Noisy Lifter(s) Can you identify?

[mykg4orce]

Since yesterday I am being haunted by a noisy lifter problem. Its a 190e 2.6 103 engine. I took the valve cover off to detect any visual damage but did not notice anything. I added some ATF fluid to the oil and ran the car but the sound was just as present as before. I am going to change to oil right now. That will hopfuly solve the problem temporarily. I am also planning to replace the valve seals when the temperature here in Toronto goes up a little. I have the seals and all the required tools ready, I have read up on this forum about others that had problems with lifters. I wanted to know where these "lifters" are. I have attached 3 diagrams from the MB manual. If anyone could tell me where these lifters are located. Maybe I know what they are but by a different term.


thx
