hi guys .. looking for a bit of advise vectra cdti 150 . 67k when started on a morning sounds like a old fiesta goes off after few seconds more top end rattle/tappet as if lifters are draining of oil then when ticking over you can hear this rattle when you drive off if window is down you can hear it tapping away after about a mile seems to go really starting to irritate me now also when driving constant speeds will stutter for split seconds randomly then be ok already had injector plugs ,inlet manifold,new egr ,throttlebody and clutch and flywheel drives nice apart from this any comments would be appreciated..
