hey my engine sounds weird from time to time. i don't know what's causing it to sound like that. if u hear clicking sounds then i already know that it's the valves cause the original bent one for reasons i do not know and it clicks. but the sound that really gets me worried is that sound that goes back and forth loud and quiet. my engine also moves back and forth with it also. so any help would be great!
