    Default Noisy motor, whats wrong here (video included)

    The car is noisy when it starts up now. It's seems to be coming from the front of the car and down the bottom. It's noisy-est when the car first starts. There appears to be a bit more induction noise also. Been chatting to a few people and they say it could be:

    - the water pump bearing is worn
    - timing chain tensioner or hydraulic lifter

    Here is the video of what the motor sounds like. It 2 meg in size.

    Can you guys help me out?

    I'm thinking it's a streteched chain or broken tensioner.

    Here's the ETK parts i'm looking at..

    hard to say. From behind the pc it sounds like an waterpump going bad. The tensioner should make a more destinctive rattle sound. Good luck in finding it, hope itīs the tensioner though. Thatīs cheap and easy to fit.

    Yeah. Though I hope never to have the occasion to hear what a failing tensioner sounds like, I'd imagine it wouldn't sound like this. This definitely sounds like an accessory bearing to me. Do any of the pullies look a bit cocked out of alignment?

    You could always pull the belts off and see if the sound goes away.

    If you do troubleshoot it down to a failed accessory bearing, stop driving the car until it's fixed. I don't mean to make you paranoid, but when the alternator bearing on my dad's Suburban failed (long ago) - he ignored it until it turned into a full metal-on-metal squeal which ended in an engine fire. It wasn't bad, since the alt was at the top of the engine - but, just.. a warning.

    would not have expected that!

    the chains dont really stretch kriss,
    check your pulleys bro.

    Default I have an update

    I was going over the car again. I'm talking about the bottom belt on the right hand side on the car.

    The noise is seems to be coming from this pump, the one on the right of the pic. http://www.bimmer.info/forum/attachm...tid=1076&stc=1

    the belt it on really tight, there is no play in the belt at all. I have a good feeling this is causing the loud noise. I never adjusted belts before, can anyone give me some advice (hint hint...lowell) on how I can loosen it.

    Default That thing a ma bob

    is the a/c compressor.

    If it is a suspect of the noise...just dis-com-booberate the belt and see if the noise goes away.

    If it does, then your a/c compressor clutch or compressor is bad.

    Drop $1000 at the a/c shop and pass go.

    Check out Harbor Freight for a mechanic's stethoscope, they have them cheap and a scope is great for finding the source of a scary sound.


    Vee ave vays of dealing vid your kind...........
