Turn my motor off and a scrapping sound, everytime i turn it off sounds like something is scrapping under my hood like metal. any1 got an idea about what it could be?

 

have you tried lifting up the hood, then having someone turn the car off while you are watching the engine? that might help you localize the problem.

 

spun bearings?

 

rocker arms?

thats what I was thinking..does it make the sound when you start up in the am??

 

i installed my motor with no a/c belt. the a/c pulley was rubbing against another one.... at first i thought it was a leak in my gasket from the TB to the mani. anyways to fix it, i just released the tension raised the pulley up and tightened her down... problem fixed... hope it's just as easy as that.

added: it was pretty consistant then after i'd turn her off the sound would run down(get quieter and softer), until it was off.

starts up fine, Some times i think it is my alternator belt but would a belt make a scrapping noise? Usually when i turn my car off i can hear the air coming out from the intake. But not i hear a scrapping, I guess when i get home i will try narrowing it down. thanks for you help. I hope there is no big problems.

 

it could be the alternator

lmao wow, what random guesses, that point to absolutely nothing.. might as well be saying it's the cd player or something

where is the scraping noise come from? is it high pitched, or low pitched? does the sound slow down as the motor shuts off, or is it a constant sound? is the only time youve heard it when you shut off your motor? have a friend help you to pinpoint it.
