    Default Squealing noise after intake gasket and manifold repair. 1999 Park Ave

    I fell victom to the leaking upper intake manifold. I caught it right
    away went I started the engine it missed slightly and I noticed the
    coolant was low. I called the Buick dealer asking him about possible
    problems. He told the intake gaskets were most likly the cause. (He
    never said anything about the upper manifold failures.) I replaced the
    upper and lower gaskets and went for a drive. Everything was good until
    I was about a mile from home it started to miss and white smoke was
    coming out the back. After calleing a biddy of mine who teaches auto
    tech class he told me about the manifold problem. I flushed out the
    engine again and installed the new upper manifold and gaskets. The
    engine ran fine so i took it on another test drive. I had spilled some
    oil and antifreeze on the engine so I went to the car wash and rinsed
    it off. Afterr that everytime I slowed down it sounded like the belt
    was squealing. When I got back I took the belt off and to my surprise
    it stiill did it. Right noe i have the oil pan off and I am checking
    the bearings. I will let you know what I find. Thanks, Mudbone

    You are wasting your time! Here is what you will find. You forgot
    to install the o-ring seal for the PCV valve in the new upper intake
    plenum. Fix that....and your squeal will be gone!

    We've "been there/done that" in our shop.

    By the way, you ask the dealership what could be the cause, and then
    make a note about the fact that they "didn't say anything about the
    upper manifold failure"! You are pathetic! What do you think the
    dealerships are for? Your personal info station? You didn't do the
    research, you screwed up. And on top of that, you weren't careful
    while doing the job and forgot something. Please don't blame the
    dealership for your fuck-up's!
