    1.6 16v Wont Stop Tapping!!!

    Hi, our 2003 1.6 16valve astra has alot of tapping noise coming from the inlet camshaft area, so what we have done to try and solve this problem is:

    Oil change (did nothing)
    replaced all 16 hydraulic lifters (the noise went away for about a day but has come back again)

    so what else could this be?

    please please any suggestions are welcome

    You have already identified the problem to be noisy Hyraulic Lifters by fitting new ones and the noise going away for a day.

    How many miles has the engine done,

    Do you know the history of the car.

    Did the previous owner ever change the engine oil.

    It sounds like you have an Oil Pressure problem, it might be just a partially blocked oil pick up in the sump.

    Have the oil pressure checked,check and clean the oil pick up in the sump, then replace the oil with Magnatech.

    i had the same problem with mine and it was the water pump, had my water pump and cambelt plus pulls changed and it is now as quiet as a mouse. cost me £200 labour and parts with a mobile fitter

    Thanks for the replys to answer questions and to give more info:

    The car has covered 59k miles and has full service history

    The funny thing is that all the tapping happens mainly between 1800-3000rpm and all of the noise is coming from the inlet side of the camshaft cover

    This is very confusing to me and my dad who are both quite well experienced with cars/engines

    Sh!T!! Something has gone major wrong now! The whole topend sounds like its falling apart!! sounds like all the lifters are being starved of oil, going to take it to perrys tommoro and hopefully get them to sort it

    Doesn't sound good,
    make sure they call you 1st with their diagnosis before they repair the fault.(Sounds Like the Engines gone)
    It might be cheaper to get it sorted in an independent Gge.

    it was prob caused by the water pump bearings breaking, i had my cambelt broke on another astra g i use to have and vauxhall charged me 1400 to fix it cause i had to have a complete new top end, hope it all goes well.

    Yes we changed the oil the other day as we thought it would cure the tapping (5w-40 fully synthetic)

    No the cambelt has not broken.

    Its in the dealer now getting its oil pressure checked as we think the oil pump is failing
