I already ordered another set of each, I do not feel comfortable about the orings after they were subjected to the threads like that. This is turning into a fiasco, three times now I will have done this job.

I am very curious as to why my 1987 Factory Service Manual set published by Mercedes Benz of North America simply states 35nm torque for this job (07-1-210, delivery valve seal replacement), and makes no mention of the triple sequence.
