    Strange noise from my Z18XE?? Help needed!

    Ive been experiencing a strange rattling noise from my Z18XE coupe, took it to a garage & they told me it was the cat breaking up. So today fitted a 2nd hand1 with only 14K use.

    Guess what.......the noise remains! So was wondering if anyone has experienced the same thing & could help me pin point the cause of the noise? Ive been told it could be a tensioner but Im sure it feels like im down on power!

    Any help or advice would be great!

    Cheers guys & gals, Paul

    Ive just had a thought........my dad had a brand new 2.2 coupe a few years back & after 5K the engine was knackered as the oil pump or oil pressure valve wasnt working properly.

    Has anyone had this problem with the Z18XE as im very concerened now as I do 40-50miles a day!

    Paul when do you hear the noise? i had a noise on my car the other day, it was a rattle that came in at about 3k revs, spent hours trying find it and it turned out to be the air box doing it, only found out when checkng my panel filter because i got so pissed off with trying find it!

    As said before is the oil ok? might be worth dropping it out and changing it just to be sure?

    another thought is has your vectra c pipe worked itself a bit slack because i have had that rattle before as well?

    I hear it sumtimes when starting it from cold but others when ive done a few miles, thats when its been really noisey! its the fact it does seem to be down on power that concerns me!

    I have checked the oil & its fine, only had it changed in July when it had a full service!

    The noise definatley seems to be coming from nearer the bottom of the engine bay, not from up the top, so cant be loose air box or intake Nick.

    Have you actually had the car up in the air with someone revving it while you listen for the noise underneath ?
    Could be baffles in the centre exhaust, loose heatshield etc, thats the best way to go about it
