Forgive my ignorance but I'm a relatively new Merc. R230 SL owner. I've had my 2006 SL 350 for 6 months now and recently the tappets started to make a tapping noise. I checked and topped up the oil and they quietened down. Can anyone tell me if the valves and tappets are hydraulic and self adjusting. As an aside, the vehicle is due a B service pretty soon.

Most engines are hydraulic to-day, when was your oil changed last? i can see your in for a service. Make sure the right oil is used it will give you problems if you use a thicker oil . It may be that your oil as gone thick ,to a state that it wont lubricate the moveing parts of the engine fast enough.
