I had to take out the three bolts indicated by the red arrows in order to remove the old timing cover. At some point, I had to rotate the crankshaft in order to remove the vacuum pump while it wasn't under load. I don't remember exactly, but these 3 bolts may have already been taken off when I rotated the crankshaft. Now that I'm reassembling the timing cover and everything, is it ok for me to just screw in these three bolts and call it good, or did I potentially mess anything up with the injection pump timing when I rotated the crankshaft?
I also made a mistake and tried reusing one of my old timing cover bolts. I screwed it into the location circled in green and it broke off. I'm not planning to take everything apart again in order to drill out this single bolt. It was far too frustrating to put it all back together, so I'm hoping it will still seal with all other bolts in place. I applied the orange Mercedes 001-989-89-20-10 sealant (as indicated in the photo) to the timing cover mating surface and where it touched both the head gasket and the oil pan gasket. I bought all new bolts from Fastenal and torqued everything else according to the FSM specifications.
