engine rattling?

  1. #1
    Hey guys,

    My cars been making a wierd noise recently it sounds like rattling in the engine I can't quite figure out what it is. It happens when the car reaches about 4K revs. It doesn't make the noise on idle, I spoke to a guy he said it could be bigends but I thought you'd be able to hear that constantly not just when it revs up. There is no loss of power it still performs the same its just an annoying noise which kinda sounds like something is loose. I could try to record the noise if needed? Another mechanic has told me its not big ends but failed to tell me what it was.

    Any help is greatly appreciated

    big ends are more of a rumbling noise. check your heat sheilds aren't loose.

    It could be that, my alternator does sound dry... It seems to sound like its hissing... I sure hope its that and nothing deeper...
