On start up, my 97, slk230 has a noisy tappet, the car is not used much, and I was wondering if there was an additive I can put in the oil to help the situation?
Hi Malcolm, it stayed for about 20 minutes, I was talking to a chap I know, car ticking over, and it just went quiet, and then was ok for the rest of the day, new oil and filter was done about 6 months ago, but it was done by the same Mercedes "specialist" who fitted the wrong plugs and lied about my other "faults".....maybe he has used cheap oil??
