If you want to adjust the valve clearance, you'd better buy a valve gasket. I thought of just unscrewing the valve cover, but have changed my mind. I'm glad I got them and removed the covers and you know what? One of them broke! My advice to everyone: please order before adjusting the valves. I am not being paid to leave a review. Just a note.
