I've drilled a hole in the cam cover after covering it with grease. There's maybe a mm between the back of the cover and the cam. I can't tap the hole even with a blind tap. The tip of any self tapping screw will simply hit the cam before it starts to thread. So attaching a screw and pulling on it isn't going to work.
I read about someone that tapped on one edge of the cover to force the other side up. I'm concerned about that given how close the cam is to the back of the cover.
I saw a video of guy that welded a bolt to the cam cover and then used a slide hammer to pull it off. I can do that but I'd rather not. Any other options?
