Here is apparatus I use to preoil. Goes in engine gallery passage.
Valve closed at bottom, fill with oil thru 1" plug, attach airhose, open valve...oil is BLASTED thru oil passages to bearings, cylinder walls...etc.
Usually I wait till engine is mounted on aircraft.
This time I felt I had assembled engine a little dryer than usual; so I preoiled off ac.
Masking tape is no substitute for having temperature bulb in oil screen hole or oil pressure line hooked up.
Didn't get any oil on floor. At 80 psi oil hit the cardboard box leaning on the shop front door.
Now with holes plugged will have oil everywhere inside engine.
A bigger reservoir would be good.
