Happyhands here.im new to the club as i just got my first FTO last week.bought a 98 GR.seems fairly standard with 18" BK alloys & what i think is a K&N panel filter.everything seems fine with the exception of noisey tappets.just wondering how often they should be changed & is it a job for a professional or can it be done easy enough by someone with "ok " knowledge of engines ? Any advice would be great.
