    Uncle Scotty's Cocktail mix
    Oil changed a few weeks ago
    Amsoil is the only oil i've ever used in the car.
    I think that's about it.
    Car has 112k miles.
    The motor should be around 30-40k
    New clutch was installed by Turbo_Turtle a few months ago

    Problem:
    I walked out to my car while it was running.(I have a remote start)
    And noticed some noise coming from the engine bay. The noise seems to be coming from the front of the motor but I may be mistaken. Its almost like a metal rubbing against metal sound. Power has not been effected and the car seems to drive fine. I have some video that I will upload and post a link to. Otherwise if any one is available ASAP to check it out I would greatly appreciate it. I'm located in Richfield near the Mall of America. Text/call Anthony at six one two 810 eight nine seven three.
    Thanks in advance.

    Edit: Here is the link to the video I took. Not the best shooting, but it's more for the sound than anything.

    Its really really hard to tell from the vid lol. Are you talking about the constant "scraping" noise? If so, probably a failing belt tensioner or pulley.

    were new pulleys and tensioners (and i suppose belt too) used when the motor was replaced?

    Sorry it was windy out. I'll try to make another vid. The previous owner had the motor replaced so I'm not certain. Yes that's the noise I'm speaking of. (Assuming it is a pulley or tensioner) Is the car safe to drive in this condition? I'm assuming not.

    Well to narrow it down i would start by removing the ac belt/tensioner if the noise goes away u have found ur issue. If noise persists i would pull the timing covers and do a visual inspection of the pullys and tensioners of the tbelt unless you know for a fact its a new tbelt and tensioners.

    It doesnt even look like the small pulley is spinning. It may be the video? Check on that, if it isn't spinning.... Winner, winner chicken dinner...

    It's just the video, it's definitely spinning. I'm gonna try and check the A/C pulley today. Could still use a hand if any one is available.

    Thanks everyone for the input. Sheen was able to help me out. It was the AC compressor or pulley. Gonna try replacing the pulley first.

    Dealer sells the pullys new as does alot of the local parts stores.

    If you want to make sure its the pulley and would like to take one off and put it back on i would let you borrow mine as my ac system has a leak somewhere and its not really doing anything having it hooked up.

    I hate the new plastic ac pulley. The older metal pulleys where better.
