Does anyone know how much to torque the two screws to on the EHA. I have '86 560SEL & did the new o-rings thing already. It worked for less than a year. So now I purchased a new EHA but I do not recall what the torque value is for the screws. I assume over-tightening will be leaky as well?
Thanks

Just tight enough to not leak... at least that's what I did with mine.

I have had our EHA off both our cars several times during the adjustments and have never used any specific torque, I just tighten till snug and have never had one leek.

3,0 (+/- 0,5) Nm!
