    Default ecotec rattle

    hi everyone this is my first post.
    my 07 plate vectra petrol 1.8 ecotec has had a rattle on start up for ages till the oil got up to the top end. but now it rattles all the time on tick over. I think I may have jumped the gun and ripped it to bits to do the hydraulic tappets but it would appear there isn't any fitted to this engine just buckets placed over the valves. could it be the pulleys that are rattling(vvt ?). not sure when you hold the inlet cam pulley and shake it it rattles but the exhaust one doesn't any ideas people ????? some advice on cam timing would be great aswell. locking cams etc. finding proper TDC. etc. thanks stuart

    WoW thats a bit unfair. A lack of replies means that maybe no one knows, better to get no replies than a pile of useless ones.
    When was the last time it had an oil and filter change? Maybe the oil is worn out. What grade of oil do you use? Have you concidered using a thicker grade of oil to see if that helps, sometimes the cheaper options are the best place to start.

    well as it happens I've actually found the problem out it was intact the cam pulleys that are rattling. they are the ones that are variable valve timing ones they are fed with oil through an oil gallery on the cam. seemingly it's a common fault on the ecotec 1.8 xer engine. £315 for them both. and I've also found out there is two tools needed for setting the valve timing. one to hold the cams in place and one to hold the pulleys to allow to tighten up the bolts so they don't move as there is no woodruf keys to hold them on place. surprised that nobody knew this as this is the uk's leading vectra owners forum.

    If posted in the evening you'd probably have gotten a reply.

    I could have told you that there is a problem on the VVT engine much as you described but this is the first i've seen this thread.
