A bent valve will cause the car to run rough but not crank so hard that it ruins the starter. Are you saying that the engine cranks hard? Is the car cold at the time? Hot? Have you had the starter checked? Have you checked the alignment of the starter?

Give us more information

im just saying i can turn the engine over with a wrench as im it rotating it hits a tuff area that its more harder to rotate it takes more power to get it to turn past this point and on my fly wheels its damaged its usually just that one are that is damaged it is cold at the time usually when i start it but when i get a new flywheel i get a few good starts be fore it gets baddly damged teeth i have tried all the starter tricks and i have used so manny new starters auto zone freaks out if they see me coming with a starter lol once the engine gets started though it runs great thats what has me baffled hope this info helps you thanks agin for any help

sounds like a valve may not be opening to me. does this happen every time you get a full revolution on the motor??

yes every 360 degree revolution it does it
