I was replacing my cam sensor and the metal ring on the sensor opposite of where the bolt goes broke off and is stuck onto the engine and I can’t get it off. I’ve tried hammering on it with a flathead screwdriver but that doesn’t seem to be doing much and I figured I probably shouldn’t do that anymore so I don’t cause any damage. I also sprayed some penetrating oil on it cause it’s probably rust that’s causing the problem and that didn’t seem to do anything either. Maybe I’m doing something wrong? Maybe I’m just not trying hard enough.I don’t know
