Hi, I have an almost new tdv6, which is supposed to have a quiet engine, well when I start mine from cold and drive it for about a mile I'd say the clatter it makes is getting on for td5 quality, surely it should not do this. The engine has a regular tapping noise whether cold, warm or fully hot, but is far worse during the warming up period. It sounds like an excessive clearance somewhere to me, but it has hydraulic tappets so am at a loss to know what is wrong here. Apart from the nasty noises it seems to perform ok, any Landy Techs out there got any ideas.
