I have just pulled the moter for older oil leaks. When i pulled it i bent the valve cover bent it back down with a hammer and i still have a leaks. How muck oil can a valve cover leaks. The bent is on the back down hill side of the cover.

 

There is your problem, its on the back side where the oil runs. You can try to RVT it... About the only thing you can do.

 

Get some new/used valve covers...
