Oil Priming an engine before first run

[MaximumMini]

Chrysler 3.8L V6.

Subject engine has had head off, oil pan off and one rod and piston removed for over a month.

Before putting the motor back together, I want to clean it inside. I will probably use Kerosene or Diesel fuel just to help remove any contaminants that may have found their way into the engine (wind blown debris, bugs etc).

Problem is, this will also remove oil from the bearings and oil galleys. What I would "Like" to do is pressurize the oil system so that clean oil fills all the passage ways and the main and rod bearings etc before I even crank the motor over.

On this engine, the oil pump is driven by the crankshaft. Which means I would have to crank the engine over to get oil flowing, which defeats the purpose. Is there any trick known to pressurize the oil system before cranking? Could I for example force oil up the sump intake pipe or would the oil pump just block the oil? As a last resort, I "could" just pour oil over the cam galley so that oil gets all over everything below, and hopefully seeps into the bearings.

Any better ways to do this?

Rent an oil pressure primer. I am sure there are some you tube videos but basically you put your oil in the can and fill the sump from the oil pressure switch or oil galley plug.

fill the oil feed from the block to the head with oil before mounting the head

I used a cheap garden sprayer from Home Depot on a 5.7 Hemi. Worked well, I cut the nozzle off and attached a fitting to the hose. Started with the engine empty and put 7 quarts into it through a port above the oil filter. I rotated the engine over by hand using a socket and ratchet on the crank bolt while the oiling system was pressurized with the sprayer.
