Good morning all friends,

I'm trying to make the right clearance on my M115 938, W123 1978 petrol.

The valve adjutment screws are too hard to rotate for valve registering.

mercedes report around 20-40 Nm for the torque but actually i misured arount 90-100.

ALl of them are lubricated and this problems causing me to remove always the rocker arm and use a standard socket instead of using the mercedes open socket.

DO you know why? Does anyone had the same problem?


Thanks to all
