hi all a week ago iIbought my first jag and I'm so happy with it, it's a 2.5 v6 on an 01 plate, full service history and only done 1600 miles, it's in mint condition, BUT, there is a tapping sound coming from the engine, I've been all over it and can't tell what it is, it seems to be coming from the centre of the engine 'bulk head side' i thought it was a tappet at first but it's not fast enough for that, it's more like the sound you get when you have a stone in your tyre. I've listed to the belts and pulleys and they seem quiet, i have used 'tappet stop noise' in the oil, has any one else had this or can shed some light would be gr8
