Some useful advise
W116's are not worth a lot of money, put it back on Ebay and buy another one.
From reading your initial post about oil leaks and metric wrenches , it's pretty that you know nothing about German cars and neither does your mechanic (no offense). Trying to perform some sort of conversion is going to get you in more trouble then you are now.
What W116 model is it? Is it rust free? It may be worth something to someone in the UK, Australia, South Africa or the far east.
Good luck and try to cut your losses before you dig yourself a bigger hole.
