Question about 2003 Mercedes-Benz SL-Class
1 of two things. They are hyd lifters so there is no adjustment to be done. So it is either a lack of oil pressure or an odd thing but does happen, a small piece of derbis will get into the pressure bleed hole, the oil is push out as the camshaft comes up to open the valve, the lifter will collapes and not re-pump up due to the hole being closed off. Im quite sure AMG rquires Mobil1 oil, sometimes extream temps either higher or lower will change viscosity requirements. you may need the 15W 50 to maintain enough pressure where you are at or it is possible the oil is broke down so bad that it is no longer able to maintain the correct amount of PSI. 1st things first. Put a mechanical oil pressure gauge on the motor, observe pressure after complete warm up. If it is too low go to the 15W 50 weight oil. If it is an oil pressure issue two things should happen. 1 the lifter making noise should be farthest from the pump. If not you should do a very carefull inspection check psi with mechanical gauge 1st if it's low, then you'll have to find the causeor cause. if psi is within spec you have a bad lifter IE: dirt or collapsed spring.
