hey guys

ive been reading a few posts about the tappets, and think i may have them too, as for the last week ive been noticing this ticking noise in my car, however for me its only when the cars been running, i dont hear any noises when the engines cold or for the first 10-15 minutes

i was wondering could this still be tappets, or is there anything else i can check to see what the problem is, and would a service fix this, because its due a full service any time soon

thanks for any help
