Hello everyone, my C280 has a very irritating ticking sound, I'm pretty confident it is lifter related. I asked my mechanic (who recently replaced my head gasket) what I can do about it, and he claims there is nothing that can be done, that it is normal and even replacing the lifters will not remedy it. He even said oil additives are a waste of time. Noise increases and decreases with revs, does not subside.

Is there really nothing I can do? It sort of lets down an otherwise elegant car. :frown

These are the steps I'd take:

1. Take the car for a good hard drive.
2. Remove about 2lt of engine oil and replace with diesel. Run engine up to temperature and intermittently rev engine to 2000 rpm for 20 minutes. Change engine oil & filter. Again, do a good hard drive.

Might work, might not but costs little.

Is adding diesel into the engine oil for cleaning? Isn't is safer to use an engine cleaner instead?

Yep, diesel for internal cleaning. Is it unsafe? I don't know being candid (using too much wouldn't be wise) but it's a very old trick and has worked for me in the past where specific branded engine cleaners did not.

For a safer bet, perhaps try 1/3 of a bottle of seafoam, straight thru the BB vacuum line and the rest into the gas tank.
Follow the instructions.

What grade oil are you using? I run nothing but 15W-40 in my C280 with 240000+ miles and its dead quiet and smooth. Try that before you drive yourself nuts. I kid you not its so quiet and smooth I got gas a few months ago while forgetting to shut off my car, like it was a old locomotive.

Is the noise all the time? it doesn't depend if the Engine is hot or cold?. when i had ticking noise from my m104 c36 i changed the oil from 0w40 to 10w40 and it dissappeard right away.
