Mercedes W123: How do I go about getting the valve adjustment nut back on .

Fri, 27 Apr 2018 13:16:56 -0700

So upon following the instructions for the valve adjustment. I was turning the bottom nut to loosen the bottom lock nut a bit and then while i tried to turn the top nut to adjust the gap the adjuster nut moved to the side and popped out and went flying.? Luckily I was able to find it but no metal was damaged off so now how do I go about getting the top nut back on.? Do I have to take off the levers that touch the cam lobes.??? Plz help.? Also is it a bad thing that the valve gap clearance on all of the valves are touching.? the levers and valve adjustment nuts have no gap at all. On any of them.? Im guessing it's pretty bad.

Mercedes W123: Left turn signal will not blink when I press the break paddle.

Wed, 25 Apr 2018 06:26:32 -0700

Hi , my left blinker will not blink if the break paddle is pressed, it will sometime hesitate to blink and will blink once or twice. The right side seems fine, flasher relay replaced, the emergency switch is new. Again the right side is not affected at all.

However what I noticed is a little green light is on where the arrow of the left blinker will blink on the instrument cluster if the break paddle is pressed , but the blinker switch not engaged to blink . Please help, I have no idea what is causing this..
