In the last few days I've thought that the car (W220 S500 2002) had been sounding a bit off i.e. a faint ticking sound. I took off the plastic engine cover to locate the noise and I'm 99% sure its from the engine itself. I checked the oil and it seems to have used a small amount but nothing major. I also checked the driveway for any drips but there is no sign of any. Its due in to the garage tomorrow so I was going to ask for an oil change to see if that helped.
The car has done 73k miles with a full service history and the last minor service was carried out about 4 months ago and 1k miles.
Any thoughts?

Cheers

 

Probably the valvetrain - noisy lifters. Try adding a little oil and see what that does.

 

cheers for that newton22 got the car back today and the new oil seems to have done wonders, now just need to get the airmatic pump changed to get back to some quiet running
