tappet

hi folks , i have now got 19500 miles on the clock . the last recorded service was at 12000 miles just before i took ownership . in my opinion its starting to sound a bit " tappety " , despite oil change , etc at about 15000 miles . To get to the point has anybody any ideas on service...

Hi guys Has anyone had to do their tappets if so how easy?:dunno Did you find they needed doing?:dunno If so how far out which way and what sort of mileage?:dunno I am sure someone out there has done them themself or paid an arm and leg to have them done but was it neccessary:confused
