    not sure on your noises but you shouldn't really be in 5th doing 30mph IMO... if its as you say and when you put your foot down at 30mph in 5th the sound could (I guess) be the engine struggling as its in too high a gear?!

    just a thought... try it in 3rd, then try it in 4th. see if the noise is there then, or if it gets louder/more apparent the higher gear you're in, and there's your answer

    yeah i know i shouldnt drive in 5th at 30 but it also does it when the revs are dropping say 3-4k,
    its strange cause it doesnt do it when im giving it some, its not cause the engine is struggling its a different sound.

    maybe its your aux belt tensioner but best to get it looked at

    as for the noise on idle i could be you hydrolic lifters as its quite common for them to be noisy on an LET

    it always happens at bad times, got the dreded insurance this week thats going to rape me of a grand so hope its nothing serious,

    would it be best to take it to vx cause they should know more about it? or would any decent garage know about it?

    hard to say mate coz some garages know more than others

    i recommend going down to vxl, park up and open your bonnet and pretend your doing something and when a tech walks past ask him and say you'll sort him out a drink for having a look, coz people have done it to me enough times
