I dont think anyone understands, I USED lots of heat to get the last three out because the first one came out bent. I cant start the motor because it has no exhaust at all so I used a torch anyway and it still snapped. Secondly the bolt is at such an angle and in a place were you cant get an extractor in the bolt, hammer wont fit. Honda uses a almost permanent threadlocker and a lot of people wind up buying a new valve cover Ben, yes I have snapped a bolt in a car but i can always get ahold of it because there is room. Besides I dont have to tear the car apart to disconnect two hoses to be able to dyno a car for an accurate AF
