Hello folks,

After months of working outside on those rare warm days, I'm finally getting my truck back on the road after replacing the cam, lifters, and oil pump gears. I used assembly lube on everything, of course, but I would like to get the oil pump primed and oil up to the top end before I attempt to start it. With that oil pump driven directly by the crank, the only way I can think of to do this is to leave the plugs out, disconnect the inertia switch to prevent the fuel pump from running, and crank the engine over until I see oil pressure.

Is this advisable? Or should I just start it up and hope for the best?

On an unrelated note, I'm a little sensitive toward protecting my new cam and lifters, so I want to make sure the oil I use is good to flat tappet engines. I'm going to use Rotella T 15W-40 because it has 1200 PPM of ZDDP in the formulation. Should I be using a break-in oil for the first 1000 miles instead? Anyone want to recommend one?

Thanks, all.
