I think I know the answer but asking anyways. I have an engine sitting around that I want to compression test on the floor, most of the oil is drained from it. It is not literally dry inside but only has residual oil.

It's an older Powerstroke 7.3, how much oil would I have to put in in order for sump to suck some up and lube bearings while being turned over w starter? It WILL NOT be started, only spun w starter motor.

It holds something like 4 gallons installed. I'm also not sure yet what I have to block off to prevent spills/leaks, need to figure that out. I know that I could safely turn it over by hand as it is but it's going to need oil to spin a little faster.

Just enough to submerge the sump? What say? 😺😬
