So the car is a 2004 Pontiac grand am with the 3.4L v6 and when I bought the car about a 2 months ago this noise was apparent but not as loud and it’s gotten louder and developed some click when the rpm’s drop so I know I need to fix it asap my first guess was the idler pulleys and when I went to check them there wasn’t any play in them but I’m hoping it isn’t the tensioner

I do plan on fixing my self so any help would be appreciated

So the car in question is a 2002 bmw 525i touring for sale for around $5k and has low miles and is mechanically sound it’s just the rust on one of the front passenger rocker panel and I was wondering if it’s worth paying to get it fixed or to just avoid at all cost?
