richandhazel 0 Posted June 17, 2011 Report Share Posted June 17, 2011 Hi All, My VR6 has developed a tap on start up. It's quite pronounced from initial cold start and disappears as the engine warms up. In fact after about 2 minutes the noise has gone. I don't recall it happening prior to changing the oil recently but I may be wrong. The oil was 10/40 semi-synthetic from GSF. I'm wondering if it's a sticky tappet? The car was sat around for quite a long time prior to my owning it. Is there a way to confirm that it is a sticky tappet and is there an easy fix without having to take the rocker cover and cams off? Is there anything else it could be? I would have thought if it was a worn bearing the noise would be there all the time and certainly not disappear within a couple of minutes?TIA Link to post Share on other sites
