it's not really necessary, just install it and go. but you can if you think this thing sat so long or is compromised in some way from the disassembly, nominally you just tighten screws, reinstall and never think about it again.

assembly lube is so thick it shouldn't matter but don't have so much lubricant that it runs, drips and compromises the sealing surfaces during reassembly.

you can install everything, disconnect the fuel pump fuse/relay and crank the engine to prime the entire oil supply lines before starting the engine.

Did you have symptoms from the oil pump screws backing out?

I heard you were supposed to ALSO unplug the electrical connectors on each coil pack to all of your plugs, in addition to removing the fuse/relay to the pump. Is that true?
