I'm putting together a 2.3 for my Ranger. The engine has been sitting for a year. I'm putting a new oil pump in and checking the torque on any internal bolts. When I get it all buttoned up how do I prime the engine? On my old 390 in my Fairlane I just pull the distributor, put the primer shaft in my cordless drill and run it up until I get pressure and oil to the rockers. I'm not sure what to do with my 2.3? Any help? I know to prime the pump before installation, I'd like to get fresh oil to the bearings prior to cranking.

Thanks,
 
Typically the assemblly lube is good enough to get you started, I'm unsure about something that has simply been setting.

Being unsure I would likely drain the oil, pull the valve covers and refill while coating everything really well. Don't forget to put a new filter on it too.
 
You have a plug or cam sensor in the dist hole.I just unhook the timing belt and take an old dist or shaft and primed the pump that way.I don't think I ever started a new motor on just assembly lube.
 
Between the assembly lube preventing contact between parts and the oil pour throughout the valvetrain coating all the surfaces and being allowed to drain through all drainholes rather than just at the fill tube, allows for plenty of lubrication for the first few seconds of crank/run until the pump puts the oil through. As long as the filter is full of oil the engine should receive oil within the first 5 seconds of cranking. In his case I would have to say the valvetrain pour would work. Didn't know about the distro plug, nice info.

Remove the plugs and spin the engine over by the starter until you have pressure. I wouldn't start the engine without oil in the oil galleys.:)shady
 
you can take the distributor dummy shaft out and use the same process as your 390. on the engines that you cant do like this i just unplug the fuel relay and bump the starter several times and then crank on it till the oil pressure gauge comes up
