have been reading throu the threads, i own an 02 plate st170 and the engine sounds really tappetty some people say its sticky valves others say its ecu/sensor problems. has anyone had a really noisy - tick tick tick tick ticking that just dosent go away, at the moment the car sounds like its a 1992 battered old fiesta that needs scrapping.

the noisy becomes quite apparent when engine warms to normal operating tempreture and isnt so bad when its cold but its still there.

p.s its not long had an oil change and that doesnt solve the problem.
