How did you warp it?!?! My gasket died on my car. When it went out, it managed to fill cyl #1's spark plug tube with oil. It misfired like nothing else, didn't throw a CEL though. Weird.
A new gasket from FelPro is like $20. Changing it can be done in almost no time.
Make sure to torque the cover down or it will leak, again.
