch the drippings and burp the lines when I hook it back up, or will I trap air in there? I'd really appreciate any help you can get, I'm going to try to do at least the front tomorrow night.
