    hey guys

    well i know its a very vague question with multiple possibilitys of what it could be

    but as of yesterday afternoon ive started hearing a rather loud metallic grinding sound coming from my engine bay, sounds like its coming from just under the belts OR behind the timing belt cover,

    i took it to the local mechanic but he was too busy to actually poke around and said he needs to take all the covers and such off to check out the problem, and told me to come back on monday and he MIGHT have a look.

    he also told me not to drive it because it might be causing some engine damage (HERP DERP, hence why i took it to him), BUT i need it for work during the weekend and the coming week... and the big cruise ive been looking forwards to is next sunday.

    so im hoping all of the forums expertise in the way of the Z may help me out a little

    thanks in advanced for all help given

    just happened and is staying the same, i found it rather odd for it just to start from no where

    Aircon idler often gets noisy. Take the aircon belt off and see if that helps.

    If it's a idler for the timing belt then I wouldn't be driving it anywhere!

    Borrow your mate's F6 Zach. Then crash it once you've gotten home again, for good measure.

    Does the sound increase with revs, while stationary?

    And long shot here.... but did you ever manage to get that throttle cover bolt that fell, out...?

    Oh, Martin, did you end up topping up your water or at least checking up on it after you left?

    Sure did. Forgot 3 times, but then did it. Barely took 1/2 a water bottle.

    I called the wreckers, they said they're good for a return. I've been hearing you can repair alloy radiators though? :confused:

    I've always been told the opposite. I would never trust a repaired aluminium radiator either way. Even if it were possible, the guy who tested it told me it was so completely screwed. Remember all the sides on both ends the amount of rust?...

    How long is a piece of string ????. While I appreciate your pain at your car suddenly making strange noises, especally with a trip comming up. But you and your "mechanic" need to take a step back and take a course in car problems 101. But my educated guess is that it's the losse nut behind the wheel.

    Why don't you make a video (with sound) so we can hear it. You can post it up to YouTube or any of the other media sharing sites, then we can all have a listen. You don't need to run it for very long.

    How does an alluminium radiator RUST???

    Physically impossible!

    Perhaps corrode is a better description, shit happens:)

    My apologies. The amount of brown coolant that had dried on both sides after what I guess must have leaked out due to numerous small cracks / holes over it? And also the occasional blotch over the middle. Should have worded that a bit better... End point. That genuine AMS radiator is screwed.

    They don't rust but corrode if they are earth to the car body.
