jimmy, i just bought a 97 e420 sport. the previous owner said she had taken the car in last week because the cylinders were misfiring. had all the coils replaced and oil change done with fully synthetic oil. car runs great but now the car is making a knocking noise. im thinking about running the quick fix thing with either mystery oil or ATF. but what do you think?
Holy thread revival batman, lol, this is like 4 years old, good find.
Ticking and knocking are 2 completely different sounds. If you have knocking happening, could be pistons, could be a few major things. If you have ticking happening, it could be the lifters. Usually if it's not bad, running fully synthetic oil in there for a couple hundred miles should free them up and stop them from ticking. Otherwise, I would take it to an MB mech and have them check the lifters. Hope this helps...

jimmy, thanks. it is more of a loud ticking. when im accelrating it will decrease, and when i let off the gas it goes away. cold start however, it sucks.
oh lord, yeah i got a great deal on it. i figure if anything, if it gets too expensive i can try to quiet it with some lucas and flip it for a small profit and look for another one. actually the day i bought this one another one came up but that had a trans problem.
