Yup like said above about priming the oil pump.
its not relaly needed unless its dry from the start. Even then you can get away with using some motor oil in the pump its self as a prelube, but it will build pressure on its own regardless as soon as the motor is started.
I have used white lith. grease, works well, and does break down and blends with the oil...which is good and bad at the same time. It will make your oil milky in color, making you think you have coolant leaking into the oil supply. That always sucks, when you find you you don't. I am against using this myself for this reason only...the color change of the oil after its circulated.
From now on, I use Vaseline as my oil pump prime. It will break down into the oil when it warms up. But after a start up and everything is cool, say you do an oil chance, and decide to cut apart your filter, you will find big chunks of the stuff that have not broken down yet. Thats not bad, cause they may have hit and stuck to the filter before they had a chance to get warm enough to break down completely. Normal, and will not cause any problems with anything what so ever. Just posting my findings what I have seen personally.
