I think it’s around 8nm so yeah 71 inch pounds sounds right.Agreed: if you over-tighten that little screw you can crack the plastic around the insert on the conductor plate. Not fun...
Dropping the pan and valve body is not without risk, but if you have a clean place to work it’s a straightforward process. You will want a torque wrench for the many bolts that clamp the solenoids and valve body together... 71 INCH pounds if memory serves?
