A few quid for some rocker cover gaskets and an hour of your time - it ain't hard.
Although..... wasn't there talk of the later cars having self-adjusting hydraulic tappets... [url]www.pistonheads.com/gassing/topic.asp?t=56651&f=11&h=0&hw=hydraulic[/url]

RoyC you are absolutely right. The point is you can't tell just by looking - the hydraulic tappet box is on the BOTTOM of the push rod, ie against the cam in the Vee of the engine - the rocker gear itself, under the rocker covers, is exactly the same as non-cat cars.
I tried to adjust mine, but knackered them and had to reset them.
If you are sure that the tappets are noisy, then it sound like you have a dodgy tappet itself, which needs more than just an adjustment, I'm afraid...
Check carefuly where the noise is coming from, either with a stethoscope or a metal bar, like a socket extension etc, between the engine and your ear (and not near any spark plug leads, because 50kV through the brainbox isn't good for anybody!)
