    Petrol engine sounds like a Diesel

    I hoped someone might be able to help me with this one.
    I have an astra MK4 estate, fitted by vauxhall when new, with LPG.
    I've been having a lot of coments that the engine sounds like a diesel engine and i'm not sure if this is normal. Although the LPG works, i haven't used it yet. Does this seem normal? I've had no problems with it, no stalling, no loss of power, it's just the engine sound which sounds different to other petrols.

    Thanks in advance

    Thanks for your reply,
    I'll try but i've never done a video before but i'll give it a shot although it could take day's, week's, years even .
    In the meantime, it does sound just like a diesel, so if anyone can provide some info,i'd be really, really grateful.

    Could be a lazy lifter, or blowing manifold etc.

    The list could be endless, a video would definately help me suggest the problem.

    Try recording it on your phone or camera, then upload to www.photobucket.com and copy accross the link

    probably noisy tappets from low oil or a blown manifold gasket
