Oil is leaking out of valve cover gaskets. BAD! No power. Exhaust fumes'll make ur eyelashes curl up. Runs super hot al the time. I understand they're known for that and I've had 3 cars previously with more or less the same motors but this 307 runs super hot. Someone mentioned cleaning the drain back holes. Not sure if its something I should get into cause not real sure it's the problem

I don't see the connection between oil leaks, having no power or running too hot. They may be separate and individual problems. Plugged exhaust could account for low power and high exhaust temps but not engine temps. You need to try to resolve these problems individually before assuming they are related.I's fix the obvious things like the oil leaks first.
