i have an 02 rsx base dat i crashed 6 months ago n now i got an 05 type-s....point is my 02 base is making this weird noise dat i cant point out where its coming from but it sounds like when water is going down the drain. There was a check engine light like a month ago but i just turned it on today and no CEL but the sound remains and i need to sell the car and i know no one's gonna want the car w/this type of noise...can anyone help???? if nore info needed just ask i need to get rid of this quik thanks in advance

 

need to be more descriptive, plus it is going to be hard to troubleshoot online since no one is near the car.
