Angle for MMO soak

[dieselbenz1]

Ok last year when I checked cold compression I had only 260 psi in number 5. Since I am planning a vacation I was thinking of soaking number 5 in MMO. Without removing the valve cover I can find TDC and since the firing order is 1,2,4,5,3 5 should be at the bottom of its stroke at 36 degrees. So then just fill it up through the injector nozzle and wait 2 months!

Better yet would anyone know what position is best to fill all the cylinders? May as well do them all I guess. Should I be putting in known volumes of MMO?
