Looks like my car needs a new set of hydraulic tappets (one is occaisonally noisy on idle ), I got a qoute from Porsche for replacements but they were not particularly cheap. The helpful guy at Porsche says you can buy them direct from the manufacturer but he could not remember who that was.

Does anyone know who the manufacturer is and the best place to pick up a set ?

Thanks,

A.
